[@TheGalifrey]

You could try a flange and spring retention system for the exhaust to reduce vibration transmitted to the pipe, it's the way the race bikes do it, solid pipes always crack.

[@ferrumignis]

I was thinking the same, but also if mounted on springs perhaps they could rig up a lever and cable to pull the pipe out of the exhaust port a bit to help that initial pick up problem.

[@Tom-Lahaye]

Use the ball joint system with spring clamp, separate 2 part ball joints are for sale from Rotax to weld on the flange and the pipe, hook up with springs and the cracking must be solved as this allows for much more flexing and moving. Also very easy to swap pipes without risking your studs.

[@ferrumignis]

@@Tom-Lahaye Ball joint style connections introduces a very unwanted increase in pipe area and volume which will impact exhaust performance on such a highly strung two stroke. Simple slip fit joints with spring retention have been used successfully for a very long time.

[@arminseifert8639]

@@Tom-Lahaye I agree, I had a Rotax on a microlight ,it had exhaust springs and rubber mounts to cancel the vibrations.

I'm amazed that they went for the rigid mount pipe at all.

[@user-IveVandewalle]

I remember that my dad's supervisor, who used to do 49cc 2 stroke tuning for competition engines in the late 1960-ies, told the story that after one heat they've lost at least 500 RPM due to bearing wear. They indeed casted their own cylinders. I also remember my dad (now age 86) told me the story that when one arrived at the job with a new 49cc moped,....it would be tuned by the racing bunch when you went home in the evening.....whithout you knowing! I'll interview my dad about all this...a heap of history is getting lost quite fast! 😉 Keep up the good work, still wearing my 'Say No to Camshafts' T-shirts too!

[@johnwest7993]

I was on the pit crew for a drag racing car, a fueler. For my birthday, without me knowing, our mechanic took my 350 Honda 4 cylinder, ported and polished the heads, tuned the carbs, tweaked the valves and timing, and switched to a rear sprocket with an additional tooth. What a difference! It nearly jumped out from under me. Scared the shit out of me at first.

Mount the exhaust on springs at the head (flange bolted to head, springs attached to flange). Rubber mount the chamber before the stinger. Good luck.

[@shaneeverett-mh1sw]

Hi loving the effort all u guys put into your quest for the record. We had the same problems with our RC boats cracking the exhaust pipe. Our fix was to have a flexable joiner on the header pipe to the pipe, we used silcon hose with an inner tube same diameter as the header and had different lengths to help with tuning. Our extended length of 52mm was the sweet spot for our set up. We also changed our mount to the end of the pipe on the small pipe diameter with a flexable mount to help with vibrations, no more crack pipes. hope this is useful. GO FOR MAN!!!!

[@pgrcadventures1414]

Hey @2STROKE STUFFING, Been a long term lurker and decided to comment with a really useful tip for sealing the exhaust. I use PC-Fahrenheit high temp epoxy between the flange and head. At first you may think it will never come off but believe me it works exactly the way you need it too. It sticks and seals at high heat but when you need to take the exhaust off you just need to a give it a little tap with a rubber mallet and it will pop off. I use this method to seal the exhaust pipe on my little 17cc helicopter nitro engine.

[@AuMechanic]

Getting closer to the target. Re spring mounted exhaust. There are a few benefits of it, one being it reduces the chance of a broken exhaust and it also makes it quicker to get the barrel off to fit new rings in in the pits between races. But the number one benefit of it as that it reduces vibration at the cylinder head as the vibration isn't reflected back into the cylinder and head, and its a know fact that engine vibration in the cylinder head will cause a drop in power. So if for no other reason than power output you need to isolate the exhaust with spring mounting. TZ Yamaha engines had a pair of O-rings at the header spigot to seal that further help to isolate vibration too.

[@maxpat82]

For your pipe cracking all the time: I had the same issue with my honda RS125: I was cracking the pipe every race weekend or so (4-6 session max) I resolve the issue by "normalizing"/anealing the steel after my repair/welding. cook it at 500F(I used my bbq) for 30min, and cool it down slowly. worth a try!

[@PetefromSouthOz]

Moving in the right direction. Male Female connector held on by two springs. It's the proven way to connect a Hi RPM 2 Stroke Pipe.

[@benpeirce2531]

I raced gokarts for years and used springs to hold the pipe in place. Like they were saying on race bikes.

[@SuperBlubben]

When it comes to using a damper to lessen the vibrations, you would most likely need a pressurized damper body! We often think of liquids and oils as non-compressible, but in reality they do compress, the amount is just extremely small, and on top you have the seals that are compressible. Therefore you always have a small "deadzone" in a none pressurized damper, but using a pressurized damper body, you can remove that small deadzone. This is one benefit from using a monotube damper design with a gas bladder or separator piston, but that benefit can also be achieved with overpressure in a twin tube construction, easily achieveable by installing a schrader valve. Another thing that could be worth trying, is placing a balast weight somewhere on the engine as far as possible from the axis it rotates around, to see if changing the characteristics of the vibrations have any positive effect on the cavitation or aeration. Best of luck to you and the crew, I'm super excited to follow another adventure across the pond!

On R/C boats and some planes we use a silicone tube between an exhaust stub and the tune pipe. Precisely because the vibrations destroy stuff.

Yeah with nitro EGT is much lower - this is probably 1000F+ at the exhaust port, so you'd need a very special material for that.

24:40 lol I see this all the time with gravity fed water systems... The smallest bubble can create a blockage, the flow of liquid takes the bubble down but the bubble wants to go up because that's what bubbles do, everything locks up. It s an air lock in the fuel line, flush the lines and reroute the lines with no upward flow only down, your lines have ups and downs . I've seen this issue moving fluids on huge gravity fed water systems... ten dudes standing around scratching their heads, lots of water and no flow , pressure reads good but no flow....one little bubble will plug the line.... Drain everything and send the fluid all at once without any air pockets if you have to keep the ups and downs in the line but avoid anywhere air can get caught in the line.

There is a comment on here about knee shelves, which i cannot find. I think this, combined with foot rests that point the riders toes backwards will help with aero. Pilots feet are like boat paddles, very noticeable when he mounts the bike without gear. Eta 45:06 for foot view

[@jimdale9187]

The bike is dangerously difficult to get rolling, as the steering is limited to about 12deg in either direction, and you cannot shift weight for balance. Knee shelves or any other hinderance to putting feet out would not be acceptable. As far as aero drag from feet, it would be great if that was our biggest problem. Protective boots do not flex much at the ankle, but at least the feet are in very dirty air, and maybe not as big of a problem as they look. What we really need is enough reliability to get in two good runs in a row, and a good tune on the engine.
