RE: WOW!! New DL 111cc and 55cc !
No Problem, The 50 and 55 are essentialy the same engine. Only difference is a 2mm larger bore. So that means new piston, ring, and cylinder. crankcase is the same except it's machined to accept the larger cylinder stub and they are now serial numbered at the factory. It's just as user friendly and powerful as it's predecessor. Could have a miniscule power advantage but I'll need more time determine that with any certainty.
