For sale-2 Yamaha KT 100 2 stroke racing engines. The first engine has been balanced & blueprinted by Russell Karting in Kansas City, is on a Burris jack shaft with a Horstman wet clutch. This is a serious race motor designed to turn 9,000-14,000 RPM & is not a toy or to be used on a back yard kart. The second engine I don't know much about, I was told when I got it that it ran & was a good motor, it would be a good "spare" motor. I also have an assortment of different pipes & mufflers which is how you tune them to run on different length tracks, plenty of extra oil for the clutch, some assorted small extra parts, & the electric starter needed to start it. Alot of money was invested in this equipment, I will take $500.00 firm on all of it together as it is something I just don't use anymore. I will not separate these item so please don't ask.
