Tech Tips
Use any high quality 93 Octane Pump Gas.
- Use high quality synthetic two-stroke oil mixed at 80:1 (1.6 ounces of oil per gallon of gas) we use and recommend Maxima Formula K2.
- Use high quality motorcycle transmission oil, we use and recommend Maxima MTL 2-Cycle Transmission Lube 75wt
The bike comes from the factory with an NGK – BP5ES; we have found that this plug works great. The gap should be set at .020 (.50mm).
The air filter needs to be kept clean; riding conditions will determine how often it is cleaned. Use high quality motorcycle foam air filter cleaning fluid to clean the filter and high quality motorcycle foam air filter oil on the filter. Follow the manufacturer’s instructions on how to clean and oil the filter. We use and recommend Maxima air filter cleaner and air filter oil. We suggest that you protect the air filter when you wash the bike.
-Never start the bike immediately after it has been washed, always check the air filter and the airbox prior to starting in order to make sure that water has not entered the filter/airbox.
The factory has equipped the carburetor with 30 & 33 pilot jets along with 124 & 126 main jets. For sea level in North America we suggest that you start with a 36 pilot and a 118 main jet. Altitude, temperature and humidity can have an effect on carburetion. Check with your local dealer for what works best in your area. The float level should be set at 18.5 mm, the gas screw should be set at around 4 turns out, this will have to be adjusted for the individual operating conditions. (Turning the screw out, counterclockwise richens the idle/slow speed mixture).
The front and rear spokes should be checked initially and after the first hour of operation. Adjust as required; they need to be checked on a regular basis, especially during the break-in period.
-If you have any questions about any of these items please contact your local dealer here. You can also contact Sherco USA via our contact page or at 800-607-8742.
