Driveability issue

Postby DH955 » Thu Jun 21, 2012 10:13 pm



I have a 1983 Interstate. I have replaced the timing belts, had the carbs done (thoroughly cleaned, adjusted, and synced) and new plugs in. Around half throttle it falls on it's face. It acts as if it is running rich. Plugs in #1 and #3 show carbon fouling of running rich and to help verify richness, adding choke it gets worse. I'm not sure if it is in the timing or carburetion. Of course the '83 is somewhat of the red headed step child as a lot of things are different from year previous and year after and both the Goldwing service manual and Clymer manual are lacking in areas for the '83 models. Any ideas?

My 83 had some problems also.
Even after careful carb restoration and sync,it ran above 2800 rpm like pu-pu.
I stuck a mirror in the plenum and looked at each slide.Raped the engine and watched all but one of them jump.
Yup,even tho I was confident everything was OK...one slide was stuck...
I removed the carbs and rotated the cap 180* and tested the slide action using a shop vac stuck on the intake tube.
I still had one that was a bit sticky.I had to re-polish them again.
Before I installed the carbs,I tested each one again.
Also,pre-set the idle jets...by the book and check the diaphragm in the air cutoff valves.

Here's a post about my 83 carbs..http://goldwingdocs.com/forum/viewtopic.php?f=4&t=8928
And one with syncing the carbs..viewtopic.php?t=8994&p=40711
