Just a question

No problem! I've run into several bikes like this that needed attention for chain clearance, yet worked fine once this little trick was tried.
Good luck!
 
the chipped paint is the least of your problems, that is going to grind your chain down until it brakes and if your at full speed when that happens... well anyone here can tellyou that can end baddly. don't ride it anymore until you've fixed the problem
 
Maybe another fix would be to find someone with a tig welder. Just cut the section out were it rubs, turn it around so the bow is out and weld it back in. Cut it with a hack saw so the cut are thin,prolly have to take the rear tire out to do.............Curt
 
Hmm.. not sure about cutting and welding.. the risk of introducing weak points that could lead to a catastrophic failure goes up.

Yep a correctly done tig weld will make that the strongest area on that tube.......

Use a piece of round bar cold roll in the joint and you most likely have the strongest area on the entire bike, even a good mig weld or braze job would not scare me in that area.

Well I'm no expert by any means but I have seen a couple videos with this issue addressed and it was simply solved with a couple washers to act as shims between the hub and frame, seems simple enough (maybe to simple) but for the cost of 2 washers and 10 minutes work I would think it would be worth trying. Hope you find your answer and good luck.
 
Wow, if the smaller sprocket gets it close to clearing, this would get her done.

Cool thought Vonericson!

Just another thought. When I have had chain clearance problems, I use masking tape to make sure there is no further contact made. But that is if the same point of contact were to be made.
 
I'd remove the rear wheel, secure the dropouts, then spread the stays. If you have a couple ratchet straps and a sturdy door frame, you might not even have to remove the rear wheel.
