Modern Vespa

Well I didn't get the muffler seated properly and now it is making more noise
than prior.

I would like to ride first thing in the am. Can it be ridden without causing damage or should it be re fitted first.

(Crazy 24mm drain bolt on the Lx 150)

I wouldn't ride it without fixing it. A leak right at the exhaust port can burn a valve.

id put it on right ,you could break a stud bouncing around.(bus)

Thanks for the advise, I was thinking I could burn a valve.....

I don't know about the LX, but on the GT there was concern about burning the brake lining when the exhaust gasket begins to leak.
