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).
*** 3-YEAR Warranty ***
Dual ball bearing-supported crankshaft
Unique bolt-through muffler uses muffler bolts, lock washers,
and nuts to hold muffler to engine (no more stripped threads on
the crankcase or muffler).

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.
