Got an 05 Crf250 and I'm thinkin about a big bore kit since im now ahem, Vet legal. Any one have any experiences?
If you just put a big bore on a stock head they're usually slower on top. The stock head doesn't support the flow requirements of the larger displacement.
I always talk my customers into having porting done first... they always thank me later.
