Inspect the throttle cable that it s routed properly and doesn t get pinched by the handlebars turning motion and not intertwined with the brake or clutch cables and electric start cable if applicable.
Dirt bike throttle cable sticking.
Additionally the throttle cable just through general wear and tear stretches breaks or thanks to the dirt build up gets sticky too.
A stretched throttle cable won t give your bike much life and obviously a broken cable doesn t work but a sticky cable or throttle tube can produce these kinds of results.
A sticky throttle could be caused by worn cables lack of lubrication in the cables or the cable getting bound up somewhere in the mechanism.
A few weeks ago i dropped my bike in a creek and sucked in quite a bit of water.
Drained it out and bike was good to go.
The cables can bind under the tank or in the handgrip.
If the screws in the throttle housing are too tight it could cause the cable to stick.
But within 2 7 seconds ish of riding it i could tell that the throttle needed some attention.
Pretty darn cool bike actually.
Although it would eventually.
It had a definite and annoying stick at the start.
Not only was the dirt bike throttle sticking it was not snapping back and it seemed like the throttle wouldn t return.
Or it can be caused by an issue with the carburetor or efi.
Little else terrifies a rider on a dirt bike when that pin gets stuck.
Bike is a ktm 2 stroke.
