variator speed-up kit Naraku 16mm for CPI, ATU Explorer, Baotian, Generic, Keeway, Nova Motors 50cc 2T KIT.NK800.06 fitting for Keeway Matrix 50 SMTX005002 2015, 3 PS, 2,2 kw

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 assembly, 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 spacers, discs with 0.1, 0.2 and 0.5mm thickness. Dimensions of the sleeve 16x21x37.

For use in tuning variators please measure the outer diameter of the installed sleeve beforehand. This should be 21mm.
