I found this very interesting: Enjoy, Earl -
The doesn't work. If the bike runs a while the tach moves to about 1000 RPMs, but doesn't respond with engine speed changes. I have removed the gauge and it moves freely. Any thoughts.

Went to crank bike yesterday and while hitting start button I heard a diffinate sound then sound of engine turning over changed to it just turning over but no fire and start. I don't hear the clicking of the fuel pump pressurizing anymore. All fuses appear good. I'm thinking fuel pump relay failure. Any thoughts? -
Yesterday I tore down my '83 frankenbike with the '86 engine. I just need finish by dis-assembling the front end and pull the engine to get the solid engine mounts so I can sell them. It looks pretty interesting on the center-stand with just the triple tree down intact attached to just the main frame with engine - that's all that's left intact (I pulled everything off of the frame including sub-frames & wiring harness.) And then the engine looks funny since I pulled the performance clutch, slightly used water pump assy, aftermarket high output stator assy, like new '83 carbs (new diaphragms & floats), ingnition coils,etc., & Vboost plenum with manual linkage off the engine. I want to know if there is any interest, meaning anyone having '83-'85 2nd gear problems that would be interested in the good tranny parts out of this '86 engine. I thought I would crack the case and pull any or all tranny parts if someone wanted to buy them. Otherwise I won't waste my time and the whole engine will go to the metal salvage yard along with parts that I don't think will sell, such as the main frame, probably some chrome handle/ crash-bar parts, etc. Please PM me or email me. Thanks, Doug -
I think this is just pretty darn cool. http://www.foxnews.com/leisure/2012/10/02/world-smallest-supercharged-v8-enters-production/?intcmp=features

I love my RSTD and I think Yamaha would have a winner in they put the Vmax motor tuned down a little for better gas mileage in the RSTD. The bike has a great engine in it already but with the FI and more power I would think it would sell. What you all think?

I need to borrow/rent an engine hoist / shop crane for a couple of weeks. I was looking at buying one from Harbor freight (on sale now for $180 - 20% coupon + $144) but I really do not have room to store it when I am done with it. I just bought a surface grinder to put in my basement shop and need the hoist to disassemble it, load it, unload it, and then again to reassemble it in my basement. Anyone have one within 100 or so miles of Milwaukee? I have a full size P/U to come get it and return it home in a few weeks when I am done. I have also been watching Craigslist and ebay to find a good cheap one that I can use and then resell when I am done with it.

It's killing me to think about doing another engine swap into my 83/86 Venture Frankenbike. And I'm very ticked off to not be riding the rest of the season. I still may try to get another 86-93ish engine, or another 86-93ish Venture, ride it for a couple more months, and do an engine and plastic swap. But it's stressing the crap out of me. I've read a LOT of adventure rider riding reports the past 2.5 years, and it really intrigues me to be able to go odd pavement on a lighter bike. I've looked at a new Honda NC700 and a Suzuki 650 Vstrom and I'm approved for either one. My wife isn't on the wagon. I'm more interested in the Vstrom. I may try to look at used Vstroms depending on if I can get financing. I'm very interested in the high gas mileage (65mpg); that would pay for over 50% of the payment (new one), increasing my monthly $ commitments about $100/month, and I wouldn't have to touch it mechanically for a lot of years other than normal maintenance. Tomorrow I'm going to go to the credit union and see what Kind of financing I can get for different options. If I do go the adventure rider bike route I will just part out all of my Venture stuff. Sucks that I barely spent almost $200 for a new rear tire. I'm just getting VERY sick of life's curve balls. Doug

Looking at some new needle sets and was surprised at the price difference between genuine parts (like $42) versus aftermarket($17). Any thoughts on the use of one vs the other in engine parts like needle sets?

