2 Stroke with a flat sided needle, and orifice through the middle of needle.
Someone did their homework. Looks like a winner.

 

Lol, that looks like a HD dialajet, but at a much more reasonable price.

1bad450r,

If you still have stock 42mm butterfly carb, how does that do in top end?
Is it a midrange centered powerband, or does it wind out to top?
I hear quick response, but haven't heard of any ways to extend top throttle range out further, if it needs to at all.

I'm thinking about putting on my rotax engine. They seem like the highest tech carb on market,
and they work well with DS650 stock intake/air box combo I hear.


Thanks!!
