Set of 6 DOPPLER rollers Ø19X15,5mm grammage with the choices

Here is the set of 6 DOPPLER rollers, very good, they have an excellent finish. Reminder to help you in your settings:

The 2-stroke engine requires precision in your controller settings, remember that the drive replaces the gearbox. If your engine gives as an example 13hp 12 500 revolutions / minute, it will give less power to 11 000 revolutions / minute and less power also has 13,500 overspeed. This is why it is important to find the perfect weight to exploiting the right diet throughout the opening drive. This needs to be mounted longitudinally and flawless. Too light pebble send you over-rev and will not have your well drive close, however, a too heavy roller you too will close your window the drive, and you will not be able to achieve the power system.

Choose your grammage before purchase.
