Have to split the case to replace 2nd gear on 650R...

Recommended Posts

So I'm dreading splitting the case to replace 2nd gear. Is there anything else I should think about doing while I'm in there? Has anyone else had any trouble with the 650's tranny?

Never heard much on 650R tranny problems.. While your at it at least get a new piston kit & cam chain.

Theres probably no need, these XR650R's are bloody tough :smirk:

The NiCom bores last forever but the piston and rings wear out.:rant:

My 01 is still going ,,with stock piston and rings.

Hence my point :smirk:

Measure the ring end gap, measure the piston. If still in specs run them again. I would replace the rings if not near minimum spec.

That's what I intend to do. I expect the piston and rings to be fine as the bike has run great since it was bought in 01'. Wow it's hard to believe it's 10 years old already.:smirk:

The decades just slip by it seems.

I had to go back into my XL at 8500 miles for a gasket leak and found the ring end gap near exactly what I set them at. Put it back together with new gaskets only and it runs great.

Cant' fix it if it aint broke

My 2000 BRP is 11 years old and done 8350km throughout its life, 760kms a year.

Amazing bike, especially for its age.
