Yes, I drove it until it stopped. Guess mine has enough mud in there to stop it. LOL Just kidding. How many miles you have on the machine? At 200 it should be quiet. It's just the springs or ball socket between exhaust header and muffler moving back and forth. Think when enough soot gets between the metal joint it quiets down.
Yeah this squeaking is driving me nuts too. I narrowed it down to the gasket between the exhaust header and muffler pipe. Tried adding some heat resistance silicone oil on it but hard angle to get in there effectively. Stopped the squeaking for a few minutes. So I'll have to take the exhaust apart and add it all around and see what happens.
I have at kind of a "rattly " sound coming from the back some were but only at certain RPMs. .at low cruising rpms.. The brakes were very squeaky. But it was just dust in the new brakes and rotors breaking in and I would hose them out after each ride and eventually it stoped.
