Hi, my son got a 2009 mikilon 250cc dirtbike in a trade a few days ago.
when ghe got it the bike wasent running at all, now i wonder what are the valve adjustements intervalls and clearance?
it backfires alot, will only run at high rews with choke. i have taking carb apart and cleaned it. I read on a swedish atv forum that the 250 cc water cooled engine suffored from a really bad carb adjustement out of the crate, not shure if that is true.Mikilon 250cc 09.jpg
