What are the best mods to put on a preddy, to bump up the HP, and just make it better?

And what can i do to it to make it different from my buddy's, they are both stock at the moment?

 

Start with a good full system pipe, then go with a good intake system.

 

You need to get a new Exhaust first off. But to make it a little different. Go with some graphics from Rathracing. For more HP the exhaust will awaken the sleeping beast. A new carb will give you the low end and more power through out the band. A brand new TRX450R carb will do just that and you can snag one from servicehonda.com for $170. You will need to come up with a new throttle cable and throttle. But if you get a carb from rath or nicholas you will spend $400 easy and have to get a new cable anyway.

 

Go order Doug's CDI box for $158.00, money well spent, unless you have an 05 like me and they are not out yet. Doug's carb mod is also a good choice.
