Finding oil leaks
Hi,
To find an oil leak first wash down the motor with GUNK or similar degreaser,then dry it off or leave to dry.
Then dust the motor all over (or in the suspect area) with Talcum powder,run the bike up or take it for a short run (in the dry) .Then inspect it again, then all should become clear.This works for seals,gasket faces and porous castings.A bit time consumeing but very cheap!
