What should I do

Right now In Colorado it is the end of the season, and I am ready to do some major eng mods. I just read the info on the Big Gun system in Dirt Wheels yet I don't really know what to do. I was woundering what kind of things you people have done to your bikes and would recommend it. To add to the fact I am trying to keep up with a mod YFZ450(booo) and a 686 Raptor that is really built up. So any info would help. Thanks.

well we need to know what you are wanting to use it for.
drag?
MX?
hillclimbs?
TT?
XC?

if people know what you want to use it for they can give you a better sugestion.

Oh sorry, I guess that would help a little, I would like it for drag racing, maybe something with a 4" swing-arm so I can still use it in the sand to kick around a little.

For drag racing you are going to want a higher compression piston, head work, exhuast, and cam. Its all about breathing.
