Motorcycle Questions? Ask a Mechanic.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, proposed preliminary tries (if have not been done):
Please post back results / observations of the above once tried.
On similar type of engines, yes.
Or perhaps you would prefer a second opinion / alternate approach to your concern. The question would now be re-opened as I would rather opt out.
Good luck with the repairs.
