I have a 2001 DS650 with full step up LTE dual exhaust, BIG Gun Rev Box and piggy back K&N. Most of my friends have Honda 450R's and are starting to get into the motors. They are finally catching up. lol I'd like to do some motor mods to keep them shut up.

I'm wanting to do a high compression piston and cams. I do a lot of dirt drag racing with my friends and occasional dunes and trails. What should I do?

 

Depending on your budget I would go with an OMW piston, 3 or 4 cams and a 48mm Lectron with port matched intake manifold, and an OMW 9 disc clutch and springs.

I started out with this on my DS and it was a pretty awesome power increase over stock.

A 30 shot of N2O should do it.
