Anyone ever balanced the carbs on a honda cb500. I cannot for the life of me see any attachments for the carb tune. Did look on YouTube someone using water in plastic tubes but no help atall. The honda is a 97 model. Regards Joe.
Don't know if it helps, Joe, but when I were a lad and carbs had throttle slides and bugger all air filtration, we would use lollipop sticks or long matches balanced under the slides, and then watched as the throttle was slowly opened to see which stick moved first and then the carbs could be adjusted as necessary. Because of where the fulcrum of the stick was in the intake, a very little movement of the slide would produce a much bigger effect on the other end of the stick, so it was pretty accurate. Fuel/air mixture was another problem entirely.
Vacuum ports should be on the inlet manifold not carbs themselves. You can make your own manometer with plastic tube but use light oil rather than water for a more stable signal.
Try to answer the lot here at once. No screws atall on this bike. And i just want to get both carbs equaled. The right side cylinder seems to stammer under three thousand revs or does not pick up. The bike rides but is a bit scary till both cylinder are operating. Regards Joe.
Joe, I suggest you have a look at the CB500 site here http://cb500.forumotion.com/forum Very helpful people even though the search function on the site isn't very good. The watercooled CB500 - great wee bike by the way. I've had mine for years.
Flay and peeps thanks for the advice. I have actually joined the honda 500 forum. Yes quite helpful peeps. You know those little 500's seem to be quite robust and hardy. I will tell you more after winter. Regards & Thanks. Joe.
