Default Re: what did you do to your motor bike today?

Eventually, you may lose power altogether. I'm just telling you the fact is that ported 2 strokes need back pressure to maintain proper timing.

they dont need back pressure for proper timing, timing is controlled by the ports in the jug and do no change unless you do port work. piston ported two strokes need back pressure to keep the motor from over scavenging the fuel charge from the cylinder.
