Just bought an 89 that stumbles off idle but runs great above 1700 rpm. Any and all suggestions about this are appreciated. Thanks!

Welcome to the forum and glad you already found an answer to your issue. Do you know when your timing belts were last replaced? This seems to be a critical item.

Welcome from the northern tier of PA. My first wing was an "89". Enjoy the forum and ride safe.

Welcome Thomas. Over and above the belts, I'd get the carbs cleaned and synced.

Timing belts were replaced at 45k. As far as getting the carbs cleaned and synched, any truth to the stories I've heard about Honda dealers refusing to work on Wings of this vintage?

Most dealers won't touch a bike over 10 years old.

Thanks for all the replies. I can definitely 'ride around' the stumble while I search for an independent place for service.

Welcome to the group from a current 89 rider. I've lived around the low end stumble even though I don't like it and don't see an easy way to get around it except to play with the throttle a little on take off. My smooths out once I come off idle. I run seafoam once every month or two keeps it running smoother. Mine Wing has just over 148k miles on it and the belts were changed this spring, that did add some git up n go to the bike too.

Timing belts have less than 10k miles and it really does run very well above 1,700 rpm. The timing advance looks like a good project for this winter. Thanks for all the info and thank you all for the welcome!

Check to see if there is a X stamped on the lower frame near the right side foot peg when you are sitting on the bike. The 88 and 89's had a recall on them for this problem. The low speed jet needs to be changed from a #50 to a #55. The "computer" that controls the engine was also replaced. My 88 did not have this done. I just replaced the jets and made sure the carbs were synced and it solved the off idle stumble. I am still using the original "computer" in mine. There is also a change in the routing of some of the vacuum lines to the carb. It is a jetting problem, not a timing problem that causes the stumble.

Here is the Tech bulletin from Honda on the recall. It says that this was just for the 88's, but it was later revised for some of the early 89's also. Just worry about the jetting change.
