Up for sale is a tony kart krypton I think it's a 08 or 09. It has a 99 stock moto engine from shark shifter which has been balanced. Engine is very strong and competitive. Engine is also practically brand new. It has less then 3hrs on it. Kart chassis is 32mm. The seat stays have been welded and and one of the tubes right below where the fuel tank bolts up. The welds don't effect the chassis and is normal to weld the chassis over the life of the frame. I've only raced it three times once before the new engine. My second race with the new engine I got second out of my class. Sale is also coming with a kart lift stand so you can transport the kart with ease. If you have any questions please don't hesitate to ask.
