New 2011 Super Hawk GT5-A Angle Fire 80/66cc Bicycle engine kit. We call this one the "Super Hawk" beacuse it is a regular GT5 bottom end with a Super Rat top end. Wide 40mm intake hith high compression head. With a 45 degree angle plug the new Super Hawk with a smaller profile to fit in frames to tight before. Head can be rotated 90 degrees if spark plug forward is desired.

Included is the new and improved design 80/66cc CNS V2 Racing Carburetor with a larger slide and chamber. Designed for the larger 80/66cc motors to deliver more air and fuel. Choke control lever mount to handle bars.

Grubee motors are considered by most the best engines on the market. From the superior craftsmanship to the extra parts included in the kit, you will know as soon as you open the box that you picked a winner.

All our motorized bicycle engine kits comes with everything but the gas and oil. Convert your men's 24" - 26" bicycle to a 20-40 MPH and 100-150 Miles per gallon machine. 2 Stroke Motors require oil mixed in with the gas. 16 to 1 (8oz per Gallon) when motor is new and 32 to 1 (4oz per Gallon) after break in period (about 1 or 2 tanks).

You can still pedal bike like normal with clutch lever held in or locked in with button. To start a 2 Stroke Bicycle Motor just hold in the clutch and pedal to get some speed then release the clutch to "Bump Start" the motor and off you go. To come to a stop once engine is running you can hold in clutch and engine will idle. Push Kill Switch on throttle to kill motor, clutch must be held in when bike is in motion or motor will keep running.

Engine kit will add about 24 lbs to your bike. Fits most standard V frame Men's 24" and bigger, we suggest 26". Engine kit is about 8.5" height 7" length 5" width. Kit fits on standard 25mm - 29mm frame tube. Larger frame size requires drilling into bike frame and use the universal motor mount..

China bike engine factories have always advertised their biggest engine as 80cc. However, the bore and stroke of an 80cc being 47x38mm only equals 66cc. Therefore there is no such thing as an 80cc bike motor and it truly does not exist. This is the biggest motor available.

Great Power - Fun Ride September 9, 2011
Reviewer: Steve Duncan from Springfield, MO United States  
This is a great little engine for almost any size frame and the installation is easy if you have limited mechanical experience. Take your time and do the install correctly otherwise you will need to redo what you missed.

Dont expect any of the assemblies to be be a direct fit or torquing enough to pull your front wheel off the ground.

Excellent for getting around in style with more cool factor then a moped. People will defenantely want to check out your ride. Have fun with it and always ride safe.
