alternative carbs

HI,ANYONE TRIED ANY DIFFERENT CARBS? MIKS ETC [NOT CHINESE PLEASE] CANNOT SEEM TO CLEAN MY BUGGERS OUT PROPERLY [VIBEY BATH THING NOT DOING IT] I KNOW THE ORIGINALS ARE NOT AVAILABLE ANYMORE,ANY HELP MUCH APPRECIATED.

Just as a replacement or for performance?

Andy, I would also be interested to know. Not really bothered about improving performance, but what would be a simple bolt off / bolt on replacement? I dont think theres anything wrong with mine that a good set up wouldn't cure, I'm just trying to get it running well enough to ride it to the local dyno shop (BSD). Do the racing guys use different carbs or are they restricted by regulations?

Despite my research over many years there are no easy options, It can be done but if you take a look at my track bike project thread you'll see it's not easy
As I understand the racing guys are limited to a couple of jet sizes up or down from the standard size.
Regulations are pretty strict, but that's to keep the costs down and the racing close.
