Aprilia Tuareg wind 125 with a rotax 123 engine timing?
Hi I have an Aprilia Tuareg 125 with a rotax 123 engine,should the ignition timing be set to 1.84mm BTDC?,mine is set at 1.35 mm and i am not happy with the performance and I noticed power loss between 5000 and 6000 revs.the spring that holds the power valve seems to be very tall when i take the cover off and I was thinking that probably sombody pulled it,do you know how long this should be.Thks
