I found one dynoport 2in1 on ebay, but its price with delivery will come out as a 2 month salary in my city.
I am ready to buy the dimensions of this pipe, the whole tube will not fit me anywhere.
well, the idea that I will get the dimensions and start making pipes and selling is pointless. there is no one in Russia to buy them except me, and it is unrealistic to send them to other countriesIf I can't get the dimensions, then I'll try to come up with something myself, looking at the photos and roughly using the dimensions.

I use a translator to communicate with you, and he doesn't translate technical terms very correctly.
1. Using a 2 in 1 exhaust adds a lot of power at low engine speeds. it turns out an exhaust with different lengths and it works like a power valve on modern 2 stroke. and it is very possible for a snow bike, the presence of power at low speeds.
2. I want to get drawings (drawing, plan, draft) to weld the exhaust myself. if someone has such an exhaust, then you can ask him to measure the length, thickness at different distances so that I can make a copy.
or , for example , a calculation table . something like this, only with the point of connection of two pipes into one.

Dyno port , moto fast sold 2into 1
or Look for pvr here & give them a call.
Thanks! I wrote to them, maybe they will give the exhaust dimensions.
And in our - your party there is no such exhaust that would take off the size and I made it? -
Kevin Hart herrjugsracing.com sent me this:
4mil crank, 2x795 pistons, bore, hone, play port gaskets, seals Sleeper cool head 4 mil domes 2 x new Banshee cyl Tell me the correct exhaust configuration for these parameters. dimensions or drawing, I will weld it as I need.
Maybe someone has had the experience of using one resonator for 2 cylinders? this option greatly increases the power at low RPM, but you need to choose the right place to connect 2 cylinders into one. Thanks. -
But I can't find the exhaust system for this engine in any way. I tried to make one resonator for two cylinders like a snowmobile.
with one resonator, the motor accelerates well to 5,300 rpm, blunts from 5,300 to 6,000 rpm, accelerates perfectly after 6,000 rpm. how do I beat this power failure from 5,300 to 6,000 rpm?

this year, the first thing we decided to do was get rid of carburetors, which turned out to be very difficult to set up for driving in winter at different temperatures.
quickly made the injector using whatever was available. it works and starts perfectly! -
Hello everyone The Banshee Snowbike project continues. it all looks something like this.

Tuning exhaust pipes in my city, no one will make me, and from the ATV they will not fit. this season we will ride these pipes, and in the summer we will increase the volume to 472, put an injector and send a moped where the thread for making exhaust pipes. everything will be.

thanks! I plan to contact Kevin for porting and other tuning.

A good option for buying and installing bolt-on?
Can I waste a stock cylinder up to the size of 68mm? what is the maximum diameter possible with the stock bore of the cylinders? It is possible to make new cylinder liners for any diameter and make new pistons for these liners.

i never seen any banshee snobike. how do u put a trak on there?
This is not a Banshee gathering. I use a Banshee engine, a yamaha rz250r motorcycle frame, a Honda cr250 fork. To install the track, I completely make everything myself, starting from the suspension levers and ending with the sidewalls. from plywood, these are just layouts, they are cheap and easy to cut with a laser. It remains to understand what to do with the engine. how to get the maximum power with a minimum investment of money.

Good afternoon. Greetings from snowy Siberia! I started building a snowbike based on a Yamaha Banshee engine. What improvements do you recommend for the maximum power / price ratio? I somehow see the installation of the crankshaft +7mil and porting the stock cylinder. or use the Athena lshe 392cc?
I want to achieve the maximum torque and the maximum length of it. Which option do you think is best suited for snowbikes?
Tell me also what is different about porting Dyna, play, drag?

I was unable to contact PVR. their Facebook page is closed. wrote a letter https://dynoport.com /, maybe they will answer something.
"where did you get the pipe spec's ; you made?"
I calculated the specification of the pipes in the program, the screenshot of which is above. I also measured the exhaust of a snowmobile, factory banshee, my ktm exc 300 motorcycle and made something average to my engine volume.
"Did it do it with carbs & injection?"
I change the fuel injector settings, but the failure remained at 5600+- rpm. then I redid the exhaust pipes and the failure went away, but the traction on the tops disappeared. it takes a lot of time to make a new resonator every time, I want a proven option right away and already configure the injector for it.
"You could have them cut the 2into 1 off & send it as a small package if thats all you need?"
No, I need all the dimensions and 2 in 1 and the dimensions of the entire pipe to the end. completely.
and also tell me what ignition timing angle you need to put on such engine modifications as mine. I have already bought a plate for changing the ignition timing angle.
