Venture Max HD Build

[luvmy40]

I also found that adding some Lucas to the oil helped smooth the shifting and made finding N a bit easier.

Careful with additives,,, they can make the clutch slip and they are hard to 'wash' out.

Hi All

I have done some research and I am going to give the seafoam in the Crankcase a try, I have T5 rotella in the the crankcase now so I have added the recommended 1 oz per quart then will run the bike for 200 miles then change the oil before my trip, the plan was to put some miles on the bike to work out any bugs that crop up before the trip and change the oil to flush out any dirt or crap that got in the block while I had it all apart, Normal practice after pulling apart an engine.

The engine only has about 37000Km so there is not alot of wear but because it sat Idle for so long there is likely some gumming of gears which should loosen up with some movement with fresh oil.

I had inspected all the clutch plates and frictions and they were all at the thickness of new plates plus I swapped the 1/2 disc and added the HD springs so I am thinking once i get the Transmission working thru the gears it will loosen things up.

the forecast is looking good for sunday and next week so hopefully I can get some miles on it. 

I will update before the trip and try and post while in Laconia. We are there from the 15th to the 20th.

Have a good nite all

Herman

I have to say, I have sat on gone thru this post this evening and I am most impressed with this rebuild write up. I picked up an 89 a while back from the pay it forward forum. Had every intention to rat it out. wound up with some more surgeries over the past few years. When I finally got released, had grand kids dropped in my lap the same week. that's been 3 yrs. This morn a brother from my Motorcycle Ministry came and I paid it forward to him. He has plans to rebuild it back to a running Royale. I believe he can succeed where God had me to stop. That bike looks fantastic Herman. You will have that to be proud of for some good time now. I am getting to doing a batwing on my RSTD have it in the paint process now. I will have it mounted to a set of the quick release arms. Nothing like what you have done here but I have been taking some pics along the way. That was another project that's been on hold for like 3 yrs now. I will do a little write up on that with some pics when I get it done. God Bless you and Keep you on your travels with 2 wheels.

Hi Everyone

I finally had the Bike out for its maiden voyage today, the bike is a dream to ride, very responsive and very comfortable with the new Handlebars and Forward controls.

Only issues I had was I almost lost my Shifter Linkage, It had loosened off and was literally on the last couple of threads on the shifter Side so it appears I forgot to Tighten the 2 Jam nuts or did not tighten them enough, I am glad I Had brought a few tools with me. 

The second issue is a slipping clutch, which I am bit shocked as I had upgraded the 6 springs to the Recommended Harley springs as well as replacing the 1/2 disc with a full disc, one thing to note is most of you who have updated their clutch by replacing the 1/2 disc commented that the clutch was a bit stiffer to pull I do not feel this is the case with my Clutch so maybe I missed something during the re-assembly.

I had not replaced any Frictions or steels but did verify the Thickness with my caliper and they were all at the upper Thickness so I figured they were good,

I had soaked the Frictions in Oil overnight before re-assembly, My only other Thought was maybe I should Have ran Dino Oil for the first Oil Change instead of T5 Rotella which Semi Synthetic.

Upon arriving Home from the 100Km run I did get a low oil Indication,  would this have caused the Clutch slippage?

I had checked the oil before leaving and was 1/2 way between the marks as recommended but had to add a little more than 1/2 a Litre to get it back to the 1/2 way between the marks, there are no Oil leaks so I can only assume the few times running the engine on the Lift was not enough to fully fill the oil Passages and filter.

The engine Likely has not run in 15 years and I did pull it apart to replace all the Seals and gaskets.

I am on vacation for the next couple weeks and heading to Laconia on The 15th so I will be out riding over the next couple days to work out any kinks and to do some Final adjustments on the Single Carb so hopefully the Low Oil was the cause of my Clutch slipping.

worst case I pull the Clutch Cover to re-confirm the Clutch configuration.

Any Thoughts let me know

Thanks

Good Nite

I would change the oil to something designed for diesels. You might have got some friction modifiers into the crankcase and that would be bad for a wet clutch. Not sure about the Harley springs, but would suggest to go the Barnett route.

Rotella T5 is a synthetic heavy diesel oil.

 

OP,

it's possible that those clutch discs were previously soaked with non deisel oil. As Marcarl stated, standard automobile motor oil has friction modifiers and detergents that are bad for the clutch friction plates. And, hard to counter act. They may be toast even though they measure correct.

[HermanK84VR]

Hi Guys

Thanks for the replies.

