Well I was having some electral problems last week, it would lose spark randomly and break up alittle up top when it ran, and finally after i thought i had it fixed it died on me. I suspected the stator so i took the cover off and a small dismembered screw fell out. Hmm thats probably related to my problem. Then i noticed the nubs on the flywheel were F'd up. Then i saw the magnetic pickup thing held on one screw and all cockeyed (hehe funny word) I took the pickup off and it was trashed. lots of the plastic was gone as was the magnet, it must of gotten punted at over 10k rpm, cuz i was hauling. No wonder it was breaking up at top, i was probably getting timing curves a dyna fs could only dream of! So, I need a new pickup. I also am wondering if the flywheel is junk now that the nubs have been damaged. Ill get a pic up soon so the damage can be assesed. If any one has a pickup let me know. The stator and a bunch of wires are all connected so i fear yamaha selld them as a unit for extreem cost
