Man Mike I hope this quad works out for ya with all the R&D/$$$.
If it don't though put that sucker in a dirtbike frame!
Just so you know the Yamaha Banshee takes the same clutch.
Might be a lil easier to find + more options out there for ya.
You can also mod a Shee pancake bearing to fit.
I have personally welded the ball to my clutch rod so there might be a time when you will need that mod.
I can also hook you up with the part# for a nology coil that will be a nice upgrade in the future.

Cool, did not know about the shee clutch. I found (and bought) a EBC DRC Clutch Kit with plates/fibers/HD Springs though I:I

I'm restoring a 1992 Yamaha WR200R as well, man this 500 would be SICK in there if for some reason the quad doesn't work out! But that would get me way off track with the goal of that bike lol.
 
Is there just no need for the larger studs on the 7 stud head? Won't going to the larger studs allow you to hit the torque mark without nearing the wring-off point of the studs?
 
no need. you don't need to crank the nuts down as tight on them since theres more points for tightening. over-torquing[to prevent leakage] on the 6-bolt heads without modded studs usually made them snap

Mike what size are the WR's head studs 8 or 10mm?
 
they're 8mm like the older ones. the reasoning that i have foubd is that since the load is spread over 7 studs instead of 6 you do not need to mod the studs to prevent leakage. and they are closer together so there is a better clamping force to hold the head and gasket down properly
 
True. That's why Suzuki went from 6 to 7 studs in the LT500.
I wouldn't mess with it unless you find it leaking.
After you get it running and beat on it a lil just post up a pic of the headgasket and the piston at TDC.
I'll be able to tell if it's leaking by looking at it.
 
My 500 is the 7 stud design. The studs have been upgraded from 8mm to 10mm and I also run a copper head gasket. I'm pretty sure I won't have a problem with the head leaking.
