Got my engine finally back into the frame again, only thing is i forgot to swap over the sump as the one on the bike has a small crack in it (no oil leaking but best to change it before hand!)

Does anyone know of a way of changing the sump whilst the engine is still in the frame?
I just cant seam to get anything on the rear centre bolt.

Surely it'll hit the collector box even if you get it un-done?

I have modded the collectorbox on mine by chopping the rear pipes and welding a collar on them with some simple jubille clamps.

Now the rear pipes stay attatched but the collectorbox just slides off allowing a quick whip off of the sump.

With a standard system the only way I know of is to remove the engine to get the exhaust off
