Valve Kits / Top End Rebuild Kits

[nomad]

I'm just wondering what kind of Valve Kits and Top End Rebuild kits you guys prefer. Thanks!

Kibblewhite valves/springs and je piston kits

I used this kit to rebuild my head, it's of pretty good quality for the price.

I also second the JE pistons, their just a bit better than the wiseco ones.
Then for a cam, I would just stick with a stage 1 hotcam.

Thanks guys. Does anyone other than Yamaha OEM sell an 83.5mm piston that you know of? Will I have to do anything special if I go with an 84mm aside from boring the cylinder?

When I get ready to rebuild my head I'm going for the KW valves and HD springs. I already got a JE piston kit. IMHO you can't go wrong with either one.

Awesome, thanks!

I have the Kibblewhite valves & HD springs with a Wiesco .040 piston. Great combination.
