Motorcycle Questions? Ask a Mechanic.
Hi and thank you for your question.
I do have a question for you. What are you calling blow by? When a technician hears the term blow by, immediately he thinks of the combustion gases passing by the rings and entering the crank case, as evidenced by a blackening of the piston below the rings. I suspect you have not removed your pistons to investigate this problem so what do you mean by blow by?
What exactly did you mean by blow by?
