Clutch rebuild question

[jimmyenglish]

Hi all, my clutch is starting to slip. It' been along time on the current one (90k and pulling a 440lb trailer for 40k). Googling around it seems the vmax and venture clutches are the same. Is this correct? Also, is it just a matter of swapping in new plates or should the springs be changed as well? Is there any advantage to the Barnett 6 spring type? Thanks in advance and great forum as always!

Hey John,

With 90,000 on the clock, you have done much better than most as far as your clutch is concerned! Your 86'VR was the first year of the single Clutch Diaphragm Spring instead of the 6 compression springs in the MKI bikes which were built from 1983 to 1985. As long as the 7 steel Clutch Plates are not scored, or burnt up, (you will know this because there are a series of wear dents in the plates, if you can still see the dents, then the plates are still good) then you will only need to replace the 8 Clutch Friction Discs, and of course the Clutch Diaphragm Spring. Barnett makes an excellent product, and converts your single Clutch Diaphragm Spring back to the older style, 6 compression spring type of clutch. Mike at PCW Racing offers the Heavy Duty Single Clutch Diaphragm Spring Kit and I also offer the Heavy Duty Single Clutch Diaphragm Spring in a kit for the First Gen. MKII Bikes here:

And I offer the remaining 7 Genuine Yamaha Clutch Friction Discs in a kit here:

Either way you go, make sure you that the Barnett kit comes with 8 Clutch Friction Discs, and for extra gripping power while towing your trailer, I would replace the 1/2 friction disc at the rear of the clutch pac with a FULL clutch friction disc. (If you get the Full Barnett kit, it will have 8 clutch friction discs, if you purchase the kits I offer in the classifieds, it will have all 8 Clutch Friction Discs as well. If you find that the steel clutch plates are burned blue, or the dents are worn off, they can be purchased separately. (These steel clutch plates are NOT offered in either the Barnett kit or the one I offer in the classifieds)

Shipping to Germany would be extra for any of the kits you buy from either source. I am willing to collect ALL of the parts you need and ship them in one box, with a minimum of shipping cost. I also include complete written instructions with color pics of the clutch install.

If you have any questions about the above information, please feel free to contact me.

Which ever way you choose to go John, Good luck with this project!
