SUPG0205   SuperTigre   G-75 Ring w/Muffler 
TECH NOTES
   Super Tigre'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-75K's bolted onto the crankcase).

FEATURES: Ringed piston
          Dual ball bearing-supported crankshaft
          Unique bolt through muffler that uses muffler bolts, lock washers,
            and nuts to hold the muffler to the engine (no more stripped
            threads on the crankcase or muffler).
          Schnuerle scavenged
          Two-Year Warranty

INCLUDES: One Assembled G75 Engine w/Glow Plug
          One Muffler
          One Exhaust Stack w/Gasket, Pressure Fitting, and Mounting Hardware
          One Carburetor
          One Set of Instructions, Parts Diagram, and SuperTigre decals
SPECS:    Bore:         1.024" (26mm)
          Displacement: .75 cubic inches (12.21cc)
          Output:       2.18 bhp at 15,600 rpm
          RPM Range:  2,500-16,000
          Stroke:       .906" (23mm)
          Weight w/o muffler: 588g (20.63oz)
          Weight with muffler: 766g (27.0oz)
          Width between centers of mounting holes: 50mm (1.97")
          Length between centers of mounting holes: 20mm (.79")
          Width of crankcase excluding mounting flanges: 42mm (1.65")
          Length from backplate to front of drive washer: 97mm (3.82")
          Height from bottom of crankcase to top of head: 105mm 4.13")
          Crankshaft size: 5/16"-24
          Suggested prop size: 12x6, 13x6

          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.
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.
