86 gl1200 engine

Post by 5str48 »



Is it possible to convert a carburetor model engine to fuel injection? Bought an good 86 engine on e-bay not realizing it is a fuel injected. My old engine is carburetor. Don't like the prospect of having to send it back.

I think internals are the same. I think you can just swap everything on the outside of the block, heads over from you're OEM carb engine to your Ebay FI engine. Transmission is same too.

The block will be the same. Did the engine come as a complete unit? If so, there are some internal differences such as a larger stator. The FI engines have a 500 watt stator instead of a 350 watt. Shouldn't be an issue and gives you more power to play with, just remember this if you have to put in a new one. The Ns sensor on the FI engine is in the timing belt area. The PG sensor for the carb model goes in the same place. You will have to change the trigger plate. This is what is on the FI engine:


The trigger plate you will need is:


You will notice that this plate only has one lobe on it. You will have to change the PG sensor wiring as well to suit what is on the old engine. You might be able to leave the Gr/Gl sensor unit on the rear of the right cylinder head - red arrow points to it:


just remove the wiring from the unit. You will have to check the timing to make sure it will work if you did this - good thing to do regardless. I've mentioned these items without having seen a pic of the engine. A picture would be good for us out here in the ethernet.

Might want to confirm the FI bikes and carbureted bikes use the same Rectifier/Regulator. If different the Rec/Reg may not be able to handle the 500 watt stator....

RR for the '86 Aspy and '85 Limited Edition FI are the same P/N, should work.
