you must rejet the carbs to work with aftermarket pipes, which if louder you need bigger jets to deliver more fuel, also, hammering affect under load is usually faulty plugs, which may have carbonized from running to lean

It sounds like you may have or will be jetting your carbs. I did this using the directions with the kit and used the Clyman manual for this bike to show me step by step how to remove the carborator. You will only need to attach 2 of the 4 hoses on your carb. syncronizer. If I remember right, you need to remove the bolt-on cooling fins to expose the engine block. The is a black screw or bolt that you take out and screw the threaded metal adapter of the sync tool. Be careful using the sync tool. Be very light on the throttle or the vacuum in the cylinder will **** in the mercury from the sync tool - not good. The problem you are stating on idle & backing off sometimes happens when the carbs are running rich (too much fuel) Hope that gets you in the right direction.

Hi, Steve and the usual suspects are:
1. Severely discharged or a damaged battery must have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.

6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.

Leaking fuel into one cylinder...first one then the other. been sitting a while. disassembled carbs and cleaned... very tarnished. one float needle had to soak out. did not disassemble diaphrams on top...


You need to take off the tops and check the slights if they are moving freely as well as the condition of their membranes.It is part 12 here [img]http://partstream.arinet.com/Image?arik=s4v92978S7HV4vH84i3c&arib=HOM&arim=PlvRPT97U4oQrvKJ304_9A2&aria=c5zpNrwMU6EBLpCPt-rB5A2&ariz=3&ariv=http%3A%2F%2Fwww.babbittsonline.com%2Fhonda-motorcycle-parts[/img]Also need to take out the number 13 part which is the cold start valve and clean it so it moves freely too. And check that cold start valve's airway to the idle jet is not clogged. Use some carburator cleaning aerosol and compressed air.

1983 honda acc cold start wont stay running when cold idles rough


try checkin your idle air control. most of the time it is a vacuumn line going into intake.pull it off and if the car revs up dont worry, it wont hurt it. if it does simply put it back on, if it dies you have a bad vacumn.
