Glad you guys are already on this topic. Just got my '98 bird in May. Previous owner has 2 Bros. mono exhaust.....full system, not slip on. Supposedly the carbs have been jetted as well. I'm guessing between the 2 mods boosts the hp about 10-15, to about 180. Is that realistic, or optomistic?
Also.....my mileage SUCKS compared to what you guys are gettin'. I'm averaging about 26 mpg, even when I slow down to the speed limit. My buddy has a Busa & he's gettin' 40 plus mpg, and he rides the same way I do. He's also told me on several occassions he's seen flames shooting out my exhaust when I'm revving high & pull in the clutch, &/or shift. He says it looks sweet. Is that normal, or have I got problems? Also periodically have black smoke coming from exhaust when I nail it after not having got on it hard for awhile. Another friend told me that's normal.......just carbon buildup from not running hard in awhile.....True???
