You can tune it to make it nearly perfect (with different springs, etc), but I'd rather tune a non-CV slider. CV carbs are terrific for cold starts and smooth riding, whereas non-CV sliders are more race-oriented.

You probably knew all of that already.

Thanks for the video, Weld.

Indeed I already know "the theory"

The carburetor I have in mind is this one:


Or page 8 from their catalog: http://www.koso.com.tw/Actions/downl...19db3ed99b.pdf

These can be purchased for about $60. I used Koso dashboard in the past so have no worries about quality. Or that these are scooter carburetors. The drawbacks I see is the lack of accelerator pump (hence the price), and the fact that they have the same carburetor both for 2- and 4-stroke engines (it even has a power jet?!), which makes me feel the circuits in them will not be very tuned. But it's a direct slide carburetor, how hard can it be to tune it?

Why, oh, why do I have to come across threads like that:

Sweet Bike! Looks similar to my Roketa DB-06, same speedometer too. Love those super moto wheels, and the sliders!
