My son's bike is smoking enough it's time to open it up.
Presumably it valve seals, rings or both. I'd have to bring the head to a machine shop to have them work on it. Should I just bring the whole engine? Or take the head off and remove the piston and measure the cylinder bore myself?
I've done quite a bit of work on larger engines and it's about as simple an engine as can be, but I'm wondering if the expense of any specialized tools would offset shop labor costs.
I live in Boston, work in Peabody or Manchester NH. Where should I take it?
