Pit Bike Set-Up Info
TBolt USA Tech Database!


Pre-ride preparation and inspection:

These are procedures that are recomended for all motorcycles and pitbikes.


  1. Change the oil right away before you start the engine with 10w40 non-synthetic oil. The oil that comes in the engine is ONLY to be used if someone accidentally turns the engine over. This is LOW-QUALITY oil that should not be run. 900ml oil MAX

  2. Engine Break in: Run at low speeds with very low loads for the first 2-4 hrs. It is ok to rev it up, just dont put a large load on the engine: Ex. big hills ect.

  3. Check all fasteners, Locktite is a liquid that holds bolts secure and is available at most any auto parts stores. Loctite nuts and bolts with Blue loctite. If bolts fall off riding and cause damage or loss its not covered under warrenty

  4. Use RED locktite for the chassis , shock and subframe bolts, rear sprocket bolts
