The original poster is asking about an MDS 2.18 in a Big Bingo. Doesn't sound like a "student" to me.
Anyways, back on the subject at hand: the 2.18 supposedly is the first of the latest series of redesigned MDSs. Does anybody know if this engine can take low oil fuel like the big Super Tigres?
Also, how much is a Pitts muffler for it?
