vario bushing -NARAKU- speed-up kit 20x38mm for GY6, Kymco 2-, 4-stroke vendita lampo

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. So before mounting, 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 washers!
The kit contains the open racing variator sleeve and 30 spacers, 10 washers each with 0.1, 0.2 and 0.5mm thickness. The dimension of the sleeve is 20×38, the inner diameter measures 14.10mm.
When using in tuning variators, please measure the outer diameter of the installed sleeve beforehand. This should be 20mm.AI-translation
