cutout/stumble on an MC engine

[Jorgen Karlsson]

Hi,

My car did that when I first installed the free flowing air filter. The
boost climbed high enough for the ecu to cut the fuel pump. I guess that it
is not very likely for this to happen on a MC, the boost limit is the same
but the stock boost is a lot lower.
