Ok im new to the forum and i have a 1980 kz750 e/h ltd. I got the 4 carbs off the bike and all a part. Had a shop tellin me the carbs look real good for sittin for 12 years but the o rings and floats need replacement which is fine but there is some kinda idle adjustmen screw on the top thats covered and has to be drilled into carefully to show the top of the screw. There kei-hin carbs i wanted to throw the stage three jets right in once its cleaned and use new single air filters for each carb. I cant find the damn oil filter on this bike. Is it a internal filter cause it does not seem to be external and i want to install a oil cooler since its a aircooled engine. Plus a inline fuel filter coming off the tank since there is not one now.
