Quick note on this topic. Have been reading in the different forums that these ignition control units are needing to be replaced, as well as the PG sensors. May give credence to having this project continue.

Can't comment on the issue; however, you have found out that not all mechanics are versed in the older GWs, and as such, you will need to be your own mechanic. You need to get the OEM service manual. Trying to determine what has caused these new issues is a PITA, especially if these were not...

Two thoughts for this post. Wide Band O2 (WBO2) sensor and cam sensors. First, is a WBO2 needed. Not necessarily. It is a good diagnostic tool and provides information on how good your engine tune is. You put together a reasonable timing/spark/ignition table to start - lets call this the...

Reverted back to paired injectors, also used semi-sequential as well. No joy, engine would not start. Kept at it for a couple of days, just went back to sequential injectors and engine started right up. Not going to beat the head against the wall, stay with sequential and go forward. have to...

Sold.

This information is in the OEM service manual. The right front and rear brake calipers are linked. To bleed the rear and front right calibers, bleed front right caliper first, then rear. The left front caliper is bled using the front brake lever. The left front and rear caliper pistons...

Have to review my for sale items; however, starting to clean out the garage. Have 1500 engine parts, set of vacuum hoses, carb to manifold boots, clutch discs, shift levers and gasket set. Going to bin these items unless someone wants these. First $50.00 USD and the shipping will come from...

For the record, this applies to any older motorcycle as the owner will certainly be the mechanic.

Back from my sister's place in Ontario. Lots of work done. My brother, Sonya and I have some 700 or so hours into the 30 year makeover of her husband's house - inside and outside. Looks good what we have done. Getting back into the ECU replacement project. Will be reverting back to paired...

Reading a lot of forum threads regarding the ’85 Limited Edition and ’86 SE-i fuel injected Gold Wings. These are, in my opinion, sought after by many. The CFI – Honda’s fuel injection system is state of the art even by today’s standards. Lots of forum threads lamenting the older carb models and...

The Supplement is the manual for the CFI system and other aspects of maintaining/working on these fuel injected models. It is a MUST to have.

Read your thread, here and on the other forum. These bikes are some 38/39 years old, have to expect some issues. First order of business is you need then OEM ServiceManual, the Electrical Troubleshooting manual, and most importantly the Supplement. Without these, you will ask a lot of...

Welcome and thank you. There are others on this and other forums who have converted an 1100 to FI. Good luck. Look forward to hearing about your progress. Here's a good read: https://ngwclub.com/forum/viewtopic.php?f=47&t=25983 What ECU are you considering?

I have started the OEM CFI ECU replacement project procedure based on minimizing changes and meeting the project requirements. The first section deals with the OEM CFI system components, what can be kept/reused, components that need to be disconnected and not reused, recommended...

My intent is to now put together a schematic for a basic install that will work and replace the OEM ECU. I had this at the start so recreating it will not be an issue. May go back to this configuration as well. Can always upgrade later on to sequential fuel/ignition, but first to change to...

Had a moment of reflection regarding this project. What I did, what needed to be done, what changes needed to be made. The ‘85/’86 OEM CFI system has all the components required for a good operating FI system and as a “package” deal, Honda made it work extremely well. What needs to be done by...

Joe - I intend to review this thread as I post to try and keep the discussion in a logical sequence. There is a lot of information in the forums regarding the '85/'86 CFI system and is helpful, but not always spot on. Not trying to dispel anyone's beliefs but there is a lot to know. May...

That would be good.

Have often wondered what is the “quadruple by-pass”. What is it exactly. Extracting the source code from the OEM ECU can be done, but there is the knowing the component data used by Honda to tune the engine. I mentioned that Honda put together a CFI system as a “package” deal and made it work...

Good morning Randakk. Thanks for reading my thread and the favourable comment. I like to think of the CFI system evolution as starting with the CX500T, a little more refined with the CX650T, then on to the '85/'86 GW FI models. The "bones" are the same but the design evolved to suit the...
