'87, sat 4 a long time, 14k miles Had issue with fuel in carbs that a $600 injection into the dealers retirment fund did not cure! Flushed w/carb cleaner/blew everything out and then washed with engine cleaner Now no spark at plugs. Backtracked all steps cleaning and drying e/thing, still no joy! Juice at coils though. AND NOT RIDING ON HOLIDAY WEEKEND! HELP!

Well, after getting my '87VR back together I had 2 stuck carb needle/seat assemblies. So I decided since the old girl had over 70k...it was time for a complete going thru of all carbs. I have put 99% of all the miles on this bike. So I know how it should run. I have done carb work many times on many different bikes. So I was not afraid. Jets were removed, jet blocks "dipped". I set the floats absolutely perfect on the bench and confirmed w/engine running. Results have been all carbs give an ideal idle of 2.5ccw low speed screw all carbs. While #1 & 2 cause rpm drop right at 3 ccw. Which is quite normal to me. BUT on #4(rght. frnt) I can go to 5 turns ccw and not cause the idle to drop and #3 is almost the same. Which is not normal to me. All settings done with an accurate digital tach. Carbs are syc'd.All checks for vacuum leaks done. None found nor suspected because... HERE's the real issue. #4 starts to misfire when the bike is really hot, seemingly like too rich. I can hear the spark cap arcing and using a screw driver and my finger(ouch)confirmed this. Wire replaced 2 times, spark plug & cap(stock and NGK) 3 times-no change. The spark plug is not wet when it is removed. But does have a very small brown spot on it. I suspect something like this may be impossble to read w/o that glass spark plug thing(can't remember the name).I honestly believe the new internal gaskets that are now the "norm", don't seal worth a damn. These new cheapo gaskets are very fiberous.I suspect they don't seal well. The originals were hard paper. Does anyone else whose done rebuilds have the same suspicions regarding these NEW gaskets...? My only other possibility is the choke plunger leaking. But this possibility is something I have never witnessed in all my years. Lastly , I used to always get over 40mpg solo... Now it's impossible. No, I am not going to lower the needles. That's not the issue here.

I was replacing the spark plugs on my 97 Tour Classic and in the process of struggling with removing one of the spark plug wires the wire came out of the boot. Seemed to be much too clean of a break; looked like it was cut with a knife the break was so clean. How do these connect within the boot themselves? I am assuming I now have to replace the entire assembly (coil plus wire), correct? Is there any way to repair it? -
Hello all, I'm back to partake from the "Fountain of Knowledge". My 1996 Royal Star developed a "miss" and would backfire. In doing some checking I found that I have an intermitten spark from cylinder #3. This condition exists when the bike is cold or warm that in my thinking would rule out the coils because from what I have read the coils fail mostly when they get hot. Any suggestions?

Recommended plugs that I can buy at Canadian Tire or Auto Value? Replacing spark plugs requires tank removal? thnx

There's a few of you who have read/replied to my thread regarding my '89 backfiring a lot.http://www.venturerider.org/forum/showthread.php?t=45485 I posted a little bit about the no spark condition on the right rear cylinder. I tested the coils, and are within limits, all three other spark plugs work just fine. I tested the spark plug wire installed on the coil and the plug cap removed - got good resistance. I then tested the wire with the cap on and the cap by itself and was having a hard time getting a good resistance value. I had to turn the multimeter onto 200K ohms to get a reading. I'm thinking that the spark plug cap may be the problem. Anyone have other ideas? I've got new wires/caps on order. Hopefully that'll fix the the problem! Has anyone had a no-spark condition before from the spark plug cap or the spark plug wires?

Bought a new-to-me 97 Royal Star Classic. Since I am not sure of the maintenance history I was going to change (among other things) the spark plugs and wires. Any recommendations on what brand of wires, or where to purchase from? Thanks.

Been looking at Tach's for maintenance work. I would like one that works with both the Venture V4 and V-Twins. This is the only one I've found that will do from 1-12 cylinders. It also provides three means of connection(s). What type of ignition system does the 2004 Venture have? How about an 2005 V-Star 1100. A Multiple Spark Ignition System orDirect (coil on plug) Ignition System This is the Tach I'm thinking about. Will it work? I like the Inductive Pick-Up on Spark Plug Wire for maintenance work. Thanks in advance.

whats the best and what gap are you seting them at please???

I changed all my diaphragms yesterday. I also moved the circlip on the throttle jet up one notch away from the needle to lean it out. I did this on all carbs. At several points, I stopped and started the bike. It sounded OK. It idled OK. Today, I decide to change the spark plugs so I can evaluate the new mixture- and discover #2 cylinder spark plug cap was dangleing on the other side so it was idleing on 3 cylinders. I go ahead and finish changing and gapping all the plugs. The dang thing races at 2200 rpm or higher, no matter where I put the screw. The trottle cable is disconnected, as it broke and I got the new cable this afternoon so have not put it on yet. No, the choke is not on. The linkages seem to all be functioning. I do not see any loose vacuum hoses- but i know a leak may be part of it. What to do? I can't sync carbs like this!

