I did lose some on my MTX 3 in 2 years, but that was usually from the car catching air. If you think it is happening because of hard shifting, tighten the center screws in the 2 speed shoes. I run those with a reasonable amount of space between the shoes. This will smooth out the shifting. Other than that, without being there I could only speculate on what is causing the problem. Like I said, I have mine almost as long as anybody and haven't trashed one spur gear yet.
Me too..... I lost 1 spur gear only once during 1 year ownership. It was my fault not to mesh the 2nd gear correctly. You could open the 1st spur gear and see the gear mesh on the 2nd gear. If they are good, then re-install the 1st spur gear, clip it, and try to spin the gear before using it. If the gears can spin under their own rotational mass.... it's good and ready to go.
