1985 Yamaha FZ750 - rebuild

[Guest]

Coming together Nicely GK. That rear shock is filthy though. And if experience is any indication, those shock linkage bearings are probably done and the shock is more than likely ready for a rebuild. How many miles are on it?

Hello Sci.......

Yes it's going along, but at a snails pace, I have no reason to rush or hurry on this one, the GS is up and running, so this is a project that can be done over the long run, I would like to get her done before the riding season is over to at least try out the bike, but we shall see..

As for the shock, I have no idea if it's good or bad, or just dirty, I have never taken apart a shock so that will be an experience as well, if it's easy to do I will go for it, if not, I have one on the other bike, it looks really clean so it might be in better shape.

How many miles, you ask.....gauge shows 58 thousand something or another....

I am sure each and every part will be looked and changed or rebuilt as required....

Cheers

My take on that shock is not as bad as Sci's.In my experience leaking shocks are usually pretty oily,that looks more grimy to me.Most OEM street shocks are not rebuildable unlike they're dirt bike counter parts.

This is good to know, Thank you SVSooke....

hydraulic clutch cleanup

hydraulic clutch cleanup

Well tonight I found a bit of time to clean up the hydraulic clutch system. After seeing what my buddy Spyug found, and the headache it cost him, I wanted to be a bit proactive and completely pulled it all apart, cleaned it all up and when ready it will all go back together, and I will know it should not give me any grief.

Now I forgot (shame on me) to take before pictures, there is one in an earlier post on how dirty this area was, and it's more or less about as bad as what Spyug had, however the piston did move back and forth via hand pressure, so it was not as bad and it was not stuck....Seals all seem to be good, no pitting in any critical areas, so it should be good to go.

It will need some painting, but what part won't......

And a few pics....










Piston is not bad at all




I hate pitting, but at least this is not a critical issue and does not affect the function, it's only cosmetic, and once the parts are put together it's not even seen.




Fairly clean on the inside, I will admit I did clean it up, but really it was not bad...




Seals are still good, lucky me, I can just reuse them...









all the parts.....I think it needs to get SS Allen bolts for sure...

 

[spyug]

Looks good. I'm glad you decided to start there. Its a nice easy pieces to cleanup. Are you going to stay with the gold paint? I shot mine with some black for now just to cover it. I am thinking that come next winter I will haul out the engine and repaint it all. Maybe then I'll put it back to gold.

So are you going to get stuck in with the frame next?

 

[GateKeeper]

not sure on the paint scheme as of yet, wouldn't mind the gold, but all black can be just as good, but that is not original, it's sort of why I did not strip it all off....

Work on the frame, no, not yet, there are still many other little bits to work on, radiator and fan, alternator, frame for the headlight, rear sprocket, front forks and so on.....

Little bits and pieces, then I will get to the big items, might even do the engine and carbs way before I get to the frame,,,,then again I should do it now and let it cure while I do the rest of the parts, that actually makes more sense, now that I think of it, it's more or less the way I did the GS.....

.

 

[spyug]

I just looked again. What happened to cause all that pitting in the sprocket cover? That is mighty strange. I don't think it makes any real difference but it is odd.

You might also want to take the Dremel tool and put a brass brush to that cylinder bore, it still looks a bit grotty no?

I thought you would do the frame as you did last time. Give it some time to set up nicely before things get bolted back on.

So what do you figure, back on its tires by Aug.? Sept.? next year?

 

[GateKeeper]

Yes I don't like the pitting either, but am not too worried about it, once the slave goes in it's all covered up and you can't see it, however I think there is damage to the cover itself, not pictured, but it seems there is a part broken, or torn up by the chain or something to that effect, again one cannot see it as it is on the inside so I am not going to worry about it.

I did take the Dremel to the cylinder bore, but since my brass brush was almost down to nothing it didn't do a great job, however I did take some 2000 grit paper and went at it with that, so the bore is actually very smooth, it just looks discolored.

Yes I should sand and wire wheel the frame and prime and paint, and let it cure, while I do all the other items, it would be the way to go......unless I powder coat....LOL

I am still sort of on the fence on that....

If I don't procrastinate and work on it at least a little bit most nights, I should have her back on the road before seasons end, I would like to take her for a spin while the weather is still good...

The only thing I will probably not have done to my liking is the body panels and body paint, she just might be naked for her first test ride.....

I will have to go and get some wire wheel brushes for the drill, and the dremel if I am going to get at that frame......

and sad to say....I went Turkey hunting this morning, and unfortunately came back empty handed, but it was nice to be in the outdoors even if it was a wee bit on the chilly side......

Cheers

Well just a bit of work tonight, nothing special and nothing major, but every little bit gets it closer to completion....

so it was a bit of varsol, rags, wire wheel, and it came out clean, needs more work, going to give it a satin finish, since it's not in a perfect condition and it will be a good way to mask the imperfections....

a few pics....

Cleaning

Cleaning

And so the cleaning continues....

Just getting the crud off a bit, all the parts will be completely stripped down and cleaned properly, but it gives me something to do and it makes it easier to see the parts and what condition they are in...

for example the front forks require new seals one of them is hacked up a bit

and so a few pictures....

Front_forks

Front_forks

Tonight was an easy night, it's too hot and humid to be working, but with a beer by my side, and a bit of determination, I thought it would be good to disassemble the front forks, get them cleaned up, get rid of the old oil that is in them, and put it all back together.

well the first problem was they are off the bike, and the top caps are on good and tight, since I don't have 3 hands, or a vise, I had to call on the neighbor to help me out. I held on tightly of the tub, he used the socket and we managed to loosen off the caps, once loose I knew I could get them off, and off they came.

Took all the inards out, drained the oil, poured a bit of varsol down the tube shook it around and drained that as well. Next will be the rest of the shock to come apart, as I do have to take the seals off one is ripped, but before I dismantle them all the way I have to check to see if this needs to be done, no sense in doing more work than is required, but then again I can paint the lower parts and not have to mask off anything,,,,well I will see....

So a few pictures of tonight's work, and I even included the first part that has been cleaned and painted, you will see it right at the end...

 

[harley10]

you do good work and your quality is top notch, Brian

 

[GateKeeper]

Thanks Brian.....

I am trying, that is for sure, I always, well most of the time, told myself, if your going to do something do it right, or just don't do it at all....

I don't like things to be done half Azz'd

ya know...lol

Frame

Frame

It's been raining most of today, but caught a bit of a break, and since everything was wet outside anyways, I decided to give the frame a spray of Simple Green, a wire brush in some areas, and just a baby bottle brush for some of the tighter areas, then it got a good blast with the power washer, and left out in the sun for a bit to dry off....

Neighbor across the street came over for a bit to see the progress, and mentioned he has a portable sand blaster, just needs to be hooked up to an air compressor, and sand......well I actually do have access to an industrial air compressor, and sand at the local Princess Auto, so maybe by next week I will sand blast the frame, the rims, and the exhaust,,,,ohhh ya, that will save me a lot of time of standing in front of the wire wheel, you gotta love good neighbors.....

And a few pics of the now squeaky clean frame.....












Just after putting the frame back in the garage, I took off all the nuts and bolts cleaned them on the wire wheel, took off the center stand, but I have decided to use all new SS Allen head bolts and nuts and so on, at least I now they are not going to rust, and all will be nice and new, now I just have to go and figure out what I need....

Cheers
