Average engine kit assembly time may take two to four hours, perhaps longer or even a few days, depending on mechanical ability. But the joy of assembling your engine and kit components to your bike, will give you complete satisfaction when you fire that StarFire motor into life for the first time, to motorize your push bike. A rewarding joy and challenge is found, in designing the custom installation of your own.

The StarFire brand of bike motor kit is sold to a global market, with a large volume of sales to North American, therefore, US compliance requires StarFire engine and kit components to be produced to a high standard of engineering quality.
Using only Top Quality components in the StarFire bicycle engine kits, such as Japanese Needle Roller Bearings - Larger 203 Big End Bearings - Gt2 Engine Cylinder, has a chromed barrel for better Engine Performance and Endurance - Ball Bearing Chain Idler - Heavy Duty 415 Drive Chain - New Push Button Clutch Lever - Accelerator Kill Switch for safety - New Free Breathing Cylinder with Big Ports.
StarFire engines are economical to run and will travel approximately 100 K's on one dollar of two stroke petrol mix.

It is strongly recommended that a run in period at low speeds of 15/20 kph on short 20/30 minute journeys to prevent engine over heating, be observed. When your StarFire Engine has been run in, this will give longevity of engine life, better engine performance and extra power with a lower fuel consumption.
During the run in period, we recommend, that the petrol to oil mix for your two stroke engine be...18 parts fuel to 1 part of top quality two stroke motor oil. After your engine has been run in, burning approx 15 litres at fuel ratio 18:1 through the engine motor, you can change the petrol to oil mixture to...25 parts fuel to 1 part of quality synthetic two stroke motor oil, such as Castrol R30 or the top quality Castrol A747 or Shell Advance. Along with cleaner motor running, synthetic two stroke racing oils give a more fragrant exhaust emissions with less smoke than regular two stroke fuel oil.


The ‘RUN IN’  fuel ratio mix for your new StarFire engine motor - 18:1 - Burning approx 15 Litres at the 18:1 ratio through the engine.
For a five litre fuel storage container, divide 5000 by 18 = 277ml - this is the component synthetic two stroke oil required to add to the empty 5 litre container before adding the unleaded petrol to make up the recommended fuel mix for your StarFire two stroke engine motor.
For a two litre fuel storage container, divide 2000 by 18 = 111ml - this the component quantity of synthetic two stroke oil required to be added to the empty 2 litre container before adding the unleaded petrol to make up the recommended fuel mix for your StarFire two stroke engine motor.
Adopt the same proceedure after burning approx 15 litres of fuel at 18:1 when your GEN III engine motor is run in, using the fuel ratio of 25:1

The decision to motorize your bike is worth considering in points of kit quality and engine make up. Even though two stroke bike engine motors appear similar on the out side, others assemble with the cheaper standard, short life friction bushings.
StarFire engines are a top quality assembled unit and incorporate the larger 6203 P5 crankshaft bearings with Dual Japanese needle bearings on the connecting rod, with chromed cylinder for a better performance and extended life.

Some engine kit resellers that offer higher or lower priced engine kits do not guarantee the product they sell, therefore in the event of breakdown, a kit purchased from the reseller will in effect cost twice as much, when a replacement for the dud is required.
