I have a brand new 2001 WR426, here is the deal.
This bike has 100miles on the 4th ride
On the 3rd ride: terrible clanking noise from left side of case. After removing the case, the flywheel & Stator, Stator magnets flew off destroying the inside of the flywheel as well as the stator.
Yamaha warranteed: new flywheel, new stator
These were installed correctly.
On 4th ride: Bike ran fine for first ride 20-30min. After cooling down,restarted ran fine for 10min. At idle again the terrible clanking noise. Again the stator & flywheel destroyed.At first I assumed the crank must be misaligned or installed incorrectly. But, there is no vibration, when the bike is running ok. Then we checked for play in the crank arm that attaches to the stator & flywheel. No play. The kick starter has no binds or kinks in the stroke.
I am at a total loss. I sold a XR400 that was plaqued with demons. I do not want to go through this again. I also own a YZF426 that is awesome! No problems:cool: :scream: :scream: :think Any help will be drastically appreciated by myself & MXTuner. Thanks
