My GPR can was getting louder or I thought it was anyway . Might be down to the fact im riding alot of KTM models instead of the blade but I thought it couldn't hurt to repack it anyway . It came apart ok usual drilled rivets and used a thin punch and rubber mallet to split can ends off. I cleaned ends up and repainted them with pj1 exhaust paint and left to dry . Today I repacked the can and assembled the can and refitted to the bike. It sounded quieter so job done.
I have dont want to wake my kids when I come back from an evening ride and if cans too loud old bill hear you from miles away. A happy medium is required I find .
