Motorsport 250 gearbox options

[Colin Jay]

Back in the late 70's I raced a 305 kitted XL250K3, mainly in desert race type events and also did a lot of hard trail riding on it and never had any gearbox problems. As long as the gears are in good condition, not half knackered fron 30 years of abuse then I think you should be fairly right.

Sorry,

"Kush Sprockets are Australian Engineer designed and tested."

Yes they are made in China.  They still look like a good product with some AU design/engineer work!

Still want to see the sprocket part made from 7075 T-6 alloy.

You must have a melt down sighting some expansion chambers, black rims, blinged out chrome everything, and some shocks  .

You got it in one. Chambers should have a belly diameter limit as well - appropriate to the day and no upside down shocks. Never saw a black rim growing up either.

But I digress, not to say there isn't but haven't seen any XL gearbox troubles over time including McKenzie's monster hp engines with John Kemp aboard (Oz 4 stroke Champion), I think it's a non issue. I think the odds are proven to be on your side Mike.
