I went and rode a dirt bike for the first time 2 weeks ago, a '05 KTM 525, and was instantly hooked. I looked around and picked up a '99 WR400 this sat. Its has most of the little tricks done to it(airbox cover gone, gray wire, new header and pipe). It also has a power now air intake, a Zip Ty(?) mixture screw, and protaper bars. I rode it on sunday and love it . Is there anything else i should check that could pose a problem on it.
