976376 part # is missing from both sides on my 2015 GRiSO...how could that happen??!!
I decided to check a bunch of bolts today, the exhaust manifold bolts were not tight, and even one of the studs spun out when trying to remove the nut instead of staying put. So...I decided to pull everything off...there are NO gaskets at all...surely this is a major assembly error at the factory, or are these assembled at the dealer typically?
Ordered a couple from MG Cycle this evening, should make I reckon quite a bit of difference in noise and performance not having this minor leak on both sides that I didn't even know had existed...at night with lights off using a flashlight I can see whisps of exhaust curling out right at the header, much more on the left side than the right side...now I think I've got the explanation for why the left pipe had purpled quite a bit and much more than the left side.
