Reminder to help you in your settings:

The 2-stroke engine requires precision in your drive settings, remember that the drive replaces the gearbox. If your engine gives as an example 13hp at 12,500 rpm, it will give less power at 11,000 rpm and less power at 13,500 in overspeed. That's why it is important to find the perfect weight that will exploit the right speed throughout the opening of the drive. It is necessary that this rise is longitudinal and without burr. A pebble too light will send you over-revving and will not allow your drive to close properly, on the contrary, a too heavy roller will close too quickly the drive, and you will not manage to reach the power regime.

Choose your weight before ordering.
