Had a chance to run the full mod this weekend. It fired right up and I put a race tune on it. Ran around 180 and was getting 7:30 no problem with tons of top end. Bottom is nice and smooth for buggy, after it gets off of the bottom it rips. Very pleased with the engine. I was running a ninja and I would say this motor makes more top rpm. Very pleased. Great job Ed!! Lots of people were asking about it.
