Motorcycle Dies At High Rpm

Its happened 3 times so far.

Motorcycle dies at high rpm. Sometimes I have to gas it when idling to keep it running. I dont think you have enough fuel pressure at high RPM wide open throttle and it makes it run lean at those RPMs. If the bike begins to sputter or dies completely its sucking in that spray and you know the gaskets are going bad.

Typically a lean condition caused by an air leak between the butterfly and the head or a. Hey bro it might be your kickstand sensor. The best idle speed really depends on the type of engine and air to fuel ratio.

My best guess based on past experience would be fuel starvation. It has no problem at higher engine speeds. The cut out will last a split second as if it misfired and the bike feels kind of weak.

Fuel delivery problems usually result in power fading out but can cause a kind of misfire. Its died while idling several times. Enough fuel is getting to the carburetor in most circumstances to keep it running but when pushed to near its maximum power for a while the float bowl is getting drained.

If your engine idle is set correctly at 1000 rpm on tick over and your not using after market exhausts then your problem is properbly air filter. I have about 6000 miles on it. Could be my mind playing tricks on me by saying I think the bike feels weak.

A motorcycle shouldnt be at constant high RPMs because that will wear out the engine a lot faster as well as rattle your ears and everyone elses around you. If you have unmetered air getting into your system between the butterfly of the carburetor and the cylinder head this will create a lean condition. I changed the spark plugs and ran some sea-foam through it and still continuing to cut out.
