2 stroke design/simulation software . . . ?

Does anybody have any advice/experience/? with any of the 2 stroke design and engine simulation software that's still available?

All I know about MOTA or Bimotion is what's on their (Old looking) websites.

Thanks.

 

2 strokes are still being developed and the best software is engmod2t from Neels van Niekerk. What are you building??

Thanks for that!

Long winded answer: Looking into building a very light & small roadracer from scratch around a big 2-stroke single. At first, the KX500 looked fun, interesting, and all that, but I'm now under the impression that the stock transmission ratios would make gearing a pain (No alternative gears available, as far as I can tell) - and that the increased displacement is offset by a big drop in revs. Now something like the YZ250X or KTM 300XC is looking more promising, I . . . think.

Main reason for wanting the software is to play with the port timing, head geometry, and most important of all, pipe design on the computer to avoid making too many paperweights and conversation pieces. Even if I don't mess with the inside of the engine, I'll still have to fab up a pipe.

And if this is a path that has been taken before with little/no success, well, I'd rather not learn the hard way.

 

Oh, hey, we should talk. I'm setting up a 1992 WR250 for road racing as we speak.

 

The project is currently in the "I'm gonna" stage - no engine on hand - yet. The racebike will get built - just trying to settle on an engine.

 

There's a lot of work to do now...

 

:up:

 

you need Tom Turners TSR software from Ed Erlenbach. Tom retired a few years ago ....... I have a RD400 stage two hot street motor built by Tom, its insane.

Tom Turner, master two stroke Tuner, Pipe builder, and the man that developed
TSR Two Stroke Racing Software designed and built his 424cc Yamaha RD400
Dragbike to develop and prove his racing design software and prove it, it did.
Taking 49 national records and holding the world record set in 1986 for 16+ years.
Tom retired in 2010 after a long and successful career.

have fun with that non counterbalanced single in a road racer.... we just switched out to a Quadzilla motor for that exact reason.

 

Part of the reason for choosing this engine was to test a counterbalancer design.

Thanks for the TSR link - that's a name I haven't heard in a long time.

 

Oh man, awesome! Interested. I looked at the kx500 engine and couldn't find a feasible place to mount one unlike the CR500 that a guy in Australia did.
