Piston for a DS650
#2
I own neihter, but i'll guarentee that a piston/cam and a valve job will improve everything, bottom/mid/and top end. Big imporvment i'd bet. Porting and carb and hell you'd be able to call it "modified" [img]i/expressions/face-icon-small-smile.gif[/img]

To make the right selection for you, I would have to look at a few other factors.
1. When you do your 75% time at the dunes, is it alot of drag racing, or jumping and general riding as well?
2. Are you willing to run 95 octane or better fuel for a little more power, or would you prefer pump gas?
3. The mountain riding you do, is it fire roads or tight trails? [What sorts of speeds do you ride at?]
Besides the 3 choices of cams that I might recomend for a quad, we also have a few different compression ratios for our pistons. These questions will help us figure out what combination will be best for your riding and your motor.

I do alot of mixed riding everywhere. I had a 440ex with 11:1 compression and ran well on pump gas at this altitude. I would probably want to stay aroud this ratio. The cam is another decision I would like an all around cam.
