Your motorcycle has to be "re-jetted" if its a carborated motor. If its electronic fuel injection, it would have to be reprogrammed and hooked up to a dyno machine. Some EFI motors can receive downloads from a computer--this is done by the service department at a dealership however (its not something you can do at home on your own).
You need to know what circut of the carb that needs re-jetting. Fuel injected engines can be reprogramed if you have the reprogramming information and or a laptop w/ the approiate fuel pack. W/ a good fuel pack you can advance/ retard you ignition system according to speed and rpm. There a lost you can do on your own once you understand what fuel pack can accomidate all around adjustments in one unit.
There is an increasing demand in other countries, however, make sure you do research about the country first. Some places, like Brazil, are not compatible with U.S. televisions.
Ther should be an access panel in the top of gas tank that is where the air filter is located .
usually that has something to do with the carburetor. rather the air to gas ratio is not even or it needs cleaned.
4OUNCES OF 2-STROKE MOTORCYCLE OIL/GAL. OF GAS
Control of the ratio gas fuel/air in the burner.
it is a four stroke engine. gas only. use four stroke motorcycle oil when you change oil in the crankcase. clean air filter also.
The air filter is under the gas tank
Just simple compressed air, available for free at any gas station.
Keep it tuned, add an aftermarket air filter such as K&N, change the rear diff gear ratio,
If by "air" you mean oxygen, then the mole ratio can by found by balancing a reaction equation. CH4 + 202 -> CO2 + 2H2O The ratio is 1:2.
Typically Natural gas req 10:1 air to gas ratio. therefore 150,000 btuh= 150 cfh so air required would be 1500 cfh air.
A lean mixture is referring to the gas/air ratio. Lean being less gas
Typically Nitrogen in factory produced shocks, Or compressed air in motorcycle adjustable air shocks.
