[Bo Duke]

Just picked it up for 2 grand, just got rebuilt.  Its got Nerf bars, Racing slip not sure what brand and it came with a brand new in the box K&N filter for it and a jet kit....  I'll get pics up as soon as i can, Does anybody know of any lil tricks or tips with this motor to make it faster?  I already plan on re-jetting it, putting the K&N on it, and getting a new CDI box and coil....

Yeah i know how to make it faster.........JUNK IT AND BUY A YFZ450!!!!

[ME OFF]

put the xr 400 dirt bike cam in it 11:1 compression piston and a port job,rev box and you will be able to run with or beat the 450s.i know ct racing makes good pipes and so does hmf.i am still running my stock coil i tried a nology setup and it sucked.if you have the fly wheel lighten it will rev out quicker

anything can be faster then anything it is a matter of how deep your pockets are and i think alot of guys that talk big about factory machines
dont know much because they dont have the tech in there head to build a bad machine you know the saying biult not bought hits it right on the head just my 2 cents

[Norm Henderson]