From all the Oil discussions on VR  I should be good with any Diesel Rotella T4, T5 or T6 unless something has changed in their oil formula.

The Frictions were soaked in Royal Purple Motorcycle oil also a synthetic blend.

With regards to the 6 Springs Earl suggested the Harley Springs as an alternative to the Barnett Kit since I had the pressure plate from the 84 already.

I will have it out today,  worst case, if it is still slipping, I will pull the side cover and yank out the Clutch and recheck everything, I still have a full set of Steels and Frictions from the old 1200 I can swap in and give it a try. I still have a couple days before my Trip LOL.

 

Thanks

Hi Everyone

So I pulled off the clutch cover today to try and sort the issue with my Clutch slipping. here is what i found.

When I put the Engine together I looked at the 2 Clutches Boss that hold the Clutch steels, the part number stamped on both was exactly the same 26H00S01. so I did not look any closer to them at the time and figured i was good to use the 1300 Boss with the 1200 Pressure plate.

Obviously I probably did not put them side by side until now, so as you can see the Clutch Bolt Standoffs are flush with the 1200 Boss whereas the 1300 Boss these same Bolt standoffs are extended about 10mm past the Boss. as you can see in the pictures.

Completely My fault, but it should be good now as I feel more pressure on the Clutch lever now.

I also rechecked all thicknesses of the frictions and the Steels, the frictions all measure 3 MM and all the steels are roughly 2 -2.2 mm and the Factory Dimples are all still there, so I should be good.

Test drive again tomorrow

Hi Everyone

The Day is Here, headed to Laconia tomorrow morning The bike is working Great now that i have the clutch sorted out 

I will post how things went when I get back

 

Good nite

Hi Everyone

Made it to Laconia and Back, The Bike worked Better on the return trip than on the way down which is to be expected since the Engine probably has not run in at least 15 years. The only Issues going down I lost power to My Headlight Circuit , I ran a temporary feed to the Hi Beam to continue,  I eventually sorted it out once we got to the AirBNB, the wire got pulled out of the Crimp on the Fuse block, I re terminated and all was good.

The single carb worked well and I made adjustments along the way for the Mixture and Idle. it seems the sweet spot was above 2500 RPM, below that it seemed to lug in any gear and that could be the difference in the Cams of the Vmax. for the most part I was able to cruise around in 4th Gear thru the Mountain roads and the Kanc at 80 -100 Km /hr and RPM was between 3000-4000RPM.

It seemed the Bike was struggling at 4500 RPM so I kept making adjustments to the Carb Mixture and it now pulls to 8000 RPM, and seems a bit more responsive, it is not near the response of the CV Carbs but It was not my intent for the Bike to be a racer, it was built for reliability and cruising comfort, that being said I think I still can make some more improvements on the Carb by swapping the jets, so I need to source those thru some VW forums.

I did not bother to check the fuel consumption on the way down but did keep track of the fuel and Km on the way back, when I crunched the Numbers it came out to roughly 32 mpg. One item to note and this likely contributed to the lower than expected fuel mileage , while cruising my Temp never went higher than the very bottom of the normal range but while stuck in Traffic it would go up but did not go any higher than 3/4 in the normal. This being said when we would come to a stop The carb would be on a high Idle, a couple cracks of the throttle and it would settle back down to normal Idle, I am thinking the Electric Choke is cooling off enough from the rush of air than causing the choke to come on. I may disable the electric Choke and go back to a manual pull cable to see if it fixes that.

While Cruising around Weirs Beach and Meredith we got stuck in Traffic on some of the Larger hills entering and leaving the areas and at one point I lost my Clutch, It appears I had not got out all the air, a quick bleed on the side of the road and the clutch operations was restored. On the way home I did notice my clutch was starting to slip again but only in 5th gear while going up hill, so I may order a new a set of frictions and steels this winter.  being stuck in traffic on the hills definitely did not help.

The only other issue I had were my front fork seals " All Balls racing Fork seals"  started leaking after I hit a pot hole at about 10KM/hr at first I just thought it was a one off issue but then we noticed spotting on the ground and Fork oil dripping off the Calipers, thankfully it happened towards the end of the trip. The worst thing is the original seals were not leaking I only changed them because I had the forks apart to install the progressive springs, so this will also wait till this winter.

Here are a few Pics of the crew at different areas and we actually was able to cruise thru main st but as you can see parking was all full.

