Why would you open the throttle bodies full of brake cleaner directly into the valves/cylinders ?

@zenzeypher 24 күн бұрын

Argh the more I watch the worse it gets

@Extra-Medium-Skills 17 күн бұрын

Haha thanks. Don’t worry, I didn’t wash the cylinders! But I was soaking the buildup around the butterfly mating surfaces. That buildup was causing the throttle to stick closed and not open smoothly. Just after I shot it with cleaner, I used a light abrasive pad and cleaned it all out from the throttlebody walls. Much smoother operation now!

Wow. Why do you think the extra 15cc gave you so much more power?

@Extra-Medium-Skills 28 күн бұрын

Making the engine more efficient with a brand new surface on the bored cylinders combined with the 13.5 to one compression ratio made a huge difference. More air and fuel were allowed in and was burnt more efficiently. Additional 15 cc were added to the bore, which made the motor more over square. Check out my later video titled “the battle for first” and you will see how much stronger this engine pulls than a stock motor with a jet kit/exhaust…. Even when I was turning this fat 180 section tire!

Thanks so much! The geometry is something I need to do a better job of explaining, for sure. Basically minimizing the input of the arcs to keep the deflection of the stroke to the minimum. If I think of a way to explain it better in a video, I will do so!

Thanks much! I think you should try racing. I believe my average time at Hallett is 1:39 At track days & 1:37 in races. Both CMRA and Legion have their own license programs. But since both are AMA sanctioned and offer reciprocity, you can use your license to hop into a race in either organization if you want. I think you should do it!
