If you find that your boxed motorcycle is not going up in the towers, very often this is a problem with the carburettor :

• You may be too rich in fuel, not enough air is getting in. In this case, try switching to a smaller nozzle (we advise you to buy one multiple sprinkler kit, in order to be able to find the appropriate dimension).
• Your carburettor may not be adapted to the configuration of your machine (if you have changed exhaust par example). Try switching to a bigger carburetor (example: replace a 17.5 par a 19).

In all cases, we advise you to carry out a carburetor adjustment. This operation is quite complex, do not hesitate to contact a professional of two wheels!

If despite all the carburetion checks your motorcycle still does not go up in the towers, here are several points to check:

• ignition may be faulty, or improperly seated. Take it down and check its correct position.
• CDI may be restricted. (this is more often the case on recent models). Startridez-it or get yourself a new, more efficient model.
• There may be play in the crankshaft. Handling is complex, ask a professional or consult our tutorial to replace a crankshaft.
• The fuel filter may be dirty. Clean it or replace it.
• Candle et the antiparasite can sometimes malfunction. Check if there is spark in the candle (Unscrew the spark plug then let it touch a screw in the cylinder (be careful to hold it with pliers to avoid taking current). Kick (or press the starter) to see if it there is spark in the candle). If that doesn't work, replace your spark plug and suppressor.