This morning I was in the middle of replacing my clutch bearing on my 86 engine in my 83 Venture. I took the entire clutch basket out, which is a very good thing. On the very back of the clutch basket there is a gear, it drives a plastic gear on a keyed shaft going through the case. a screw had broken that holds the retaining piece for the shaft, so it was floating. On the other side of the case, where there is a gear on the other end of the shaft, that gear meshes with a plastic gear that drives the oil pump. that plastic gear was stripped. So my engines been running without oil supply probably for 150 miles this week. crap, crap, crap. I need an engine, a different bike, a new bike, ...no money. crap, crap, crap. Doug

So I went on a 6 mile RT with my '88 VR to gas up the bike, and when I got back, the engine was running a little rough, saw no wet spot clue under the bike, so I removed the engine side covers to tamper with the pilot screws to see what happens. On 3 carbs, turning the pilot screw in all the way caused the engine to slow to almost stop, but the 4th made no difference. That meant the one carb was getting fuel from somehwere else. So I shut off the engine and heard a soft Darth Vader type labored breathing sound. Sound did not quit, so I removed the air filter and looking down the intake with a flashlight saw carb in question all wet, and could watch fuel spraying from the needle jet with each of the breathing sounds! What the...? Never experienced this before in 45 years wrenching. Decided to drain the fuel bowl and ran the fuel pump to pressure flush through the inlet valve, and sure enough, there was a small particle that came out. Reassembled and started the bike, sync'd the carbs and adjusted the pilots, and the bike idles fine once again. Just can't figure out what caused the pulsing breathing sounds that lasted so long, as there seems no vacuum source with the engine off. Maybe engine heat was vaporizing some fuel for the pressure cycled release and resulting fuel spraying. BTW, new fuel filter installed a week ago, so the particle likely came from the wrenching environment. I guess it pays to flush everything when fooling with the fuel system. -Pete, in Tacoma WA USA '83,88 Venture

Greetings, Previously I had posted some problems I was having with battery on a trip I had just went on.Tracked problem to r/r. I have searched but have not found any articles how to replace this unit. What I have read I believe it is fairly simple to change and it is on the left side of engine. I was wondering if someone could point me in the right direction on how to do this. By the way the bike is a 2000 RSV. Thanks.

Hi gang allow me to introduce myself, I just bought a new for me 1991 Venture Royale so my wife and I could go touring 2 up. The Venture only has 72,000km so my thought was uhm just broken in. My other steed is a BMW 1989 k100rt with 125,000 km, my wife just doesn't find it comfortable for long hauls so its gonna have to go. Anyhow back to the subject at hand. There is a whiney drone coming from the engine area. The sound occurs while riding, and occurs when I release the throttle and last until the engine revs are very low, it happens all the time at any speed and in all gears. I suspect something to do with the clutch. This evening I removed the presure plate the friction plates and clutch plates, all are within specs. I have not yet removed the basket however I did grasp it in my 2 hands and was able to slightly move it laterally forward backwards and up and down. Here is my question am I right to suspect that the bearing just behind the basket might be worn or damaged as any play in the basket (shaft) doesn't seem right. Maybe worn bearing, side play affected by the torque of the engine compression slowing down the bike? Check out this picture it was taken by Freebird and this is what he found behind his clutch basket notice the bearings, the cage is broken I suspect this could cause the severe noise I am experiencing. http://www.venturerider.org/engineremoval/images/815.jpg -
I have engine noise in headset when intercom is on, the noise will go away if rpms are low enough. any thoughts? I've asked around town here but know one knows a thing including the dealers.

ok i do not ride a venture but i do work at a dealership, small one, like i am the only employee and the other folks own it. I have a weird issue with a venture that i cant figure out. even called yamaha and they seemed puzzled. what it does you can cruise around all day at in town speed and nothing will happen, you hop up to highway/ interstate speeds (70-80) and the bike dies, check engine lighgt blinks twice and then the bike comes back on, no set time period as to when it will do this, seems completely random. owner has removed radio stuff from the bike. I have no idea where to go next -
When I was shooting the Rusty Wallace Driving School this past weekend I also stayed and did a little walking around the pits of the Legend Racing Series. The engine they all have to use is a Yammi. They haul... Radar gun showed 98MPH on the small straights. http://i25.photobucket.com/albums/c66/CNONT/Lengine.jpg http://i25.photobucket.com/albums/c66/CNONT/L19.jpg http://i25.photobucket.com/albums/c66/CNONT/L24.jpg http://i25.photobucket.com/albums/c66/CNONT/L13.jpg http://i25.photobucket.com/albums/c66/CNONT/L8.jpg

