whats the best big bore PV?

[krazykarl]

Hey i got a 87' R that i need to do the top end over on. i was wondering what big bore PV kit is the best for trail riding and sand? I would like to stay under a 330. Also if anybody had any experience with them and hows the power delivery. I got a PV on my GAS GAS 300 and the power delivery is smooth. wondering how it is on an R? thanks-Karl

for trail riding probably get a 310 kit but if i were you id get a 330 just because if you want the power its there.

but im not sure about the powervalve i know that the powerband is a lot smoother like a 4 stroke so i wouldnt get a pv id go with a regular bore.

go with a 330 PV, the reason the powervalves are so great is that you can port them for top end and still have gobs of bottom you can make the 330 PV a 350/370 killer that are mildly ported
