Has anyone blanked off the hole rear right in the air box and fitted a filter to the rear cylinder cover or the black rubber pipe? I only ask as No.3 intake stack is starting to get that sticky oily build up. Cheers Mark
Are you getting excessive oil accumulating in the air box? Maybe your rings are getting worn and allowing too much blow by? Usually the culprit
At 20k I would hope not...as I said, it's just the start of the normal build up over time as you would expect. It's all sparkly clean other than that. I got rid of the PAIR but now the breather needs deleting....maybe I'll do it then post results
