OK I think Its time for a new piston for my 2004 dvx. I am wondering what pistons you would suggest for a stock bore, and what compressions ratios you would suggest? Any info is appreciated. Yes I have searched too, and couldnt find what im looking for either. Thx for any posts!

 

If you are gonna change the piston, just get a big bore kit and go to 426 or bigger. There is no point in doing it unless you are gonna give it a real power increase. There is no subsitute for cubic inches, or in your case cubic centimeters.

 

yep, like bear said, there's no replacement for displacement! You'll have the cylinder off and you might as well bore it out. Wiesco is a good piston though.
