These stock appearing engines are very fast. I sold one of the sister engines to Reed Open on here and he was very happy with it. One is an old style engine and cylinder with a TS Racing big bore Alky carb and the other is a new style head and cylinder with a Buller atomizer carb that sat on the pole at the UAS Nationals a few years ago in Ohio for the special Yamaha class they ran. 500 for the old style and 850 for the new style. The old style has 0 races on it only startup time on the stand and the new style has just the 1 race in Ohio.
Yes it was. It was faster than 24 of the UAS entries and that was 100 lbs over the UAS weight. It was also 21st quick among the 67 karts that were there. If i still had a driver i would be running it some place.
