fuel injection mod? 1980 GS850GL

[arcturius]

Not sure about all the dirt models, but I am reasonably sure that all the GS-series bikes lost their points and kick starters going into the 1980 production run.

Typical of some manufacturers, though, there might have been a few hybrids to get rid of the last few left-over parts.

.

I can confirm that the 1000ENs still had points, and mine definitely doesn't have a kickstarter.

I'll be watching this thread; I was just thinking the other day that I'd use the GS as a test bed to learn the megasquirt before I do more tinkering on my MR2.

1980 and later...electronic on gs 4 cyl. models.

Kawasaki throttle bodies for one of the later 600s fits our engines.

Sorry to resurrect an old thread, but does anyone know if any of the following throttle bodies will fit right up to a '81 GS850?

05-06 KAWASAKI ZX6R (Ninja i think?)
07-08 KAWASAKI ZX6R
06 07 SUZUKI GSXR 600 750
04 Kawasaki ZX 636

Thanks much.

No.
No.
No.
And No.

The only bodies that will fit right up are the GPZ1100s, and only a certain run of them.

Will any of those work with some effort? I found 1 set of GPZ1000s on ebay and they're $400.......... I think I ready that someone managed to put some GSXR600s on a GS1100 with a bit of elbow grease. Is the spacing on the 850 and 1100 much different?

Spacing shouldn't be much different, if at all. You may have to switch some boots around, but you could probably get them to fit, but you'll definitely need new boots as your old ones are probably not flexible enough to jame the TBs in there.

The answer to this question is this:

Probably all of them will fit, but not all of them will fit right in.

With projects like this one (which is intriguing to me) you might be able to use a lot of different things for a starting point...the process of making all the parts work together might be where the real work comes into play.

Good luck!!

No offense, but what is it that you are trying to accomplish? While an 850 is a great bike the added aggravation of adapting fuel injection to your existing intake setup won't really make it any better. Check into a Dynojet kit, pods, and a header. You won't get any better than that.

What do you define as better? I'm also working on a fuel injection setup, and if done correctly it can run better than even the most perfectly tuned carb setup and it'll gain a little power in the process.

Even before I read this thread I had been thinking about a long term proj that would be a gs1000 with gsxr1000 throttle bodies... Haven't done anything more than the "dreaming" part of the build, but it's exciting to think about.

You don't wanna use GSXR1000 throttle bodies. You want to find a set that were on a bike with a similar HP output to yours that way the injectors don't need to be replaced.

I was just imagining it so far.

A very basic FI system that actually works will in fact be MUCH better than a Dynojet kit, pods, and a header. Why? Ease of adjustment, adaptability, easier to add OTHER upgrades down the road.

There's a reason the industry has started going to FI for MOST newer bikes. It's because it's better.

Not to mention it will ALWAYS be perfectly tuned...not just perfectly tuned for the weather and elevation that it WAS tuned at.

I agree that a correctly done FI system would be far superior to a carb setup.
