Motorcycle Questions? Ask a Mechanic.
Hi and thank you for the question.
I suggest a little investigative diagnostics first. Let's pull the sparks plugs out and see what they look like.
I would also like to know if any repairs or service work has been done to the cycle recently. Or has it been sitting un-used for awhile? Please share any details no matter how insignias unrelated they seem to be, it may help speed up the repair process.
