Hey mate, i would say they would work very well if the guy thats tuning it is good, flatsides are quite difficult to set up well but when they work there excellent, i use Keihin FCR's on a 1100zzr engine in a radical clubsport that i help run n they do a hell of a job. Mite have a higher idle speed as well, are you using the bike on the road?
