Bought an 03 in a crate...... Well, Its alive and it friggin Rips!! OMG now thats power! Well head work @ www.motoxtech.com cleaned up cam journals, new valve, 5 new seats... good as new. Hinson clutch basket, better than new. This motor is amazing, but mine makes a stange noise, maybe from the stator? I think that because there was some wear on the wraps of wire on the stator. and the flywheel weight, ( 9 oz, i think) has some wear, scratches on the inside. (also found a staple when i took it apart!) So I used the stock flywheel, which looked as good as new. I hear the noise at low rpm, a whirring, almost clutch chatter kind of sound, BUT I hear it on the left more so than anywhere else. once past 1/4 throttle, it is gone or just not loud enough to hear. ANY OPINIONS ----Please. Other things I had to fix on my E bay buy... (Not comnplaining.... just a warning, be cafeful what you buy! So far I'm at about 3600-3700, for an 03, so I'm happy, but) subframe, bent about 1.5 - 2 " to the left, but muffler still clears tire..... 2x 4 = fixed The cases had no alignment locating pins!! $3.00 oil filter cover - no o-rings $1.00 the gear that drives the oil pump, THIS IS THE BEST!!!! had no bushing inside the gear!! shaft... 12 mm inside of gear minus brass bushing, a little over 15mm = very little oil pumping. also.. the gear bounced around enough to almost remove the rivets from the back of the stock clutch basket new gear, shaft circlip... $35.00 and ten minutes on my lathe to make a spacer .050 to make up for lost Al. bent and cracked oil screen in frame, With some crappy glue to try to stop the leak. no o ring at the motor where the oil returns from the frame! I am very glad I bought this bike, she deserves better that she was given. I promise to take care of her! SOOOOOO, I'm wondering about the funny noise..... I guess I would say it sounds like a wire brush rubbing lightly on the flywheel?!?!?!? I will be taking her back apart, and will report anything I find, but I always love the Knowledge of TT Experiance.
