    Bike turns on but needs to be kept rev or it will shut down

    I just started riding my newly put together CX500 Cafe Racer so I have no idea about mechanics or engines.

    This morning it was drizzling and I rode the bike fine I got to one place and spent 2hours. (normally i need to leave the shock fully for a bout a minute before it goes to iddle) Then I got in the bike and i had to rev the engine or the it will shot down. I though it was a matter of the bike not been warm enough so started riding but as I was slowing down for a stop or something the bike would turn off even if the clutch was pressed.

    Since I thought it was a matter of the bike not being warm enough, I continued to ride like that, turning it back on after every stop. But realize it was not about how warm it was… I think it had to do with the flow of the gas since it would sound explosions and did not sounded right.

    Please help me understand whats going on, what can i do, and why did it happened.

    Thank you Friends!

    It sounds reasonably likely that you have got water in the plug wells. Pull the plug caps for a look. If you look at the sides of the heads there is a drilling to allow water to get back out if it gets in. This may be blocked.

    Spark plugs. Pull the wires that go into the ends of the cylinders. Pull the black thing straight out of the cylinder - don't pull out the small wire.

    Wasps like to use those holes as nests so they will often be filled with mud.
    You can use a drill bit (turn it with your fingers) to clear them and then either blow them out or use pipe cleaners to finish clearing them.

    we are all given sh*t in life, but some of us learn to turn it into fertilizer and grow from it, and some us try to fling it on others like monkeys.

    Hello all, I did try the spark plugs and the draining holes. One of them was clogged I clean them both well but there was no sing of humidity.

    BUT THE PROBLEM PERSIST! : (

    I applied a fuel additive and idle the bike for a while...

    Any other suggestions?

    Please help me get this baby running!
