cc engineering Posted April 30, 2013 Share Posted April 30, 2013 Hi all, just wondering if anybody can help. Need to know how to empty the crank case of oil and grime, the bike has been stood some time and every time it tries to start the plug clogs up with gray/brown gunk from the crank.. Thanks in advance Link to comment Share on other sites More sharing options...
Moderator DirtyDT Posted April 30, 2013 Moderator Share Posted April 30, 2013 The plug and the crank oil are separate. There will be a sump plug under the gearbox. Undo this and the oil will drain. The plug colour should be more to do with the 2 stroke oild which is fed from a different oil tank attached to the frame. Link to comment Share on other sites More sharing options...
Moderator Cynic Posted April 30, 2013 Moderator Share Posted April 30, 2013 Oh.... This grey brown gunk. Not rusty oily water? You really need to pull the pot and see where the 'gunk' is coming from and confirm what it is. Have you checked the water and gearbox oil.
