    XTREME CR TRANNY MOTOR! CRF50 PATTERN! LIFAN 142cc MONSTER MOTOR PORTED THE WORKS!

    Started as a lifan 120 monster engine.

    TB 57mm piston, cyl., rings, tb cam and sprocket, vm26 carb, ported head, trx90 hd clutch springs, trx90 detent spring, updated shift star, head vent cap, lightened flywheel, and aluminum oil slinger, chrome covers. Also has a tb shift shaft in it so the shifter will clear the ignition cover. It will include the shifter and clutch cable also. This engine doesn't fall out of gear and miss gears constantly b/c the spring and star have been replaced. Very low hours. Less than 10.

    It would cost you at least $900 to build it. This thing has been around too long. I don't have a use for it right now so I need it gone.

    The best price I can do is $500 shipped and I will even throw in a BBR pegmount. And that is one hell of a steal.

    I'm even up for a trade if you have something interesting. I am looking for a stocker for stunting or maybe a rolling chassis. Also, if you have a honda bottom end I would be interested.



    ALSO FOR SALE:



    -completely stock xtreme engine all black with the close ratio tranny and crf50 stud pattern. Runs great, lots of compression, comes with all electrical. carb, uni air filter, etc.



    *checking condition of crases for a small crack on the xtreme, not sure yet*



    $350 shipped.

    No false neutrals in any of the motors. They run great, pull hard, and are great motors to have.

    The one on the work bench is a stock bottom end it has been rebuilt once on the bottom end. The other is the motor in my bike but i forgot that i bored the cases to 54mm so that wouldn't do you any good.
