I just finished putting on a new muffler on my pa50II...3 km's down the road, I hear a 'pop'...5 seconds later the characteristic shimmy of a flat tire...and I'm off the road.
Could there be any correlation between the new muffler and the tire pop?
Or was the tube just getting worn? It sounds like a really big hole though...tubes shouldn't just randomly pop like that...
Anyways, that's my rant... now off to 2 hours of tire changing...