I notice after i do something to my bike I read a better way to do it on the forum after i do it, so this time i'm asking. Any special tools or work arounds? should i spring for the irridim (is that like dilithium crystals?) spark plugs? Thanks -
2008 RSV STOCK and serviced at 600 miles by me. Now at 8,000 miles-ish. From Mileage 0000001 thru about 7,000-ish miles got about 200 mpg before Reserve Fuel Light came on. From 7,000-ish to 8,000-ish the Reserve Fuel Light was coming on regularly around 150-ish miles vs 200 miles earlier, that is a 25% loss of mpg. (Thinking to myself Hmmmmm the 8,000 miles Service is soon and then replace (OIL= Shell Rotella 5-40 Syn, Oil Filter, 75-90 SYN in Final Pumpkin and replace spark plugs). These were the same fluids used at 600 mile Service. Had GREATEST of performance enhancement with NGK Iridium Spark Plugs on (Toyata, Subaru, Two Yammie Outboards and Yammie-Rhino-660) using the NGK Iridium Spark Plugs. Threw them in my STOCK 2008 RSV at 8,000-ish and BAM got my MPG back to 200-ish miles before Reserve Fuel Light comes on again... NO LIE So the Owners Manual was DEAD ON in regard to spark plug replacement around 8,000 miles. Hopes this helps someone... NO I'm not a NGK Stockholder or Dealer... Just a decent Mechanic and a simple M/C Rider.

I bought a used 1990 Venture. I went on a trip to OH. I parked it at night, it was running fine. The next day it start skipping and popping. I worked on the kill switch and it seemed to fix the problem. Since I returned home, bike had been running good. I went for a short ride recently, parked it, and it has not started since. No spark! All other electronics work properly. Any and all ideas greatly appreciated.

I came home from the M&E in Rockville Saturday evening parked the bike, I got on it this morning and it won't start. I have checked the fuses and the battery, I pulled #3 plug and grounded against the engine case,NO SPARK. The plug looks great nice and tan, no crud. It cranks just fine, I smell a little fuel, not bad. I'm a rookie so please be patient with me and tell me where to start looking. I'm going to go to town and get 4 new plugs while I working on it. Just when we get cooler weather, this stinks!!

Hey Folks, Dave Pankow can't seem to get a break with his 1st gens. I am helping him work on a no spark issue and it's looking like it's a TCI or in his case being a '90 VR a DCI. It appears that '90 was when they went to the different control system for the spark, so anything before '90 wont work on his bike. MICarl has been helping us with this problem and is of the belief also that this may be the culprit. What I need to know if some of you pack rats out there have a good spare TCI (DCI) that we can test his bike against. This would only be to verify if in fact this is the problem, if anyone can help him out it would be greatly appreciated. You can PM me or Dave (Jus monkeyin around) and let us know...Thanks in advance

Okay, I bought new plugs for my 87VR. So I could check how the bike is running, clean or not? Well after 500 miles on the new plugs I got some misfires at idle when hot. Like when doing a carb sync. or setting the low speed screws w/digital tach. 1st let me say I did all these same things 2 month ago w/old plugs and had no misfires. Now I decided to check everything before getting ready for Americade next week. I have new spark plug wires and caps as of 4 years ago . The misfired showed up as a loud tick coming right from the spark plug cap of #3 & #4 along with a skip or drop in rpm while simply idling, which shows clearly on my digital tach. I changed the spark cap...no change in problem. Then changed the spark plug and problem gone. The plugs removed are clean, not fouled. My low speed screws for all cylinders when adjusted show an obvious "sweet spot" varying from 2.25 to 3.5 ccw. Not trusting these new NGK DPR8EA-9 plugs. I now have all my old NGK plugs back in. I may try to get non-resistor DP8EA-9. Fact being, it's normally the resistor element being faulty under extreme heat that causes the issue. I do not like iridium plugs as the electrodes are very sensitive and should not be touched by even a gap gauge. I guess even Japan is making crap these days...Anyone else had similar problems like this???