First of all, I absolutely do NOT think that there will be a new generation Venture for 2013. All the talk about it got me to wondering about something though. In the unlikely event that there IS a new Venture at some point and Yamaha is actually smart enough to build it around the new VMAX engine, what can we expect in regards to the engine/gear/clutch basket noise. Did Yamaha improve that with the new engine? OK...I addressed this to Squeeze because I know that he has the new generation VMAX but there may be some others that own or have ridden one also. So...I guess you can answer too.

So I swapped a (mostly) 1300cc engine into my bike and now I am left with a 1200 engine that I have no room for. I want to get rid of it, but keep any parts that I might need as spares. The donor motor had no covers, so mine went back on. Same with clutch basket. The motor has been pulled apart and will be heading to scrap soon. This is what I am saving so far: -Starter clutch (good condition, no cracks) -Valve covers -Misc bolts/nuts/washers -Valve shims If anyone has a suggestion as to what else I should keep from it, otherwise I will be tossing/recycling the rest of it: -Engine cases (upper & lower, 1200cc) appear to be in good condition -Heads (from 1300) - they are in rough condition, rusty & stuck valves (don't appear to be bent tho) -Rotating assembly (pistons, crank, counterbalance, transmission, output shaft) ---Main bearing journals have some scratches in them ---2nd gear issue on transmission parts -Camshafts & chains I am basically in the mindset of "I've been in there once, I'm not going back in", so I don't forsee the need of keeping the engine or any internal parts. Plus I'm not really an ebay seller type of guy so not saving parts to sell. -Andrew p.s. If anyone wants the remains for free... -
Today when I fired up the bike it started acting funny it idles fine if i rev it the tach and engine will rise to about 2500 rpm just past 2500 the tachometer drops to 0 and it starts to hesitate. when I ride it it does the same thing it gets to 2500 the tach drops and it will still accel but isnt all there "here is where it gets wierd" if you hold throttle and keep accelerating once the engine gets to about 4500 rpm the tach comes back to life and holy sh*t you better be holding on, because its just runs like a champ till get back into that range. Has anyone ever had this issue before. I am almost certain it is an electric issue. -
i'm getting alot of folks interested in my cushman, which i was'nt expecting. it's for sale but not quite yet. there are a few bugs that i need to iron out before i sell it. here's the scoop. it is a 58 pacemaker. that looks original on the outside almost. it has a honda 390 cc clone engine that is built to the hilt. with a comet cvt automatic transmission. it is electric start, has a custom made hydraulic disc brake in the front, overcize polished aluminum wheels with tubeless motorcycle type tires. it is absolutely gorgeous, and has a $2000,00 dollar two tone paint job. silver and medium blue clearcoat. the bugs i need to iron out have to do with safety. i overbuilt the engine and it is just to fast for the particular model it is. i took it to georgia last summer and had a few close calls in the curves. it will probably run over 70mph like it is. i would'nt want anyone getting hurt. when i get time i want to detune it a little. smaller carb, and stock head. it is very well engineered. i built it last winter and rode it about 400 miles. i put $6000.00 in it not including my labor. i will want $6000.00 for it firm when i sell it. i have folks waiting in line for it that have seen it. i just can't sell it until i have it perfect. that may be awhile cuz i'm bulding an eagle for my buddy so it has priority. i got some pm's about pics i will work on that. every part in it except the frame forks and body are brand new including the engine and drive train.

