Sprocket change

Dave G · 28-Jul-2005, 20:29

If I'd thought about it at the time Iwould have stuck a 14 tooth front sprocket onthe S2R on its first service,but I didnt, and have now done just over a thousand miles.I know its not recommended to put a new sprocket on an old chain and vice versa,but how 'old' is old?
Do you think its worth changing now ? or should I wait another couple of thousand miles and change when I'll do the chain too,which'll be next year probably.
I know the difference the smaller front made to my 916,so its something I'm quite keen to do.

I changed front sprockets on a 20,000 mile old chain and nothing bad happened!

Changed mine at about 1500m, no trouble.

Just a question, how long do you expect your chain to last on the S2R? I'd expect 20-30,000 miles minumum. My current chain has 23,000 on it and it showing no signs of being near the end of its life. Having a scotoiler helps though.

Change it now. I changed mine at 2,000 miles.
It's also my experience that front sprockets wear out quicker than the chain and rear sprocket and I usually use 2 front sprockets for each chain and rear sprocket.

Might not be as much of a problem as I thought then.
20-30,000 miles from a chain is pretty good Rockhopper,I dont think I've quite managed that much yet. Hopefully the sprocket itself is held on the same way as all the other ones(I've not looked under the cover yet),in which case it should take about an hour or so to do.

Sixth gear here I come!!
