MPG from a malossi 210 engine?
I have 210 with long stroke crank 30 mil delorto and reed valve. Does about 80 on a full tank but don't run it too low as it runs lean so usually about 70. Seems it is slightly better since I put an augusto on it. Into a wind will hammer it harder but pull back the throttle ...and watch that needle dive. You will have a lifetime of carrying a petrol can so get a good backrest.
