    Use a hair dryer to warm it up,if it starts to misfire,it's toast

    I have heard of the rev limiter causing problems. But it has always been fine and I have not changed any of the little dials.It really only does it at highway speed and when I wined out a gear getting on it.It will go 50%. LOse i think the rear cylinder.But then It will clear up if I drive cool.Still missing at lo rpm until it clears up.
