saw something sketchy on the gr650

[Scudder]

The 650 has been releasing exhaust from somewhere other than the exhaust pipe, and I'm having trouble getting the thing to quiet down. I've installed baffles in exhaust tips as mufflers.

So, I turn down the lights with one bright light to follow the smoke. As I looked at the exhaust pipe that leaves the engine I see a separation between the flange and the head. I notice bright color flames ( for lack of a better word) inside the head.

Of course it would seem I need exhaust gaskets, but is it normal to see bright sparks through the separation between the flange and the head? This gap might explain why the baffles I put in the pipes didn't really quiet anything down much.

Any suggestions?

Not normal, might be missing/damaged gasket or the some part of exhaust is not letting the flange fully seat into pocket.

While installing the exhaust did you have the cross pipe connected together?

I'm thinking that with it all tightened down, the cross pipe is pushing the exhaust apart enough to cause a gap near the head .

I would suggest taking the exhaust off and setting it in place loose. then tighten the cylinder bolts first until they are holding the pipe tight to the head and then tighten the cross-pipe and the rests of the exhaust.

I'm pretty sure you are correct. I connected the crossover and clamped it before bolting up the exhaust. Makes since that the exhaust didn't line up appropriately. I'll give it a shot tomorrow. Thanks a million.
