I figure on my poor ass early 20s budget I won't do anything to drastic.

Haha that went out the window.

So I recently ordered a twin pot ZX6 caliper adapter kit from Satly_Monk over on GSR. Should be able to stop me a hell of a lot better than the big ol' single pot.

As for the rims, I need to order spokes. I had a friend give me a quote and while I am planning on taking them to him for trueing the constant bills are keeping me from having him lace them up as well. May as well give it a shot, I dove into the engine no problem.

I have a job interview at work today so hopefully I will be able to get on full time, that will free up a bit more cash to go into the GS.

What spoke brand? I've been told to shy away from eBay spokes.
 
Re: '77 GS750B, "Hahn" Black Borranis

No way in hell would I use spokes from eBay, I was thinking Buchanan. Not sure yet.

I was quoted $90 per wheel for spokes and $250 labour to have them trued and spokes fitted.

But then a portion of that $430 could be used on tyres if I do it.

Edit:See Underlined.

Good to hear. I've seen people say things like, "They are just spokes, how much different can they be?" Haha very different, obviously. I'm splurging on Buchanan's as well.
How about you lace them yourself and have them final trued at a shop and then have them install the rubber too? I'm going to have a go at lacing but the tires will be going on by someone guaranteeing their work. Cause all I can guarantee with myself and tires is a tire iron smacking me in the face and jacked up fresh PC. Haha

O shit that much for just trying them? Seems like a lot, right?

$250 seems alot to have your wheels trued, is that down the Goldy?

I had mine done at ' Ashs Spoked Wheels' for $70 per wheel. I just fitted the spokes myself, quite easy to do. ( the f,n truing is not)

Does great work, the only problem is he is in Brisbane.

Cheers Patak.
 
Re: '77 GS750B, "Hahn" Black Borranis

I adjusted my last post to be a little clearer.

It is 250 for lacing and trueing for both wheels. Which seems decent to me.
When I spoke to the previous owner he recommended Ashs as well.

I asked the local Honda dealership just for a laugh the other day. I think it was around 700.
 
Re: '77 GS750B, "Hahn" Black Borranis

Lace and true the wheels yourself. I did it on my GS1000 for the first time and it wasn't that bad.
This truing/balancing stand is pretty sweet. They have 3 really good videos that show you how to do it. I relaced and trued both of my wheel, then took it to a pro($20) to check my work.

Re: '77 GS750B, "Hahn" Black Borranis

Really glad I stumbled onto your thread. I am just starting to rebuild my 'basket case' GS ... and it is also a '77.

Interesting as my rims are completely different from yours with respect to the manufacturer. Perhaps because my bike was built for the Canadian market? Dunno.. are your rims OEM?

Love this thread!

(if you have a chance head over and have a quick read of my thread...)

Re: '77 GS750B, "Hahn" Black Borranis

I pay $45 / wheel to have rims laced and trued here in Toronto. There's a guy who all the vintage racers use and he knows his shit. I've had 6 sets of wheels done by him over the years for various projects, all with Buchanan stainless spokes. I suppose by now it would have paid to have learned to do it myself ;) $90 each time always seemed like a no-brainer to have it done professionally. That's been spread over 7 years.

At $250 a set, I'd have learned to do it myself I think, or kept looking for a less expensive wheel guy.
 
Re: '77 GS750B, "Hahn" Black Borranis

$300 a wheel here! $600 a set!

If my rims were pre-drilled I would definitely have taken the time to learn. Hate being in Australia sometimes...

Wow man, those prices are brutal.
 
Re: '77 GS750B, "Hahn" Black Borranis

So I have lined up a set of GS550 forks for the bike which means I will be able to use the dual disk setup that a GSR member came up with.
This project is still going but at the pace it is moving the snails are laughing. Ohh well, that is what I get for attempting to "do it once, do it right" build.

Ohh and I left my phone on the back of my ute whilst I was fishing..... So buying a new phone took a bit out of the budget as well. On the up side I should be getting full time work soon enough so I will be able to finish things up a slight bit quicker.
 
Re: '77 GS750B, "Hahn" Black Borranis

Hey Brodie, this thing is looking great. I need to get some more pictures and info up about my 77 GS750 build. Looks like a lot of the stuff you did and plan on doing are the same as what I have done. Let me know if you need any parts - I have a ton of stock, aftermarket and custom made stuff lying around for our bikes. A buddy of mine is a really great machinist and he is currently making me a one off aluminum triple tree. We save all the files and templates for all the pieces and brackets.

I am currently working on some rear sets. I made up some brackets and I am piecing together the linkages and rear sets from a 2006 GSXR 600 and a 2004 GSXR 1000.

It seems like you are an experienced builder and know what you are doing, but if i can save you some time or cash on your build let me know.
 
Re: '77 GS750B, "Hahn" Black Borranis

Thanks JK. I was watching your thread for an update. How did you go with sorting out those passenger pegs?

The bike is moving along slowly. I start my new job on the 10th of June so after that I should have a bit more free cash and time to put some love back into the bike.

I think my next move is going to be getting some spokes and lacing the wheels my self. After that I will have a go at getting them trued up.
 
Re: '77 GS750B, "Hahn" Now with Showa!

Picked up the new forks tonight. Turned out to be a bit more than I expected. Got them for a steal as well. They have a "476 Showa" sticker attached to them, I am going to assume that is the weight of the GS550 as that is all I can find from limited research.

Anyway here are the pictures to show that there is actual progress being made on this bike.
I really want to ride it so I think there might have to be a stage two of this build, once I can afford all the things I want.

Re: '77 GS750B, "Hahn" Now with more Showa!

Dual caliper mounts = good. Not "L" model forks with the leading axle =even better.

I'm guessing they are 35mm, about 30.5" long (center of the axle hole to the top of the upper tube)?
 
Re: '77 GS750B, "Hahn" Now with more Showa!

Have not had a chance measure them yet as I am away from the garage. They are 35s though, checked that out before I bought them. They look a little shorter than the stock forks though.

Forgot to measure them before I ripped them apart. By sight they look 2 inches shorter than the stock set.
They are off an early model GS550 if I remember right. Was bugger all oil in them as well. Which I also forgot to measure before I ripped it apart.
Thank god I have a Clymers and a Haynes.
 
Re: '77 GS750B, "Hahn" Now with more Showa!

So I have been moving along slowly with the bike in the past few days. Slow progress is better than no progress.

I just "pressed" the new bearing onto the lower triple and thought I would post up a couple of pictures of how the powder coat turned out on the triple and fork lowers.

On that note, despite my best efforts the powdercoaters managed to get blasting sand inside the fork lowers. I was going to give them a turps bath for a day or so to get the sand out but I am not sure if this will mess with the powder or not. Has anyone found a good way to clean the inside of fork legs without killing the outside powdercoating?
