Two weeks ago I bought a Tsk from a customer of mine who didn't use it. He told me it had been used maybe once in the last 5 years. It literally looks brand new. And it runs even better. It is absolutely insane how fast it is. However, the speedo is not working and I'm not really sure how fast it really is. One thing I will say is that there is a 65mph road that crosses the lake and I am keeping up with or passing those cars on the road. Could this be anywhere near accurate. A 65mph Tigershark 770?
