My 6R has one of those carbon look huggers/chain guards fitted. I have not had the bike very long, but recently I noticed a small amount of damage to the end can. It is on the inside, near to where the rear brake hose fits onto the swingarm, so it is not easily seen. This appears to have been caused by the bolt head on the bracket which attaches the hugger to the swingarm. The bolt head has hit the exhaust when the suspension is under load and has put a hole in the outer skin and pierced through the inner layers. I have put my hand over the damaged area when the engine is running and I can feel exhaust gasses leaking from it. I can modify the bracket and fixing easily. What can I use to make a good repair to the exhaust?
