Engine cutting out--AGAIN
Written by gibinmich on 7/27/2010 at 06:27 pm

I think Wolfgang hit the nail on the head. Its starving for gas, but because of
what? The fuel filter and petcock would be the easiest things to check first.
Just curious, how many miles on the bike?

again, twice. I was able to recover the engine by pulling in the clutch,
letting the engine slow down for 5-8 seconds then revving the engine three short
revs then letting the clutch out. It was almost like I cleared the carbs or
something. Still a mystery, hopefully tomorrow will clean K&N air filter and
check the carbs( I have no idea what to do to them) and maybe change the oil.
It almost seems like when under load something happens and I correct it by
pulling in the clutch, free wheel for seconds and then restart.