On the way into work today I pulled up to a red light. Just as I came to a complete stop the engine quit. It just stopped as if I had turned it off. I was in 1st gear and had the clutch pulled all of the way in. I immediately shifted to neutral and hit the starter and it fired right up and never missed another beat for the rest of the ride in. Engine ran perfect before and after. I know I did not hit the kill switch because my right hand was busy braking for the stop.

I went to start my 07 RSV this morning, all dressed and ready to ride. Starter sputtered, making sounds like dying battery. End of ride. Bike has 33k on it. So here're the symptoms that I've measured so far: Battery open circuit voltage is 12.3 after trying unsuccessfully to start the motor. I put it on my charger, and got a green light after five minutes. Open circuit v now 12.8. I put the battery back into the bike and it cranked normally. I measured the v across the battery with motor running. At idle I get 13.7. At very high engine speed (no tach) I get 13.9. It never gets above 14v, and only varies between those two points, 13.7 to 13.9 at any engine speed. Book says should get above 14v charging, up to 14.5. Does this below-14v output, and the fact that it varies only .2v, point to a stator or regulator problem? Interestingly, I had a year-old battery fail, and also spit battery acid out into the battery box, some of which then dripped down onto my swingarm. It was a Westco. I suspected an overcharging situation then, but if anything, my charging output is lower than it should be. The new Yuasa that replaced it four months ago has worked flawlessly until this morning. I suppose the new Yuasa could be defective, but how odd to have two battery failures within four months? One suggesting overcharge, the other undercharge? Erratic Regulator? I'm checking connections now. Thanks for all help.

1985 VR, started hearing a clappy noise at start up and would quiet down after warmed up. i thought it was the "H" Pipe rattle eveyone complaines about and since it was the end of the season I didnt think too much of it. However I have been going to start the bike up at least once a month and letting it reach operating temp before shutting down. This last time I was starting think maybe my clappy noise was engine related and not exhaust. Below is a link to the video I just shot from a cold start and walk around trying to see if I could pin point where the clappy noise was comming from. I am hoping someone here with more experience is able to recognize the sound and tell me if it's exhaust or engine. I am hopping for exhaust as I plan on doing the HD muffler MOD and weld up the "H" pipe in the early spring. Thanks for your help. please use the link below to see the youtube video.

Cutting side covers
johnnydemonic posted a topic in Venture and Venture Royale Tech Talk ('83 - '93)
Hello all, new guy here with an 83 xvz12 I have had for about 15 years now. Great site, wealth of information here. Quick question, I am planning a styling change, based on a couple of bikes I have seen here which I call "semi-bobbed", basically I want to expose the engine more (it's a great looking engine, why keep it covered?) and remove the trunk, etc... Make it look a little more like a fairinged cruiser than a full dress tourer. My question is: Before I cut the side covers down, is there anything I should consider, best method for cutting, tips, tricks, etc? Thank you, Johnny. -
I want to send out a big Thank You to all the folks on this list that have done work on their bikes before me, and have posted the mechanical and technical highlights and info, so that people that follow in their footsteps have an easier time of doing the same thing. For all of you that post info on this forum about improvements, additions, etc., and especially if you include pictures...Thank you. You know who you are, and "I" appreciate it. Today I received in the mail my new Speedhealer from HealTech, and my new Morgan Carbtune Pro, from Calif. Sportbike. Due to the info from trailblazers on this forum, I was able to pre-read all the details prior to my receiving the packages, and was very ready once the items did show up. Now, the speedo on the RSMTD reads accurately, and the carbs are nicely balanced. While the carbs were not too far out, it is nice to KNOW that they are now balanced, and that the engine does in fact run smoother. As a gearhead myself, I want to KNOW the facts of my engine...not just assume. Now, to all you VR and RSTD owners within the PNW, if anyone wants me to ride over to your place and adjust your carbs...for FREE...just let me know. If you want to, you are welcome to ride over to my place...but I am always looking for a reason to go ride somewhere. I will bring all the tools needed, so I will be happy to do the balancing, and show you how it is done. Remember...it is FREE. Thanks,
