I have 4000 miles on my 03 450f and not had any mechanical problems until today. Today the starter worked a couple times, then wouldnt engage. So is there a trick set up to replace this clutch? Is it a Yamaha only item or a bearing that can be had at a bearing shop? The starter spins just fine. I have abused the Heck out of this starter, until today I had used the kick start a total of 7 times. Hope you guys can help me out.
