I think you have to buy the lever. It will happen again, though, so you would be wasting your money. Either remove it and clean the lever up, or I believe there was a post some while ago regarding rubbering it up yourself, if you see what I mean.
A search may find the post/thread, or someone may post up a link dreckly
Mine split (but was still hanging on) at the end too with barely any mileage on it, I used some super glue and its still there at 2000+miles. I assume the dipping method is similar to the stuff used for pliers or tool handles?
Mines ok after 2200 miles, but it really hurts my toe changing gear after a long rideout. Leavers looks like the end of a knife .
I may get some stiffer boots or try and find something at an auto jumble to go on it.
Mine came off pritty early took it totally off cleaned all the edges with Dick emery paper. nice and smooth feels better on the boot:clap: Nearly done 22k now and the Gearbox just seems to be getting better and smoother as time goes by.:clap:
