SuperTigre G-75 Dual BB Ringed w/Muffler (large view)
Notes from our tech department:
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 ***


Ringed piston
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).
Schnuerle scavenged

FUEL: 18% oil content MINIMUM. A synthetic/castor blend is highly
recommended. 10%-15% Nitromethane will work well. Higher levels of
of Nitromethane may require adjustment of the compression ratio to
prevent detonation.


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.
