I dunno about you all but I have never heard about peoples front sprockets coming off. Well when it came off it cause alot of Damage, the Plate Cover is mangled and the bolt striped and the shaft is stripped. The Mechanic that rear geared my bike for the front and the back was TK Motors. When we took the cover off the sprocket pretty much just fell out, there was no Lock bolt. I took it to TK and showed them what happened; he said Yamahas have a tendency to stripped the bolts. Well Miami Mike called 3 Mechanics that he knows one from Coyote, Sunwest and one other, They ALL said that is not true. If a sprocket is put on properly it WILL NOT come off. TK refused to make it right, they wanted to charge me. Miami even tried telling him that this was not wear and tear that the sprocket was not installed right, still TK said if it was put on wrong it would have come off before 2 months. Which is the time frame I had it re-geared. I took my bike to Coyote and they told me the there is no indication a lock bolt was there and a sprocket does not come off if put on correctly it should stay on for years unless removed by someone….. The damage that it did to my bike I am looking at a minimum of 1000.00 to fix it… TK Motors did NOT stand by their work!!!! They did NOT make things right!!!! Miami was more upset than I was and made it know to never do business with them again and that he will not refer anyone to them. Miami loaded my bike back on the truck and we left. And letting you know another person after I told them about TK, their bike has been making sounds and they had there bike re-geared there as well. So he will be looking at his bike. Just wanted you to know that it was a Mechanic that proved they will not stand by their work.

Couple of things....
Bart looked at the bike yesterday and was giving you rough ideas as to what the problems were with trying to repair it. He did not work on your bike that original day as I personally did all the work so his being non-committal on the solutions are understandable. We did not have a chance to really discuss any solutions since you guys decided to take the bike away.
When I worked on your bike we did everything we could to keep the cost down including using your parts for you. When I removed the front sprocket nut the threads were already damaged and I replaced the nut (with the lock washer) using a nut off a blown motor of Glen Consers.
In hindsight maybe I should have mentioned this at the time but due to the fact that Yamaha uses a very fine thread and very few of them it just seemed that the old nut had worn out the threads on the nut. The threads appeard fine on the output shaft.
I am human and can and do make mistakes from time to time. I also own and race Yamahas so I know how the countershaft works. The bike went out of here with the nut and lockwasher properly installed.
That being said, we are definately willing to help with the situation. While I will not replace the motor for free we can try to drill and tap the output shaft for a bolt similar to the honda's setup. This I will do at no charge. Please feel free to contact me to discuss it further.
I also understand why some dealers have not ever seen problems with these nuts. How many of you actually use a dealer to change sprockets?
We do stand behind our work and will do so in this case up to what we did. We will even help with situations beyond our control.
I am open to all the flaming you want fire away!
