I read up about the problems with the one-way, as soon as my wheeler made that all familiar sound ..the first time..(the starter turning over freely with out any engagement, followed by a chatter, then the motor would turn over), I wasted no time fixing it. I didn't even fire it up after that. The crazy thing about it..is it was as chewed up as the picture maddog has (a few posts up). Couldn't imagine how bad it could get if you're hear'n it everytime you start the bike...Makes me cringe...
The starter clutch continues to spin over the 52 tooth even after its started. So its being damaged as your motor continues to run, not just when your starting it.
Some engineer(s) from yamaha should have had his/her/their @ss kicked for that $hitty design, let alone 1 year, but the continuence of it for the following years.
Felt good to vent!
