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.
Thanks. Wat r da cons, other than highr fuel consumption. That's not a big concern at this time. Wood they require additional head work and flow with da HRC cam?
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.
Ill wait till mon to talk to KPS bout da head work he's doin to c if I can go with da ovrsizd valves. I wood rather pay $4.00 for a jet than $700.00 for an FCR. Lol
