Fuel injection on a 1977 KZ1000?

You all haven't run me off. I just put the bike aside for a few years and will start with the fuel injection installation as soon as I can put the parts togther. Still looking for a throttle body from a GPz1100. Thank for all the info.Off to do some shopping. I'll let everyone know how it works out.

I've considered swapping to fuel injection on a few applications, one being my CJ5 Jeep where extreme of road angles can give carbs some nightmares although the Motorcraft 2100 style carb has proved capable of a steady idle in situations I would never willingly repeat. While there are benefits to EFI over carbs it's funny how back in the day I could ride quite reliably with carbs, never felt they were a problem in the same way points ignition wasn't an issue either and yet now it seems that common, current thinking is that all these things should be tossed at the first opportunity.

I don't personally feel that throttle body injection provides a huge benefit over a set of carbs, but I'd be interested to see a system using the Kawasaki injectors, but with a better control system, there's a reason so many GPz1100's were fitted with carbs the first time they had a problem once the warranty had expired. The whole reliability of electrical and electronic components has changed so much since the 1980's that using some modern components could really make a difference. It's an interesting topic, albeit not something I'll be trying myself. How about using four of the Triumph Bonneville throttle bodies that are made to look like carbs or something similar or build injectors into the bodies of existing CV carbs that will fit a KZ1000?

Welcome back Larry,
Not that I am looking to derail an old thread but to me it sounds like you have dirty old carbs with clogged circuits.
26 mm carbs on a 77 kz1000 may not be ball buster fast like some of the others but when they are clean and tuned they work great and are "very" reliable.

Wire George can make them brand new for less then 400 bucks

Just my 2 cents

Shoot I could clean a set of carbs for darn near free.
But if I wanted more performance I would consider EFI first before any other carb type (having to buy and rebuild 28s, 29s, or RS/CR carb purchase) you come out to the same or way less with a set of throttle bodies and a controller

I don't know about free but yes you can do it your self for a lot less
For me it is a matter of economics but if I had the bread I think I would rather have WG do the next set.

This is the Winter of rebuilding carbs for me, I'm doing a set of 24's and a set of 26's
Both were froze up when I started and the 26's were painted :sick:
Beyond the free labor and cleaners I will need all the gaskets, O-rings and a can of carb dip
Then I still will be taking them to the local Suzuki/ Honda shop,( a very cool old school bunch of guys) to
have them sonic cleaned,
No idea what that is going to cost but it shouldn't be too bad.

I'm into it and don't regret doing them but I don't wish to have do it again any time soon.

I know that FI can be very dependable and if I ever find a Harley that I want to fix up it will have fuel injection
but I am not convinced that retro fitting F I a system on a 77 kz1000 is the simplest,cheapest, efficient/reliable way to go
if he wants to ride much this year.

Welcome to my nightmare :laugh:

Considering the thread is 4+ years old Im not sure it will ever ride. Still to note, the first thing that needs done is valve clearances, then carb work.

Simplest way to get riding? Nope. Most reliable, best fuel economy and power? Absolutely. Tunable to a wide array of displacements cam swaps and tunes, yup.

Did I miss it, why did it take so long?

Agreed, valves first!
