A decent pair of shocks, a good set of tires, take off the lights (if it has lights). Not much else needs to be done.

Make sure the bike is solid and reliable. Go through the bike thoroughly, checking for worn parts.  Ignition, compression and carburetor make it go, the rest let's it roll.

Kevin,

Still keep tacking issues #15, 16, and 17 document how Kent Knudsen preps his championship winning Pentons for serious competition.  They go through all the frame, suspension, and engine mods used on the bikes of Kevin Brown and Gary Roach.  I will agree with Brian and Pete, that the best thing you can do is set up your suspension and maintain the bike properly.  I've done most of the things that Kent recommends, and they are overkill for me (I'm not that good [:I]), but I enjoyed having them done, anyway. It's all in the name of fun, so have lots of it!

I have a copy of the porting and pipe specs. that work wonders on that bike, proven by Carl Cranke and many others. Send me your email address if you want them.
