A new racer bought an older kart with a supposedly freshened kt100. It has what appears to be a Horstman Steel Nytro fluid clutch. (there are no stampings or castings on the outside, but it looks like other Nytro clutches). A little searching makes me think parts will be hard to come by. Does anyone have insight about this clutch and if he should decide to change it for a dry clutch does it have any value?
