very nice engine for the price.... however the stock timing is very odd and somewhat limiting...it has extremely high crank timing as well as transfer timing, but very low exhaust timing.... the connecting rod is also very short......chrome on the sleeve was very easy to cut, crank hardness was average....fit and finish are excelent
