spurdy Posted June 23, 2009 Report Share Posted June 23, 2009 Pickup coil wires are probably backwards. Check there to start since its the easiest place to begin. Either that or your timing is whacked out. Just saw this on my buddies bike last weekend, and the pickup coil wires were reversed. LOL it was pretty crazy! I have never seen a bike do this because the coil wires are switched. Coil wires can be placed on either plug, there is no right and left. Both plugs are fired at the same time while one piston is at TDC and the other is at BDC. That's why there are two ignition flags on the flywheel. I would say that it is likely his flywheel is loose and the timing is advance way too far. SP Quote Link to comment Share on other sites More sharing options...
