Vapor lock

[Mwilson87]

Anybody had any problems with what seems to be the engine trying to vapor lock after cutting it off while it is hot and trying to restart?

Vapor lock is when hot fuel vaporizes causing stalling or loss of fuel supply to the carb/engine. I think what you are talking about is carb boiling fuel into the engine. That can cause a slow bucking start if enough fuel gets into the engine. If this is what you have then yes some have experienced it and there are a couple cures.

Insulate your fuel lines from the rising heat.

Easy way to get around this.... As you start the bike crank the throttle wide open fast Right before you start it and let go of throttle as soon as it roars to life. Will start instantly and not sit there and crank and crank and crank...
