Hey Guys - I am new to this forum, but have been on ATV's since I was 13yo.I am now 40.I just picked up an 88 TRX250X for my daughter to go riding with us.Needs a alot of work, but for $300 I couldnt pass it up. Anyway, it has quite a loud rapping noise in th very top end.I dont think it's the piston slapping, although it could be, but I suspect the cam bearings are gone.Either way, I was wondering if someone knows where I can download the manual online for free, like I did for my Yamaha Grizzly. If not, can anyone send me the pages of the manual that cover everything from the jug up to the top of the engine ? I really need to know how to get the timing right when I reassemble it, and the torque specs.Any input is GREATLY appreciated! This thing still runs like a top, starts first kick every time. I have been a member of several forums for years, and the knowledge is unbelievable.Also, I know the 300ex is almost identical in many ways. Is the engine the same? What are the known differences? Again, thanks for any help or advice! :icon_ rocker:
