Hi,

is it possible to replace CV carb for flat slide kind? Is it good or bad idea? Will motor take it?
 
On what bike? What size carbs? Short answer yes, but the more info you share at the start the better this community can help you. And they do love to help.
 
Race track use, flat sides are great. Around the street, normal driving, not as good as a well tuned CV carb.

CV carbs, when working properly, give better low RPM and throttle change performance. Flat sides can bog on large throttle changes. Racing is mostly large throttle conditions, not stop and go traffic....

Fuel economy suffers too with a flat side.

It like asking are racing slicks better then regular street tires?

The answer depends...If you are on the highway in a light rain, racing slicks are awful....

If you are racing, racing slicks are perfect for the job.....
 
Replace it with a VM series round slide mikuni and be done with it IMO (vm 32 is probably the right size although youll need to research that)
 
Round slide are a better way to go and there not bad price wise . I'm still learning them but VMs seems straight forward and not to bad to learn !
 
Yup - Mikuni VM. 34 seems to be the one of choice, but I haven't found jetting info for the SR250. Good to replace the CV carb on the 250 if you're faced with replacing diaphragms etc. as they get expensive.

$100 or less for a stock VM34 new, and then you'll need some jets/needles maybe a slide depending on what is recommended.
 
I run flat slides on my bike. first off there way more adjustable but that kinda means there are more wrongs and still only one right. The anwser i will give is if you decide to go flat slide get real ones not hundred dollar mikes xs or oko pwk copys.

Dunno about that. My VM Mikuni has so many ways to tune it that it can your head spin and SUPER easy to tune.
