    Help!!! wont start...

    Post by Skippy on Wed May 23, 2012 10:32 pm

    Got my bike out this evenin to prep ready for friday, bloody thing wont start!!!
    So far,
    Checked spark...got spark..
    Changed plug to be safe...new plug, no joy...
    Checked fuel....fuel going to carb...
    drained carb from bottom drain plug...no joy..
    Took reed block off, reeds fine...no joy
    tried bumping..no joy...
    tried towing with a van...no joy...engine just turns and sounds dead???
    took exhaust off to do reed block, had clean water in expansion chamber !!! drained water ....no joy!!!
    If somehow water has gone though the exhaust while washing and into the engine (hydrolocking) would I have felt it different through / when kicking it ???

    Desperado, only got tomorrow night to sort or I'm staying home Friday

    You,d know if it had hydro locked skip my trials bike did it and i thought it was fucked engine went really tite trying to kit it.

    Try a different spark plug some plugs wont fire under compression, and you can have a new plug and still be a dud.
    Poor a little bit of petrol down the plug hole and give it a boot see what happens.

    Failing all that box of swan.

    I know it's a long shot, and I'm not taking the piss here, but you haven't left the exhaust bung in the end of the pipe??

    Don't think so, not a 100% sure though. I know that a CDI from a 2006 YZ won't work on my bike, 2005 YZ. Pretty sure they are year and model specific.
    Bonkeye on here has 300 gasser, might be worth a pm.
