Tell me about your fuel injected EVO
I have a buddy looking at a 98 Road Glide and it has fuel injection. I seem to have read some negative comments about the early FI models. Is this one of them? What happens to them to make it such a pain?
MM injection overall is a OK system but not perfect, a Evo in it's stock form or mildly modified works fine. Just like in the mechanical repair business, you hear about the failures but never hear about it not failing.
Common MM failures:
Engine temp sensor failure, bike usually runs rich and runs irrattic, high idle stays on longer
Loses it's idle, intake temp sensor has oil and dirt on it, cleaning repairs it
Loses it's idle, Ecm loses itself, reset it by pulling the fuses
Loses it's idle, last 2 items listed need done together
Engine shuts off, usually a crank sensor failure
The not so good:
Age takes it's toll on the system
Locating a tech to work on it if your not mechanically inclined and labor gets expensive if someone starts throwing parts at it
Fuel filter is in the tank and around $70
The good:
15 year old systems out there still rumbling, installed up to 2001 on TC's
Carb replacement is not a difficult task with this forum's help if the MM becomes undependable
Several tuning devices available for the 1998 MM
If your buddy loves the bike and gets a good deal, don't let the MM make his decison for him, the 1998 is a good year for the Evo big bikes. Estimate around $500-$600 parts for a carb conversion if needed

96 Road King FLHR/I, I bought it in March with 5900 miles on it, now it has a little over 11000. Put a Ness Big Sucker, B&E Superflow mufflers, Revtech DFO to manage the fuel, Andrews EV27cam, Mustang seat and a few other odds and ends. I'm still playing with the DFO, trying to grt the best setup, seems a tad rich under quick acceleration. I cut off the crossover pipe and welded up the holes to make it duals. Sounds good and runs well.
I've replaced all the sensors on mine in the last 25,000 miles.It has 114,000 on it now.It's been a good one.

My '98 has 97,000, never any MM issues even with mods giving me 80+ HP. Most of the supposed problems are hearsay or the result of ignorance about the system. 97bagger's post is a good one.
