What might be the best part is the dipshits over there that actually thought the dude was serious.

And then kept posting about how dumb he was even after it came out that it was a joke.

I didn't get far enough for him to say he was joking. I just knew he couldn't be serious...

OMG.....

When my dad was a kid he had an old suzuki 2 stroke dirt bike. He said that him and his friends used to bomb start it backwards and it would actually run...... no joke. I remember reading in a forum somewhere that if the timing was off (not sure which way) a 2 stroke could run in reverse.

Yeah, they talk about that in the thread from the OP.

There's also discussion of some 2 stroke snowmobiles and golf carts that run the engine backwards for reverse.

Maybe he was trying to race that "direct exhaust induction" vette.

I've heard of old KTM 495's running in reverse.

I have seen two strokes run in reverse. They just don't run well cause the timing is off a bit.

They posted the Direct Exhaust Induction sketch in that thread too.

I didn't get it at first. I thought the guy was serious and of course none of it made any sense. engine running Backward ?!? Sucking air out of the cylinder??? What?

QuoteIs there some sort of exhausting intake bypass valve on a DooCatti engine too?

I'm a bit slow. I had to read his post twice. I really couldn't get my head around somebody actually dreaming that up.

On a side note Rotax has actually rigged up some of their snowmobile engines to go from forward to reverse rotation on the newer model Ski-Doos instead of using an idler gear for reverse. It's seems kinda weird but it works pretty well and apparently saves some weight.

I actually got a big teary laugh out of this sneezing panda rendition used for Krispy's second reply...
