Engine swap

Post by Mike Over »



My 1994 1500 has a bad tranny shifter forks, have found a decent engine that has come out of a 1988.

What are the pitfalls I will encounter swapping these engines. I am fairly new to goldwings any assistance would be appreciated

Interesting project, , , ,I am in no way knowledgeable enough with your project to give any advice, other than to say, , ,

If I recall correctly, there was a difference with the coils, relative to getting the tachometer to work properly. There was a three wire tach on older goldwings, and a two wire tach on the newer goldwings. The '88 engine might raise havoc with your '94 tachometer so you might need to change the wiring from the coils to the ECU/Tachometer. I don't think there is a problem with fitment of the '88 engine into a '94 but hopefully one of the guru's will be along shortly.

Good luck

You will need to use the newer style water pump and gear position sensor behind front cover on the '88 engine and while at it use the intake manifolds and carbs off the '94.

Just a quick question, why must I use the intake manifold and carbs off of the 94 engine?

I am going to swap the carbs and manifold, for my knowledge what are the differences between those years on the intake side of the engine.

I am not very knowledgeable on these bikes
Thanks

Not sure on manifolds but the 88/9 carbs were very lean with idle and off idle hesitation conditions
Search for that there should be lots of complaints although mine wasn't too bad if I warmed it up 1st

The 88/89 intakes have vacuum ports in different locations to go with external emission/driveability components. Later years were incorporated into the ECM. 88/89 carbs had additional vacuum lines not to mention cruise control/throttle devices and actuation were different.
The vacuum line plumbing is very different on the early years. :ugeek:
