got a Jawa moped.
on taking apart the engine i noticed an odd port arrangement
in the cylinder.
instead of the transfers just being holes in the cylinder these
transfers were a diagonal slash going up the cylinder wall
kinda reminds me of Puch open transfers....
my engine is the 207 but i also have access to a 210 and
have noticed the same port arrangement in that motor to.
anybody have any knowledge about these ?
trevor , i know you have them.
