Question about 1986 Honda GL 1200 Aspencade Gold Wing

1 Answer

I have an 86 Honda interstate with 1200 engine which I just replaced with an engine that has only 5500 miles on it. I completely cleaned the carbs as it has been sitting for 15 years. Compression is good, valves have been cleaned and timing checked , but on cold start, as I raise RPM to 1500 t0 2000 RPM during warmup, #3 cyclinder misfires and the backfire comes back through the carb. It appears to me that this problem was already there before the bike went out of service. Any ideas?

    Thank you to drallim for the tip. I had already taken the heads off and found the valves were sticky. I cleaned them up but with no success. I finally removed #3 carb and found the slow speed jet to be partially plugged in spite of just being cleaned. Reset the carbs and now works fine! Thank you again.

Might be a bad intake valve spring or sticking valve on #3 cylinder. Not likely to be ignition timing problem as it would affect all cylinders. You might try an oil additive that is designed to free up rings and valves, but if it doesn't help, time to go inside the head. Good luck!

1986 aspencade 11,500 miles sometimes when starting engine backfires and will not start later will start and run fine.


I suspect the carburetor needs tuned to correct the air-fuel mixture in the mid-range.It's possible that the carb
was not thoroughly cleaned and/or the fuel system upstream of the carb was not cleaned and has re-contaminated
the clean carb.

Hi, have an 86 honda goldwing interstate that wont engage. do you hve any ideas......it's a bike my dad left me and i would really love to ride it again......


For my 1980 Goldwing I changed the clutch cable as it had stretched. Also do frequent oil changes because the engine oil also lubricates the transmission. My left hand grip had also worn a bit where the pin fits so I replaced it when I did the cable.

Hello! Am having an odd issue with a 1985 GL1200. Bike sat for 5 years before I got it. I rebuilt another set of carbs (same type) and put on it. Throttle return is fine, but the engine revs don't decrease...


Go into the carbs again and clean them real good. Take every parts off and clean-clean-clean. Also make sure the the intake boots are tight between the carbs and the boot. If there is a air leak it will stay at a higher RPM for a few seconds and return to normal. To test this take some carb cleaner and spray around the boot where it attached to the engine and where the carbs are clamped. Start the engine and if spay. If it changes rpm's up or down then you have a air leak.

Engine miss at 45-55mph, no accleration with throttle response,


Anytime a bike sits for that long you stand a chance of fuel system problems. It sounds like you may need to "boil out" the carburetors and of course resynchronize them with vacuum gauges when you put it back together. You can also use a mercury manometer for synching the carbs. My guess is you have varnish still in the float bowls that is causing erratic running and perhaps the vacuum operated slides are not working correctly.
