hey all; i'm new to the forum and have a 1995 katana 750...it runs alright but has a somewhat rough idle and cuts out sometimes unless you ride with the choke on for a couple of minutes, which may be normal, i dont know. but someone at work yesterday that rides mentioned having the carbs jetted, so i was wondering what all this entails, how much it costs, what parts/kits i need to buy and who i need to talk to about it locally as far as mechanics to actually get it done; any help is appreciated! thanks
