Will these GS850 front calipers fit on my GS750?

Got some weird/serious carb blues if you’re curious, it’s in the fuel/carb/exhaust section. I now realize I’ve never had parts that I was suppose to have inside the slide.

That last post was forever ago!

It still runs runs and is a little more refined, I replaced the bearings on the swing arm, broke the bleeder screw on the rear caliper then destroyed the threads trying to tap it out, there’s a used caliper in the mail now. I discovered my front right caliper is leaking from the piston area. My kick starter doesn’t won’t engage, and the shifter is not as smooth, for example when you push down into first it just kind of sticks there and doesn’t spring back until you barely tap up on it.

I bought a nice new stator, after hooking it up I realized the previous owner had not connected the rectifier and stator properly. Also, I have no fuses, which I didn’t even think was possible but there’s nothing there. I’ve melted two starter buttons, and think my bike is a very good candidate for an m-unit. The bike looks almost completely stock except the v&h and pods. The original turn signals look great and the new seat cover is very close to OG.

So basically I’m running around trying to put out fires everywhere on the bike, however I do believe I’m going to have some fun riding this Spring, otherwise I’m going to throw it in the river! ��

Sometimes at night I look at classified ads of mid 90s GSX750 Izumas for $1,300 and wonder what in the world I’m doing, then I tell myself I’m going to be much cooler ��

I’ll get more pics and video soon, I’m actually looking forward to the cosmetics now.

Don't worry she was already warm before I started it

It's been two long years

Here's the bike as she stands, waiting for some needle bearings and race for the swing arm so I can put the rear wheel

Got the bike started tonight but it's pouring oil profusely from the upper left cam cover. When I started it first I didn't realize the cam cover bolts were loose, so I sequence tightened them but it's still pouring oil.

here is a picture of the new garage neighbors

Yes, this is how they all are as far as I know.

Finally figured it out; the starter wire was sodered to the starter relay, is this normal? Guess I have to buy a sodering gun now.

so yeah it turned over, sprayed some starter fluid and it definitely was trying to start, there's no gas going to it currently.

on to the turn signal relays

IMG_0567.jpg Yeah my bike is quite rusty like this. The ground for the battery box is a holding screw for the starter relay that i couldn't get out after using an impact.

im seriously thinking of just getting an m-unit instead of fighting ever screw and bolt.

Well, a lot has happened since April, the VW was in my garage till July preventing me from getting to the GS project.

The good news is I have a much larger garage with 8 other people, kind of like a co-op garage, it's basically an old warehouse with bays. It's got a bathroom and other comforts my old place didn't have, plus several large benches.

So, I got my carbs put back together with nice new pods.

Then I tried hooking up the battery, not as much luck, I melted the starter button. I know now after reading some old threads that the battery box is not grounded.

My problem is I can't remember exactly how it was rigged up and it's definitely been changed by previous owners. I'm confused about the twin places on the starter relay that have Phillips heads screws and what goes there. I do remember a wire being welded on the relay I think.

Also the yellow/green wire coming from the starter switch is just hanging out near my battery

Also since the previous owner has changed wires up, what exactly is coming and going from the fuse box? All I have is a yellow wire someone taped off with electrical tape.

any tips or suggestions?

I suspected the spring went inside the slide arm, I was just thrown off by the picture of the spring under the needle, thanks for the clear up.

In other news; I bought a VW Passat and changed the rear brakes, I got some cheap calipers and the threads on the bleeder nipple are gone after trying to bleed the brakes, so now the car is taking 75% of my garage up and I can't get back to working on the bike until I have enough money to buy genuine VW brakes in about two weeks.

That's a bummer about the bleeder nipple. I've been waiting for one of these one way valves to arrive in the mail, then I'll do the braided brake lines on the KLR. Last time I bled them I felt it was likely that the threads would strip so hoping to avoid that.

On another note, similar to your garage situation, my son's car is now in my way. It runs but he works nights so mornings before it gets hot is when I really like to work out there and I have to shuffle vehicles around.

Just look up the VM carb rebuild tutorial manual put together by a GSR member, I think it's linked on the main GSR page (not the forum but the actual GSR front page)

EDIT - Brian Wringer's GS page... not GSR. But you can't see the inner part of the slide where the spring sits!
Good manual to have anyway:

No that's not correct, it would be under 22 or 23 in that 77 750B diagram, like THIS:

I have both styles of slides, this spring in question is only for the jet needle, & is not needed if you have the earlier style carbs. Not the spring in the rocker arm, that one is on every VM rack of carbs. This spring in question is only on the later style of VM carbs.
