Charles, you want proof…. As in a few months back when you posted a huge self proclaimed write up on 4cycle before it crashed proving your 40 plus hp engine? You claimed it was legit because JR Racecars dynoed it for you. Then you made the mistake of posting a claim as to what RPM it made peak torque. Because of our many years of experience working with engines on the dyno I knew the RPM you claimed peak torque at sounded way off. For that reason I called our friends at JR Racecars and asked them about your engine. They told me that you called and TALKED about having them dyno an engine for you but you never sent it to them, and that they had never seen one of your engines. So, is that the kind of proof you are referring too? What others false claims do you make? You challenge anyone that comes on this site with such lines as “prove it, build sheets, specs and pics”. Please, refer to my above post. Anyone that goes out and puts years of hard effort into gaining an edge in racing does not go on line and show everyone how they did it and what they are doing. Only the people that race keyboards do this. If I were you, and I wanted everyone to believe you could build a national level no rules type engine, I would join the UAS and show everyone what you got on the track. Not with words and pictures. Then you wouldn’t have to work so hard at self proclaiming how great you are, and everyone would know it because of your on track record. Let’s face it, as long as your racing your neighbors on mini bikes no one will really have respect for your accomplishments.