How do you change the spark plugs on a 2006 RSTD?
-
Go figure spent all last summer rebuilding my bike after it got smashed up. Had two good rides out of it before parking it for the winter. yesterday. I changed the oil and filter fired it up to go for my first long awaited ride for the seaso and wouldn't you know it, an engine miss put my hands on the exhaust pipes and the left front one is stone cold , YUP a dead cylinder I put a spark tester in line with the plug and opened the gap to test spark strength and was over 1 inch and still getting strong spark jump across the gap. pulled the plug and although it was black it was not wet like a misfiring plug would normally be. going to do a compression test todayand see what my compression is. I sure hope it isn't some delayed damage from when the bike went down.

well im having trouble with my 83 venture xvz12 it wont start ive changed the tci checked the picup coils and omed out the coils and they are all checking out fine but still no spark can any body give me some thought of what i could do next

Please oh great and wise ones... I'm going nuts here. About two months ago now I got stranded at work on my 99RSV. Rode to work just fine. When I went out to start it to go home, the starter turned and turned but she wouldn't start. I pulled the two back plug wires (cuz I could reach 'em) and stuck a screwdriver in there. No spark. I got the bike towed home and checked the other two plug wires. No spark there either. Checked resistance to the coils, and I'm easily within specs. Same on the batt'ry voltage. I then skipped all the other smart things to do and ordered a new pick-up coil and gaskets. After installing the pickup coil, the bike started!! Unfortunately after I shut it off, I could not replicate the victory and it hasn't started since. Well... I'm too much of an idiot to admit to my co-workers that I don't want to ride cuz it's just too darn cold, so I've been using the excuse that the bike ain't runnin' as my out. I'm now starting to get that twitch in my eyelid from driving the cage to work for two months and have decided to re-enguage. Any ideas? I'm gonna try to bypass the Kickstand and kill switches tonight (there's no need for anyone to remind me that I should've checked that before buying a pickup coil... my wife has that covered) but I'm not hopeful. any suggestions? thx! -
no spark to front cylinders any ideals?
Guest posted a topic in Venture and Venture Royale Tech Talk ('83 - '93)
newbie to this baord HI! ALL . i have a 1983 1200 with a 1300cc motor on it was a members bike from canada anyway i ran when parked last year had to go through carburetors it runs good on back cylinder but no spark on front one any ideals? thanks mike -
OK, I tried out the Colortune yesterday, and I don't think I am impressed at all. My plan was to use the Colortune on one cylinder, then compare the CO % of that cylinder with the others using the exhaust gas analyzer. Since I cannot find any published specifications from Yamaha for the right CO level on this engine, that seemed like a good way to approach it. The problem is that the Colortune does not seem very specific. I could turn the fuel mixture screw a LONG way in either direction without seeing any change in the color of the flame. After turning it out a lot I did eventually see a yellowish flame as I should, and if I turned it in far enough I would eventually see it begin missing a lot (mostly just a weak spark), but there was a huge range between those two points where all the sparks looked the same. I eventually just turned it in to the ultra lean point, then turned it out just a bit past where the spark seemed to be regular without any missing. The interesting part was that when I compared this setting with the original position of the mixture screw, it was almost identical! Coincidence? I have no idea. One other problem that may have contributed to the lack of a clear setting was that the spark was constantly jumping from the top of the Colortune plug to the engine, potentially causing a lot of misfires that would affect what I could see. But since this engine seems to have a dual-fire ignition with a waste spark in every cycle, there is no way to be sure how many of those arcs were really causing a misfire. I was doing this inside my garage on an overcast day where I thought the light was about right to easily read the Colortune. In addition, I was working on the left rear cylinder where it was very easy to look right down on the plug and get a clear view of the spark without needing to use their mirror attachment. Finally, I purchased the 12mm Colortune specifically for this bike instead of the generic 14mm unit with a 12mm adapter. I am glad I did this now, since the 14mm with an adapter would have had the Colortune plug sitting much further out of the cylinder, and I would be wondering if maybe that was why I found it so inaccurate. I have not yet tried out the exhaust gas analyzer, but I'll let y'all know how that goes soon. In the mean time, I would be interested in any responses from others that have actually used the Colortune. What did you think? Goose

I have a 86 venture and the problem is I can't get spark returning to the spark plugs. Myself and Dokon have replaced the coils, plugs, the tips on the wire into the plugs, I think it is called the ignition coils ( what goes under the battery box that the coils plug into). We have tried everything it seems we get spark going on but coiming out we get nothing so the bike won't start. Took it to my bike mechanic and he again replaced the coils which I told him I already replaced. He told me that was the problem since no spark was coming down to the plugs. Well he fried the replaced ignitor box and I guess the circuit box in it. He is now stumped and said he doesn't know what it might be and I might have to use it as a part bike. Go figure I only have 100,000 miles on it so I am asking if anyone has had this problem I don't want to park my bike out I love it. He said they only other thing it might be is a bad short on the bike somewhere. Thx, Meatloaf:crying:

I have the do-hicky that came withmy '06 Tour Deluxe to remove the plugs...is there supposed to be a wrench that somehow fits in the space in the cylinder to fit on the spark plug socket and actually turn the socket? The manual showsa pictureof something thin that fits into a hole in the side of the plug socket. ??????????????? Can somebody post a picture of what turns the plug socket that came with the bike?
