We will update as soon as possible.
4 sets of weights (6,5-7-8-9g) for adjusting the variator. The weights are simply inserted into the sheath.
With this set you can tune your scooter perfectly. However, for continuous operation, we recommend finished coated weights.
Start tuning with the heaviest weights and gradually continue with an easier level until the engine runs uniformly at high rpm and reaches its maximum.
