    trouble starting my bike

    Post by Mills on Sat Jan 12, 2013 6:11 am

    i went out for a ride on my bike last week where it broke down and wouldnt start, i've had the exhaust today because last time im had the engine out it was full of fuel because the jets are too high.
    for some reason the bike starts up first time without the exhaust on but as soon as you give it any revs it dies. even with the elbow on the cylinder in dies
    can anyone help me with whats going on and how to fix it?

    Only thing I can think of about the exhaust thing, is its possibly blocked? Or restricting flow hmm. Take it off and tap it all over with a rubber mallet see if much crap falls out.

    Check air filter, it's that's full of shit it will be flooding and hard to start and fouling up plugs. Got a feeling it could be this, but still wouldn't explain about the exhaust. Clean it out with fuel or carb cleaner.

    Also if it is flooded, shut fuel off and take the plug out and kick its over 10-15 times and it should empty the cylinder of fuel. Easier than removing the exhaust.

    Okay thanks guys, I'm not sure the exhaust is blocked cause I managed to get some smoke out of it when I put the exhaust up against the bore when it was running but I'll give it a clean out anyway cause its still got crap in it by the looks of things
