My bike runs good at 20mph and starts within 10 feet. All is good till you hit 23mph then the motor acts like it wants to die like starving for air or out of gas. I put a new spark plug and wire in, cleaned the carb. cleaned the air filter, and put all new gaskets on the intake, carb, and exhaust and the problem is still there it wont go away. If you have any ideas please let me know.

Does it have a steady staccatto sound or does it cut out and then run O.K.?

The first one is too rich...move the needle clip up a notch. The second condition is from fuel starvation, and that can be caused by any number of things, including inadequate fuel flow, a float that is set too low or a gas cap that is not venting properly.
 
see my post:engine not 1oo percent. i stuck a oring between the carb and manifold and now the thing does not leak any air at all, i was having the same problew but i think this will fix it. read the post as there is more info there. frank
 
Thanks frank and Joe I have an o ring on the carb already. Mb monkey was helping me on the chat box and it was a fuel problem... my bike was to lean and the fuel filters were clogged.
runs a lot better know. Thanks for your help guys.

How do you set the float..... all my motor has is a u shaped brass piece held with a pin that has no adjustment. do you have to bend the u shaped brass thing.
 
I Had A Problem Like That, But Found My Carb Needed To Be Tweeked.then It Ran Fine. A Couple Of Times That Happened To Me Before That, But Stupid Me... I Had The Choke On...

I was wondering the same thing..., I cannot seem to find any pictures of the adjustment, before and after. I don't understand, and usually I do?!
