shane_vor, I am used to him and his antics, he is being lulled into a false sense of security,
TB, I have put 3 tanks through it in the last four days and I would say just about all of the time was spent on the limiter(there are few shaking their heads around here at the moment, I would just pull the clutch in to stop the drive , change direction and dump it back into drive again, all the time not letting up on the throttle. That Ba ba ba ba of the limiter really puts poeple off, It was only the last 30 ks or so that it got a little ugly, the caring type that I am I made sure I beat the shit out of it on the way back
seriously, I suspect some blow by and pressurising of crankcase could be happening, will check crankcase vent,will make a felpro gasket for it tommorow and glue the bastard together, all good
