Just get to measuring, Might as well make a video of the procedure too.
Baahahahhahaha
No I'm not going to go through that procedure because I have never done it and besides I don't have an
Engine apart right now to even do it. All 5 engines are running or spares sitting on the shelf.
I just thought someone might come on here who has the quick and dirty answer.

I am in the process of copying a pipe and have rolled the first cone.
It looks like s#!+
Just a work in progress.

I have forgot the details on crankcase volumes for 2 strokes I remember doing a lot of reading on stuffing cases and came to the conclusion more gains could be made by tuning the entire Pilot/Odyssey or anything 2 stoke for that matter, steering, suspension, clutching, air flow into and out of the Engine, jetting, tire pressure, tire type, shock oil viscosity, verifying the wet line in the pipe, plug reading etc.
The gains were just not worth the effort for my applications, dyno gains do not always translate into faster, more powerful, more reliable in real world use. The people I seen tweaking engines that far trying to squeeze every last ounce of power out of them usually require a complete tear down and rebuild ever few hours of run time. Crank bearings, rod bearing new piston and rings, every 3rd rebuild a new rod. When Renni Awana came to the SODA races he changed his Engine every race day then rebuilt between race weekends, I think he had 4 spares when he and Bob Briggs came to race two of the SODA series races. Renni's engines were tweaked to the max, like a hand grenade with the pin half out. I think he was running the FL350 based engines at 465cc he definitely had his act together. A friend of mine drove his backup car one race, it had the dial-a-jet carb and my buddy had to fatten it up 2-3 clicks on the straights then lean it back down in the corners. It was a hand full of power.
Please document the pipe building here I am considering building a better pipe for my 440 ROTAX Pilot in the future and thinking about a 583 ROTAX swap into that ATVR LT Pilot I bought years ago then taking them to the desert for testing.
What are using to layout the pipe segments. I am a sheet metal worker just never learned the layout part of it but have plenty of co-workers that are experts in layout. I stayed away from learning the cone layout because I was mostly in the welding, installing and HVAC service end of the trade. Also at the time, every shop had its own layout guru, so even if I learned how would have never used the skill in practice. Reality was the layout guys would create patterns hand off to me I would use the patterns, scratch out the pattern on the metal, cut it out, roll it up, weld it together, go to the field and install the finished product.
EDIT
What pipe design calculator are you using for your pope design.
Thanks.
