I think I know the answer to this, but just in case I’m going to ask anyway.
I took the exhaust off, one side, so I could refit the centre stand. I thought it might be difficult to remove but the nuts came undone very easily. There is no copper gasket/ oring fitted. The exhaust fitted is an aftermarket 2 - 1. I’m not sure of the make.
So my question is should I fit copper gaskets when I refit the exhaust?
