39mm Keihin FCR carbs on 95' 900 RR
I am in need of jetting information for 39mm keihin FCR flatslide carburetors if any one can help it would be greatly appreciated. I have a 95' CBR900RR with a MVR 4 into 1 full exhaust and a stock motor. I asked SUDCO and they will not sell me or give me any jetting info. These carbs originally came off of a Yamaha and the jetting was way off for the 900rr. Changes have been made to them so far but still can't get them right, when you roll on the throttle it picks up good and goes, but when you hammer the throttle the bike boggs and hesitates before smoothing out and accelerating hard. Thanks

I have a quick question about boring a 41mm FCR. Do you bore the 41mm carbs? and how large can you bore it to? I am looking at maybe boring it out when I bore my bike to a 500cc later this summer.Thanks, Rob Deimn guys! Black eyed peas - Boom boom pow has blowed my brain ))) try it and write me PM your mind)
