Engine cutting out--AGAIN
Written by wkaufmann2000 on 7/27/2010 at 05:39 pm

My bet is that it has something to do with the engine getting short of
fuel when being revved that high.
I think it needs more fuel than the fuel system (fuel
filter/pump/petcock/carb) is able to deliver when the throttle is opened
As soon as you close the throttle a bit the fuel systen catches up and
the engine recovers...
What exactly the culprit is, is due to further investigation....

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.
