Hi, good to find a home so to speak, been riding Kawasaki 6xxers since I bought used 1979 kz1300 in 1981.. I have had 3 voyagers 86,84,85, I have a 84 that was totaled during a tow job, (slung ) pissed me off but I think they were madder when they had to pony up cash to cover. I HAVE STRIPPED OFF ALL OF THE bags , fairings, and I can not for the life of me get the fuel infection to work so I am going to install the carbs that I have, Unless of course this is just not feasible. I am reaching out your group to see if any one has done this to a degree of success. I am located in New ENGLAND. What I am wondering is this fuel injection and ignition system tied together or can I run carbs, I know I would be stepping back a little, but I am not that interestyed in rippin it up on this bike , I have many others that are better suited for that, gpz 900 turbo, 1000r ninja, so just looking for a looker that is an oddity, not a bobber but I do have an eliminater (600) and have had a 900,1000 in the past and I like that type of look. Any & all suggestions are welcome..

Hello and welcome to the forum.

It would be unfortunate to scrap that F.I. system on your bike. If you were to obtain the Kawasaki fuel injection supplement manual, you could probably sort out the issue.

You don't mention what is wrong with the bike.

A little more info would be helpful. Does the bike start at all? One of the first items to go is the fuel pressure regulator. A pressure gage on the rail will tell you if that is working up to par, should be around 36PSI.

I have followed the wiring diagram,schematic, although It has been a while, replaced dfi with a known good one which worked for a short period of time and then failed. No signal to activate fuel pump, I hate to purchase another without knowing what is the cause, I am going to go back to the tracing of the circuit, I need to bench test the dfi box that I have well two of them.. I do have a set of carbs off a 1981 kz1300 , Id come across DG 6 into one exhaust which I did have on my 79 noit sure these would fit the 84 but I am looking into this at this time, I quess stepping back into a set of k&n with the dg exhaust would be a trip down memory lane but I know the dfi gives out a hp boost , 20 horse power if memory serves me right. thanks

Hello Sixpack:

Some suggestions.

1: If you have a processor not providing pwr to your fuel pump, I would make sure I do not have a fault (Short) in the F.P. circuit. Maybe you have already done so, but sometimes these issues are at the pump (Or particular component) in the wiring, and not the processor.

2: You should be able to send in your processor to a company called CARMO. They are in the EU and they have tested my ignition module in the past. (About a year ago) They specialize in testing and repairing out of date modules and they may be able to test your box. They can repair at the board level so this may not be a lost case just yet to retain your injection system. When they tested mine, they gave it a clean bill of health and only charged me for the testing fee.

Their email address in the US is This email address is being protected from spambots. You need JavaScript enabled to view it. I had to send my ECU to their USA rep in the S.F. Bay Area, he in turn sent it in to the Netherlands for testing. Their shipping was quick and at the time, they were responsive to my questions.

Hope this helps.

The Fuel injection system provided 10 more HP over the carbureted models. 130 vs 120.

Another maintenance item that needs to be adhered to on these fuel injected bikes is a Battery Tender.

They are a must in keeping proper voltage going to the processor. Also performing proper battery maint. is a must with these early F.I. systems.

Never jump this bike, take the battery out and charge it, or replace it as needed.

I recall several dealerships telling me over the years they used to replace these processors due to bad batteries, and from stray voltage from jumping. The voltage regulation system in these early bikes is not too sophisticated.

If you battery is lead acid, make sure the electrolyte is at the right level, or just go with an AGM battery. (If you have been following what has been going on in the battery world lately, I do not trust Lithium-Ion yet)

Regards.
