I have here a low hour 2004 YFZ450. The motor was like completely rebuilt when I bought it from Larsens. I bought it back in 2005, and I hardly rode it much. I wouldn't go out and ride for very long. Anyway, I have taken very good care of this quad, it has been garage kept, only raced 2 times so far since I've owned it. I put about 10 hour of riding on it, I dunno. Here is a list of mods I put on it.
-DG Nationals black front bumper
-DG MX grab bar
-DG Pro Peg nerf bars with blue nets
-K@K e-brake cover
-K@K decompression plug
-steel bolts, nuts, and washer plates
-19x6-10 Holeshot MXR6 front tires
-19x10-9 Holeshot MXR4 rear tires
-Streamline rear brake rotor
-Tag X-5 silver handle bars
-Tag black bar grips
-DR.D race slip on pipe
-Jetted-170 main jet, 45 pilot jet
-NCVQ needle
-Woodward silver fuel screw
-GYTR air filter
-2006 stock steering stem
-bikerman tether kill switch
-MX Revolution reuseable oil filter
-TCS Shocks-stock shocks rebuilt by TCS Suspension
-HEP Silver Lower Race Series Rear Fender Brackets
-All Balls Blue upper and Black lower chain rollers
I am looking to get at least $3,800-$4,000 for it. I am looking at the KFX450R still. Oh, one more mod that I will be putting on the quad is a GYTR Kickstart kit-GYTR Kickstart lever, shaft kit, and starter block off plug. I also have the stock exhuast pipe, headlights and brackets with bolts, and the tail light and bracket with bolts, and the fan, which these will go with the quad. I took that fan off because I'm getting a kickstart for it, and I took out the electric start. Oh and I sent the rear shock out to TCS Suspension, but I'll be getting that back soon. Well, thats about it. let me know if you are interested.
