    P.S.

    Hi James,
    i have an 09 Aprilia RS125 coming over from the East coast mid February I bought it at Auction & it's a NSW stat write-off with very little wrong with it. The engine is available for sale if you were seeking a spare motor?
    Cheers, Marty

    P.S. When doing the compression test did you have the throttle fully open? If not that could also produce a low result!

    I don't want to trouble said friend again because it took a year to fix it the last time. It won't start, but when you try and start it, it sounds really dry?? only way i can think of describing it.

    I'm chasing a mobile mechanic if anyone knows of someone please? Really want to get back on the road as I have not been able to ride in a loooooooooooong time.

    Thanks all

    James
    throttle position will give a slight reading but not 100psi difference

    my advice buy the spare engine will be cheaper and back on the road sooner

    Last time the bike back fired, something went bang and it wouldn't start again. The piston barely moved, it was kinda stuck in position. Trying to get the guy who fixed it last time to answer that question though.

    Any modifications? Exhaust, carb?

    Sounds like it's lean, or there's an air leak. If the carb wasn't looked at during the rebuild then that would explain why it happened again.

    ill bet lean soft seize < unsure of spelling haha.
    due to small jetting.

    new top end and piston may be all thats needed. hopefully.

    No nothing yet, haven't been able to do anything myself due to work and can not get hold of the guy that did the rebuild last time.
