the first question to ask was it a mobile dyno? and the second question is did the person running the dyno know about running two strokes ?

only ask because i ran a stock 350lc on a charity dyno and was told on the print out it was 102 horse at the back wheel


57.6 hp sounds about right to me. my 21 with the gps splice air box ect ect ran 60.1 hp
