    04 Yamaha 800XLT

    Alrighty I have a guy selling a 04 Yamaha XLT 800. Thing has 90hrs on it, looks in perfect condition, no leaks in engine bay. No signs of it be capsized or water being in engine area. Guy says he hasn't drove it for 2 years, he cranked it up last year started fine. He drained the gas out of it before this past winter. I plan on running a compression test on it tomorrow when I test Drive it. What else should I look for before handing over the cash to him? Whats the exact Compression PSI should I be looking for on the ski.

    Awesome, did a compression test today. rear was 120, front was 150. Is that cool? Also it was smoking just a little from back ride. Guessing thats just exhaust side hitting water? Doesn't cloud up outside of water.

    did you have throttle wide open while doing test? Was the other plug in or out? Something is wrong usually if the gauge is a little off both cylinders should read about the same though. I would check again and make sure to have both cylinders close to the same values.

    I had Throttle wide open! I tried with other plug in and with it out. It was having trouble getting to 120 as well. I ended up not buying that ski! Didn't wanna take the chance! Thanks
