Re: GSXR 1216 - which FCR carbs?
On my 1216 w head/cams I tried Mikuni RS 40's as well as FCR 39's&41's. Bike had a true 4-into-1 Vance&Hines SS pipe,the 41's made the most power up top followed by the RS40's. If you don't have a ported head/cams then go with the smaller size carbs. Can't tell ya about jetting as it's been 20yrs since I sold that bike.
The experts will be along soon enough to offer their opinions
