Pe---that seems a little weak to me for a 100cc class engine. A good 106 or 110 better pull harder than that. I have a 25x12x3 just haven't tested it and will probably sell it. I was told to use a 26x12x3 by the manufacturer, the 25 he states is to small. If I have time I will check it this week and report back. I bet mine will run right along with the 116 on a similar set-up and be 2.5+lbs less.
