G75 RING W/ MUFFLER

SuperTigre's new G-75 is an updated version of the S75-K. The main
differences between the two engines are that the G-75 is a one-piece crankcase
(the S75-K was a two-piece) and the G-75's muffler is a bolt-through-the-crank-
case (where the S-75Ks bolted onto the crankcase).

COMMENTS: Since this engine uses the exhaust stack from the S-75K, some after- market mufflers will fit this engine (using the muffler screws from the G75) and some will not. Check the optionals in the Accessory Completion Guide for after-market exhaust systems that will work.
