Hello all? new to this. Ive got a 2011 sherco 290 and it keeps cutting out on high rev as in just stops? I've been through the carb, pump, electrics, change plug running out of options?it runs fine on tickover starts fine but it kicks like a mule when it has stopped and try and restart it. its got a low compression head on so didn't think it would do this any help would be grateful thanks in advance
