you need shims for the rockers

why do you need shims's

[benwa450r]

DON'T overtighten 3 valve cover bolts. They will snap very easy.... I know. Valve adjustment is done by replacing shims on top of valves. Make sure to use high-heat lock-tite on cam sprocket bolts. Als check clearance on decompressor. Do a search on valve adjustment on this forum for more information. Good luck.

i need shims for the hrc cam and how will i keep the timing? does it need to be advanced or not? ..........any other tips

[benwa450r]

You may or may not need different thickness shims. All depends on the clearance after installing cam. Go to "TRX450R.ORG" and go to engine faq section. Theres instructions and pics that may help you install cam. There's alot of technical info. there. Just look for it. Hope this helps.:)
