Looking at 1979 SR650 disc swap

Thanks gorack I think I'm just gonna concentrate on the front for now. However when I get to upgrade the rear brakes I'll definitely take your advise.

Thanks NONB but the parts bike I was looking at got too expensive. Seems like its good business to snatch up these old bikes and chop em up for profit.

Thanks for the advise Retro Rocket.

Thanks Aesop, checked out some of your threads, look forward to seeing more of your project.

Thanks PLUMMEN thats the direction I'm heading.

Thanks vach I'm trying to buy those calipers and splitter. Wish me luck.

Thanks OnkelB, I've been reading up on things and will be looking for a 5/8 master. I am looking for a dual disc setup. I'm watching one on ebay thats at $50 + shipping, thats for both brakes, lines and a splitter. Do you think thats decent ballpark price?

Being that I´m in Europe I´m probably not the best person to ask about price - doesn´t sound too bad though, certainly less than I paid.

$50.00 that's about right. the rotors can be expensive though.

The SR rear rotors are scarce as they were only shared with one other model.

So,
I have a 1979 kz 650 C.... triple disc with mags and want to switch to spokes.... the front are pretty easy but all I have to do with the back is get the setup from a 1000 or 750? What years are the 1000 and 750 compatible with rear spoke disc and will covert to my bike?
Any help would be awesome.

So I've been lurking on eBay and I finally got a rotor and a caliper, I waiting on a splitter and lines. The thing I'm having trouble finding is the 5/8" master cylinder that I was advised to use. Is there something else I can use? Something off a modern kawasaki bike maybe? :S Help

I'm using a 96 GPz1100 master cylinder with 83 GPz750 calipers and 79 KZ1000 12" rotors, on my 79 750 twin.

Yes, you can use a later model master cylinder, just look for one with a mirror mount and dual disk brakes.

If I could get the front wheel traction, I think my bike would do a stoppie.

Not that I particularly want to though


Edit:


The splitter sucks, that's what makes them so hard to bleed. I ran dual stainless lines from the master cylinder all the way to the calipers. They were easy to bleed.
