I'm running 14-51 on my 2010 450F and the chain is rubbing against the rear guard pretty heavily. Does anybody have any ideas how to fix this other than gearing changes? Does anybody make an adjustable one so I can "lower" it to work with the 51-tooth sprocket? I called TM Designworks and it sounds like I'd have the same problem with their stuff too.

Thanks in advance,
David

You could always go with a 13-48 gearing

That's stock gearing. I don't know why someone would bother to change it to 14/51 unless they wanted the ability to gear it down by changing front sprockets.

The only solutions for the rubbing problem all involve some degree of fabrication.

That's it but also in my experience the 14-tooth countershaft sprockets seem to last longer (than 13's).

They do, but I think you'd find that the 13 lasts as long as a good high quality rear chain does, anyway. I know mine did.
