Hi guys, great site and lots of info. I did a search but didnt get an answer so here it goes. I have a 94 600R. It runs strong but carburates poorly, ie. doesn't idle well, stalls when the throttle is chopped etc. I was wanting to know if and or how a 38 mm mikuni flatslide pumper would work on my 600. It is completely stock. Also what other carbs work on these bikes. I know the knew pumper carbs are the rage but I want to keep the cost down. Would a standard Mikuni non-pump flat slide work well? Is 38mm enough or is 40 the minimum. Lastly, when changing carbs, how do we go about adjusting for the difference in intake and air boot diameter differences. Any help would be appreciated. Thanks.
