Okay I have checked the adjustment of the oil pump and cable and noticed that its way off (set to use too much). I have slackened it off all I can but there is no more play - it is slightly better but still way off. I suspect that my cable may be too short - does this sound likely?

Also even as I have it now, I turn the throttle and only after a certain amount of turn, does the pump start to open (due to slackness of the cable). This will only get more the closer I adjust the cable to correct position. Does this sound right? Only after quarter (or even more) throttle, does the oil pump start to open? Before adjustment, the pump opened as soon as the throttle was moved (no slack in the cable).

Thanks guys.
