vario bushing -NARAKU- speed-up kit 18x37mm for Minarelli 2-stroke online

Description

Variable tuning set for original variators and almost all tuning variators. The speed-up discs can influence the length of the variator sleeve: An extension usually improves the acceleration and a shortening increases the top speed. Before mounting, therefore, be sure to measure the length of the original sleeve and then change the dimension of the speed-up sleeve accordingly with the help of the discs!
The kit includes the open racing variator sleeve and 15 spacers, 5 discs each with 0.1, 0.2 and 0.5mm thickness. Dimensions of the sleeve 13x18x37.
When using in tuning variators, please measure the outer diameter of the installed sleeve beforehand. This should be 18mm.
Attention!For Minarelli engines, the tuning set can affect the function of the kick starter pinion. A strong shortening must be compensated by adding the washers behind the variator.AI-translation
