I am in the process of tuning, or rather trying to tune a Blaster.
Leak Test done, Compression test done.
I am at the Air adjustment screw currently but I can't seem to grasp the tuning method.
Problem is, on the one bike when I seem to get the highest idling speed set with adjusting the screw, the transition from idle to 1/4 throttle seems really bad and weak. When I on the other hand, I adjust the screw till the transition from idle to 1/4 throttle seems best, I end up 2 turns (anti-clocks) to where the idle was highest (1.7 turns out from closed).
Which is right?
Then on a different bike I cant seem to distinguish between idle going up or down when I do adjust. Will the tuning be easier when a tacho of some sorts is used?
Any advice would be appreciated. I really want to complete this idle adjust step so I can go onto plug chopping.
