Last week i was riding my maxi for the second time and the head gasket blew out and caused me to soft seize. after fixing that every time i go out for i ride i get to nearly the same spot down the road (4 miles) and it loses all power, slows down to 5mph, not suddenly like a seize its more like its ran out of gas.
Also the burn pattern on the head is focused on the exhaust side,
is that normal? i thought you wanted an even burn pattern?
