Starting the CSC TT250 or SG250 Motorcycle. Proper Fuel and Choke Operation.

The CSC SG250 and TT250 have manual fuel petcocks and carburetors. This article covers the specific procedure for starting these models.

Instructions for operating the fuel petcock and carburetor choke are included in the new motorcycle paperwork file that you received by mail when you ordered the new motorcycle.

The following instructions can also be found in the online Owner’s Manual on the CSC Motorcycles website.

In addition, please view the following helpful video for the SG250:

After you have unpacked your new motorcycle and completed the pre‐ride inspection, you are ready to start the motorcycle. Both the SG250 and TT250 share the same motor, equipped with an electric starter and kick starter. With either starter, the procedure is the same:

1. Turn the fuel petcock in the RUN position. (That is, with the lever positioned down, at the 6 o’clock position.)
2. With a cold engine and in cool weather, close the choke. On the SG250, this is accomplished by pushing the choke lever (left handlebar) all the way toward the rider. On the TT250, the choke handlebar lever is pushed all the way to the left.
3. Insert the ignition key and turn it to the ON position. Make sure the transmission is in the neutral position – look for the illuminated N light.

• Make sure the engine kill switch (right handlebar) is in the RUN position.
• If using the kick starter, vigorously kick the engine through a compression cycle, while opening the throttle slightly.
• If using the electric starter, depress the start button while opening the throttle slightly. Do not continue to crank the engine with the electric starter for more than a few seconds.
• As the engine starts, rock the throttle gently until the engine operates smoothly.
• Allow the engine to warm for at least one minute. As the engine warms, open the choke to the intermediate position – moving the choke lever halfway. After the engine has warmed, open the choke fully by moving the lever fully to the farthest position (that is, fully forward on the SG250 or fully to the right on the TT250.).

When you stop during a ride, it is not necessary to close the fuel petcock. Except in cold weather, it may not be necessary to close the choke to restart the engine. If the engine does not immediately start, move the choke lever to the half-choke position, then let the engine warm before fully opening the choke for riding.

When you are done riding for the day. It is recommended that you close the fuel petcock. Turn the lever to the closed (horizontal) position. The next time you prepare for a ride, repeat the procedure above, opening the fuel petcock and using the choke to start the cold engine.

The SG250 and TT250 are also equipped with a fuel reserve position on the petcock. As you are riding and the fuel level in the tank falls below approximately 2-inches, the engine will sputter as the flow of gas is interrupted. By turning the fuel petcock to the reserve position (lever to the 12 o-clock position) you open the fuel flow to the lower gas intake. At this point, you have approximately only 1-gallon of fuel remaining and need to refill as soon as possible.

Finally, for long-term storage, CSC recommends that you drain the fuel tank and/or treat the remaining fuel with stabilizer. Then start the motorcycle and let the engine warm up. After it is running smoothly, turn the fuel petcock to the closed position at 9 o’clock. This will shut off the flow of gas, causing the engine to die as soon as the remaining fuel is consumed from the carburetor.
