Whats a good carburetor for my DT125 with a 170cc athena cylinder kit?

@claws You'd be surprised.
I'm not going into the specifics.
But Pressure=force/area
The force is generated via the vacuum of the engine, the area is the size of the carb.
If the carb increases sizes, but the vacuum remains the same then you will see a drop in pressure. Aka, the pressure to actuate the carb will lower and it may not be as effective, sine the carb works off the venturi effect, getting this balance right is important. Going too big can have adverse affects. Is 36mm too big? I'm not saying that, I'm just saying bigger is not always better.
@Calum of course a bigger carburetor isnt always better but i dont think that i can go slower with the keihin and if i cant get it to run great with the bike i will trade it for a smaller one. but a guy that i know put a 38mm carb in his 1998 dt125r and said that it runs great. still i believe that the new carburetor will out perform the one i have now but if it doesnt i will be a bit disappointed but anyways i wont lose anything with this new carb
