ALL OF THIS RB CARB MOD INFO,AND I CANNOT FIND ANYWHERE IN THIS FORUM THAT SOMEONE HASN'T TRIED A FLATSLIDE MIKUNI.I AM A NEW 02 220R OWNER,FIRST TIME KAWASAKI OWNER,AND HAD NOTHING BUT MIKUNIS IN THE PAST.THE PARTS FOR THESE SEEM MORE READILY AVAILABLE.THE RB CARB MOD INFO ON THIS FORUM IS VERY GOOD AND WILL PROBLABLY CUT DOWN ON ALOT OF TIME SPENT AT LEAST ON INITIAL BASELINE JETTING RECOMMENDATIONS.THE MIKUNI AND KEIHIN CARBS ARE PROBLABLY MORE SIMILAR THAN DIFFERENT.I DO NOT HAVE ANY KEIHIN TUNING KNOWLEDGE.ALL OF MY EXPERIENCE ON MIKUNI FLATSLIDES HAS BEEN ON STREET,THEY TEND TO BE FAT OUT OF THE BOX,AND YOU DO NOT WANT TO GO BIGGER ON CARB BORE SIZE ON A STOCK ENGINE WITHOUT PLANNING ON SPENDING ALOT OF TIME TUNING.I AM CURIOUS AS TO THIS TYPE OF SWAP,BUT I AM TOO CHICKEN TO GO OUT ON A LIMB AND BUY A CARB.SOMEBODY LIKE AOC HAS TO HAVE HAD A GOOD CARB LAYING AROUND AND TRIED THIS.BUT FOR ME I WILL PROBLABLY, EVENTUALLY FOLLOW SUIT ON THE RB CARB MOD.I'VE GOT SOME SUSPENSION TUNING TO DO ON MINE THAT WILL TAKE PRIORITY.MY.02.
