Hi. I'm new to these sites and not sure how these work but can anyone help me ive bought a lexmoto Arizona 125 and the engine went bang (oops) I bough a second hand engine which runs perfect but ive screwed the exhaust studs to tight and one has snapped so I'm putting my old head from my old engine on but I'm unsure how to set the timing.
Has anybody got a clue how to do it ...... thanks in advance.
