I'm rebuildn my motor. On my 05 trx. Cp 94mm 13.0:1. Falicon stoke srtoke, porting by KPS. HRC cam, Alba race exhaust. I'm gonna use Knibblewhite valves an springs. DO I WANT OVERSIZED VALVES????? If so, y? Thanks for any help. I appretiate it.
Any time you add bigger valves there will need to be head work done at a machine shop. You dont want to go to big because of the chance of cracking the head if it gets too hot. You may need to get a different st of rockers as well.
