Twinpot Brake upgrade on 78 Skunk

Yeah, I can remember a few times standing on the rear brake while bending the handlebars to get leverage on the front lever . . . I was younger and stupider then, that's for sure, but with loads of adrenaline on tap, which is probably the only reason I'm still walking.

Tom, I got the Carbtune and the "professional" Colortune, both fresh outta Dublin, UK. If memory serves, the four plugs are 14mm thread. Do the 1100/1150's have a different thread, or are the plugs more deeply recessed?

Dan, that's sincerely AWSOME!!!!!!!!!!
So, there's no need of four or six pots???
I have a GS1100E, which is your advice??
 
You *should* be able to run the exact same system but so far nobody has fitted it to the 1100.

If you want to be the first I will refund you (minus postage) if it doesn't work out. We measured the fork & it seems that everything is in the same place so I'm pretty confident it would work....

Dan :)
 
Dan & Jacora (and anyone else lurking). The kit should fit the forks on the '83 GS1100 if it's the one with anti-dives. But it WILL NOT fit the '80/81 GS1100. The bolt spacing is about 1/4 inch wider on that one.

But wait! Dan, didn't you build the brackets with an oblong hole at one of the mount points? Hey, maybe it will fit after all. I'll hafta size it up on my 1100.
 
I built it with a little bit of additional "tolerance" as I wasn't sure how good Suzuki's was from year to year....

It might well fit or if not then you could maybe open it up a little more to make it fit. There should be no real forces in the up/down plane as the caliper is basically being pulled through the forks from the back (that's the force acting on it) so all the force is shear in the opposite plane pivoted around the top bolt if my thinking is correct.

Dan :)
 
OHH MAN! I finally got my rotors! :dancing: Can't remember when I've been so excited!

salty monk you have pm

"To fit this swap.. you just need to get a kit from me, some CBR F3 Rotors & Some Kawasaki twinpot pistons."
 
You have one back... you need a lot more than that as you have a 550E. You need to upgrade to a dual front end first before you can do this.

If you are willing to mess around with making your own bracket you may be able to use a CBR 900RR Rotor & 1 Kawasaki twinpot caliper. That will give you a decent setup. It's been done before by "Suzuki-Don".

Hi,

I have been searching for a brake upgrade solution for ages.

I have a Katana. It is was a 750 but is now 1135 and is standard other wise.

I am currently fitting wire rims:

18inch front 3.5 wide 120/70 tyre
17inch rear 5.0 wide 170/60 tyre

GS Hubs
GSXR sproket carrier to provide chain clearance
GPZ off set front sproket

So I would like to fit brakes which work... I have read quite a lot regarding this upgrade and are truly impressed with what you all have achived.

So I need the following

Kawasaki calipers, going with the later model 650R.
Honda 900RR rotors
mounting kit from Salty Monk

Can anyone see any issuies here?
 
You might want to talk to Salty, or search on the various brake threads he has here to get an idea of which calipers you need. Same for the rotors, you need a specific diameter.

Good luck.
 
They are a different caliper. Might work but only if all the mounting points, pad thickness etc etc are the same. Tolerance is pretty tight.

If you weren't in New Zealand I'd say send me a set & I'll let you know... :D
 
Dan, I'm finally making some progress on my upgrade. Caliper rebuild kits took a long time to arrive. Thanks Flatout! :rolleyes:

My painted calipers are currently baking in the oven. Red, of course.

Makes me wish I hadn't given our electric range to the Goodwill when we switched to gas.
