1978 GS1000 Complete Engine Overhaul With Mods

That's kind of a bummer.

Did you make any progress on the engine work?

We'll have to look into how to get the dual calipers on your spokes.

Hey Mark,

How did the work go on Saturday?

Make any good progress? Would be nice to see that "1000" on the road for the ride..

I pulled the entire front end off Joe's '80 GS1000L so I could go dual caliper but I think it is a wash. I am not putting L forks on my bike and I want to keep the spoked rims. I am not sure I can go dual with the spokes. If that's the case I will stay with a single disk brake up front.

Get a wheel of a GS750 if you can't find a 1000 wheel, they are the same. i have a set of spoked wheels with perforated dual discs from a '78 GS750 waiting to go under my Kat.

No engine work. I overslept really bad so we only got done just that.

Ahh then it can be done. I have the rims. They are what is on my bike now. So maybe I have what I need then off this front end to do it. Other than the one fork. I will still need E or H model forks so as to get the caliper mounts on the other fork.

Still right where we left it. All the money has been put down, but there is no time. I don't think I'll be seeing my GS this year. At least not until late.

[Hoomgar]

Well it isn't a lot but we got my piston kit in and the block will be sent out for boring this week. The head should also at least be started for the porting and polishing this week yet. If this goes as planned at this point I should have my bike then within the next few weeks.

Not quite. The 750 rims are steel, whereas the 1000 rims are aluminum. I've put the 1000 wheels on my 750. 8)

Getting closer. Who is doing the machine work for you?

Joe has an independent who is a machinist that does a lot of his work for him. He uses the Yamaha dealer and a few others when he has to but he really doesn't trust anyone like he does the guy who is doing my block. I am picky at times so I always make Joe take the long and expensive routes to do things for me. No shortcuts or substitutes. I want it done right

Good things come to those who wait. Have patience. I did.

Mobetter was asking about the 1085 kit we are using. I told him you had already done it so maybe you could post in here how it worked out for you Keith? Did you notice a big jump in power, performance? Any ups or downs?

Just picked up on this thread and was curious about what you've learned about converting to dual discs with your wire wheels. Been thinking of doing the same with my 79 GS1000N. I like the look of the wire wheels and also the slotted 1980 discs. So far what I understand about this conversion is that you need both lower forks legs from a dual disk E model (not the L model) or maybe a G model will work, however they are slightly different. Obviously you need the calipers too. Is the valving in the master cylinder the same or not? It looks as though the front hub is machined to accept discs and should be a straight forward conversion. I am I on track here or not?

EDIT: Going to post this in the tech area