Good Night all

Herman,

I've really enjoyed watching you build your bike.  I think it looks awesome....  Thanks for posting it here... especially for us guys who don't have the knowledge / talent to do such a thing.  I really love how you combined the Harley and the Yamaha parts..  GREAT JOB

[HermanK84VR]

Hi Guys

Thanks again for all the Positive feedback, the bike is running better everytime I take it Out.

I have sourced out some Jet kits from a VW Performance supplier in California so I will be ordering some Main and Pilot jet assortment kits to dial in the Carb a bit better but so far it seems to be running pretty good even with the Mixture screw turned out an extra 2 turns, Midrange and towards full throttle is responsive when above 2500 RPM I am getting some stumbling when below 2500 RPM.

On the trip down to Laconia I was getting some engine Vibration above 4000 RPM this has dissipated and now the Vibration only occurs at 5500 RPM and up any engine speed below 5500 is smooth and no vibration. I have been running this bike as if it was a complete engine overhaul and in the Breakin period, so Gradual increase in engine speed with intermittent bursts at high RPM, I am nearing 4000 kms on the oil so likely will be changing the oil sometime this week, and I suspect I will see some Carbon deposits in the oil, seafoam in the crankcase will go in tonight to help loosen up whatever remains in the galleries and Ring Grooves.

Now that I have been able to put some mileage on the Bike I have to do a couple small modifications or repairs.

Order Yamaha fork seals and replace this winter

Order new Clutch Frictions and replace this winter

I will need to Modify my Floor board mounts a bit as the rear Mount is lower than the front and I have been dragging in short 90 degree turns and on traffic Circles, a quick fix with the welder and a cutoff grinder. With more rain in the forecast I will likely get this done one nite this week.

I will need to source some new signal light switches as the Harley Controls I put on do not latch the signal light circuit or Cancel so for the interim I added small timer boards to latch the signal lights for 15 secs then they auto cancel, works fine but sometimes even the 15 secs is long especially on lane changes.

I have been experimenting with the Air suspension to see the difference in ride and Handling, and because of the dragging Floorboard mounts I have been using the Mid High settings more, with the Misses on the Back I tried the leveling and first set both front and rear to High, no more dragging the floorboard mounts but found the Handling was terrible to the point of uncomfortable in the turns and a heavy feeling in the steering. I now have no air or low setting in Front and Mid to High setting in the Rear, less dragging but still an occasional scrape but steering feels Lighter and more natural in the turns, so this will likely be my preferred air settings.

That is all for now and must get back to work.

Good Day all

Hi All

It has been awhile since my last update so I thought I would give you all an update on how the Single Carb is working

The summer and Riding Season is nearing the end for this year in my Area, cool evenings with Foggy mornings and summer temps during the day, and unfortunately I am still a working stiff so Riding time is limited.

Went out yesterday and toured the countryside with the misses and my 3 riding Buddies to check out the fall colors. 

The Bike ran better than ever so I did a Mileage check, we ran 212 Km before I filled the tank, the Guage was fluttering on the last bar and the warning light flashing when I pulled into the Gas Station, I filled up and it only toke 15 Litres of fuel of the max capacity of 20L, doing the calculation that works out to approx 39MPG,  not bad for 2 up riding, a combination of Highway , secondary Highways hills etc. the VW Pict 34 is working great, I am still running it with the Electric Choke active, I know I am running on Choke occasionally as when we get to a stop sign the Bike is on a higher Idle and I need to give it a crack or 2 of the Throttle to get it back to an Idle. Although I liked the concept of the electric Choke I will be going back to a Manual cable Choke to help improve the Fuel Mileage, between this and re-jetting it will be a different Bike next year.

Due to all the rain we got this summer, I have not taken the time to correct the scrapping floorboards and decided to leave this for the winter so I did not take away from the few good riding days we had , same holds true for the Leaking front fork seals. 

The Kenda Kruz K673 tires have performed awesome through all riding conditions including a 6 Km Gravel stretch of Roadwork we went through yesterday, anyone looking for an inexpensive Tire these tires are for you a set of Front 71H and Rear 77H at Revco.ca here in Canada delivered to my house for $260 Cdn plus taxes.

With Regards to the Air suspension settings I have found the ideal settings for me as most here suggested no air up front with the progressive springs and for the rear  Medium when Driving Alone and High with the Wife on the back. again this may change once I get more lean angle and no leaking front forks.

needless to say I am more than pleased on how the Bike running and I am enjoying the comfort everytime we hit the road.

Have a good night all

Herman
