I'm pretty mechanical and I fully realize that the newer bikes today are more tweaked for competitive performance, but I would think tranny gears should last for years.
I have 15/42 gearing because I don't like over reving and a lot of So Cal and baja is high speed. But nothing out of the ordinary. I ride with guys that have EXC's, CRF's, XR's and WR's. I always keep my chain adjusted properly, because my old 99 610 was very sensitive to chain tension.
I really haven't heard too much about Husky's having weak tranny's so I'm thinking either all my gears were bad from the factory or the cases weren't machined properly so the gears weren't meshing exactly right... Or the interal gear lubrication isn't working properly.
I do get on the pavement, but just to get to the next trail. When I'm on the pavement I'm easy on the clutch and throttle mainly to save my knobbies which inturn is easy on everything else.
Someone made a comment that 4k+ miles was a lot for a TE, but I don't understand that???? I have over 80k miles on my 94 Elefant and over 20k miles on my 99 610 TE with no issues. When the day comes that an enduro type bike can't make it to 10k+ miles without and major overhaul somethings wrong.
They are racing EXC's in the Dakar Ralley with zero tranny issues.
I've been a Husky fanatic for years, but I can't accept poor reliability, and not to mention these tranny failures aren't cheap. I hope Cagive North America helps me out with this, but we'll see.
