[lms1977]

How high does it rev ?? If it just revs to wot then look at your carb sllides the needles or a needle might be stuck and didnt go into the carb properly holding the slide up or the slide groove might not be lined up in the carb

[Zbb]

Ok I'll look into that

[1CrazyBastard]

Pull air filter and look into the carb throats do you see both slides all the way down ? if not check needle is in center of carb properly when you installed carb top and the grove in the slide is lined up with the pin in the carb so it can go in properly

[Zbb]

A slide was stuck I got it up and going and there's no power on the top end

What is your elevation?

[y2ks]

Does it run fine till wot what mods do you have is it just pipes

[Zbb]

No more than 3000 ft yea jus the pipes

[y2ks]

Sound like you to rich! Being to rich on the top end will sometimes cause your engine to rap out and not make any power and make the engine overheat. If it only happens at the wot its in your main jets im at 1100 and have almost the same mods and i run a 180 main and im dialed in you are much higher at 3000 with less air hope this helps.
