I have rode motocross all my life. I recently bought my first street bike, a 97 Katana 750 with 11k miles. The bike has to be choked slightly to get started and takes a while to warm up, I think I can fix this with a washer on the needle or an adjustable needle. My main problem is a flat spot between 3500 and 4200 rpm, after that it pulls really strong, I'm not really familiar with this type of carb and was wondering if it was a jetting issue. It has a 4 into 1 slip on under it and a Honda silencer?? (I'm not sure how that happened, it was like that when I got it). I am also checking the compression this evening and changing plugs, if there are any suggesttions on the best plugs. Any insight on this bike is greatly appreciated.

a very good cleaning never hurts either. with a 4-1 exhaust it might already be jetted. a 5* advancer is a simple upgrade too99% of the questions asked here can be answered by a 2 minute search in the service manual. Get a service manual, USE IT.

Shimming the needles won't help warm-up time . But it MAY help the low/mid rpm weakness ....
Best plugs are stock plugs . NGK JR9C .
Has the bike been jetted ? Check it out . Many just turn screwdrivers and hope for the best . Also look at the bottom of the slides to see if they've been drilled/tapped . I had to fill mine in and re-drill them the right size because of the aforementioned .

If I were a betting man, I'd say the owner took the jet kit out of the bike and sold it seperately before you bought the bike from him.90% of motorcycle forum members do not have a service manual for their bike.

Maybe they think it means pooOriginally posted by soulless kaosbut personaly I dont see a point in a 1000 you can get the same power from a properly tuned 600 with less weight and better handeling.
