I have a bike that I picked up as a project bike. Title and frame are 1992 cbr600. Looking a little closer, I saw that on the side of the engine it says 893cm^3. Does this mean that this is a 900rr engine or is there some other way to tell what engine is in this thing? Also I would like to know what size of jets to put in the carbs as I rebuild them. Currently it has 160 for mains and 40 for idle. It has individual foam air filters and a 2 brother slip on pipe.

Were the carbs the same between the 600 and the 900? Looks like they took a hammer to part of the frame by the top of the carb to get the carb to fit.

Thanks for the help.

ps. I posted this in the 900rr area also, not sure where was appropriate to post, so if a mod wants to delete one of them that would be great
