Due to having a PBI sprocket that was not machined right, I think my sprocket retainer groove on counter shaft may have been widen just a hair but it's so close to normal I think I am being over critical about possibly shiming (xr650lDave suggestion) the sprocket back JUST a hair.

Is there a bit of play in your shaft groove as to the CC sprocket having a bit of side to side movement with it tightened down?

In first pic is how it fits with new sprocket if it was bolted tight to new retainer, you can see it is perfectly flush with shaft splines and that is my main question, does yours fit the same way or does it sit back a hair like in picture two? Other ? is the side to side play, your's have some?

I;ve seen bad things with PBI sprockets. I will not use them. I think one led to
one of my friends stripped countershaft. I have used JT's, Sunstar's, Renthal's and the Rocky Mountain house brand Primary Drive. Oh, and other than the insane price there is nothing wrong with Honda ones.


FYI -- The sprocket is supposed to have a little bit of play. It is not held tight to the shaft or the retainer.

i thought once you put the retainer on and bolted it that stoped the sprocket from moving around on the shaft?

No, even a brand new shaft and sprocket is a loose fit

I little play is normal with the CS, but no "front to back" movement

i would rather go with a softer material like the OEM parts. they wear before the counter shaft.

The stock 15T has that extra black something on the outboard side. I bought a 14T Renthal, it does not have this. Seems to fit differently. Not wanting to create something out of nothing, I put the stock one right back on. Any thought?

As far as the hard rubber goes, consensus is its just for noise.

A new sprocket fill fit a skosh tighter than the used one because the splines on the sprocket don't have any wear on 'em.

Don't know any use history on Renthals, *should* be OK if it wasn't sold as extra-durable, or some such.

My set up has quite a bit of slop as well (much more than other bikes I've owned). Sounds like it's normal on a XR650L though. What is the stock gearing anyway? I have 14/48 and it's pretty buzzy for the street....I'm thinking of getting a 15t from Sprocket Specialists.
