mxturd Posted November 10, 2006 Report Share Posted November 10, 2006 OK I just bought my kids a KFX 90 and it is pretty slow for their taste,,but the owers manual says that there is a maximum speed reduction collar insalled on the drive train, and that only authorized dealerships should do this mod,,and that it required a special tool ,,,how can I make it faster without calling F.A.S.T. Thanks alot ,,,,OHHH and by the way it says that it will make it 50% faster WOOOHOOOO Quote Link to comment Share on other sites More sharing options...
Yamahammer Posted November 10, 2006 Report Share Posted November 10, 2006 the article i read on them said only the 50 had it on the clutch a limiting collar but could be wrong. It may just be a restrictor in the exhaust at the head pipe and head and also in the intake or carb.I would cll the dealer and ask service the special toll is probably a fly wheel puler.. Looking into geting a kx50 for my daughter so let me know how it works out for you and what it actually was. Quote Link to comment Share on other sites More sharing options...

mxturd Posted November 11, 2006 Author Report Share Posted November 11, 2006 Ok its a little space on the drive belt and all you have to do is remove it and it lets the drive belt fully engage,,,,super easy and makes them go soo much faster Quote Link to comment Share on other sites More sharing options...
