Suzuki LTR450 Transmission Noise Cure?
 

Awesome four wheelers but that transmission noise was a deal breaker. Has anyone ever found out what it was that caused the whining?

Suzuki has revised the gear 2 times since the original change in '08. I have shelled the the original '08 (that took 15hrs) and the first updated '09 gears (they lasted not even 10hrs). I am now running the ATP Billet gears with no problems after 20hrs. Suzuki's 2nd (and latest) revision of the gears are wider. Though I haven't heard how well they are holding up yet.
