Twinpot Brake upgrade on 78 Skunk

[salty_monk]

Sorry about that. A load of them hit my box all at once. Emptied out some space. Paypal works. I will send you a PM. Dan

Sent you a pm to order two brackets, think your box is full. How do you prefer to receive payment?

[salty_monk]

Bill - you are out of PM space so I will leave this here just in case:

Says it arrived when I tracked it. In a small flat rate box.

Yes I have some on the shelf. No issue with the alternate wheel as far as brakes or rotors are concerned. ZG1000 - make sure they are the twinpot not the earlier singles

Those appear to be the right rotors but if going new you might find one for the CBR F4 which has the right bolt circle. It doesn't really make a difference it's just moderately easier to just open the holes up to 8mm rather than using the spacer as a template to re-drill them.

The bracket kit includes all the brackets & spacers you need. (Rotor spacer acts as a drilling jig, bolts to the CBR rotor & then plunge an 8mm drill or eq right through)

You need:

Twinpot Caliper & pads.
CBR Rotors
M10 x 40mm (preferably fine thread but course will work) bolts with nuts for each side.

Fit all bolts with blue loctite.

Salty, these are for sale now.
I have a 78 GS750E but will be have a 82-83 GS1100 (19 in) six spoke rim installed. Any considerations with that?
Also have a line on nice ZG1000 calipers.
What is included in your set? Mounting brackets I know. Rotor shim plates?

I have some more powdercoated black as always. I sent you a PM.

I have them on mine, you'll like them!

Salty, was wondering if you have any more adapters available for purchase.

Hi Willie - posting this here as your PM box is full. - Dan

Here you go:
Calipers
2 x calipers from various bikes, mainly Kawasaki models-
EX 250 Ninja 1988 to 2007 (single caliper on right side)
EX 500 Ninja 1994 to 2007 (single caliper on right side)
ZL 600 B1 Eliminator 1995 to 1996
ZR 550 B1/B2/B3 Zephyr 1990 1992 1993
ZX 600 C1-C9 Ninja 600 R 1988 to 1996
ZR 750 C1/C2/C3 1991 to 1993

Suzuki also used this caliper on the VX800, GS500 and the GSX1100G

CBR600 Rotors. F3, F4 & F4i. The 296mm dia ones. If you send me any links to ones you are looking to buy or pictures I can quickly tell you if they are the right ones.

Looking good! Thanks for the picture

[salty_monk]

Responded to your PM. Are you sure those rotors are 295mm? I think they are 274mm dia ones in which case they won't work. The Suzuki rotors usually used are the ones from the GS550E (it's a single brake model but you use two of the same rotor).

If those Suzuki rotors are the right dia (I vaguely remember there being a T model slotted Suzuki rotor that might be 295mm but I've never seen them personally) then a washer under the head will solve your issue or use the later bolts. You can probably even cut those down as long as there is adequate thread left.

Here's a pic of the Suzuki GS550 rotor in place.

i have read through this and must have missed something but I just bolted up discs from a '83 GS750 and everything looks great except the bolts bottom out. I noticed the disc mounting surface is thinner than on a '78. Do I need a spacer or shorter bolts?

[salty_monk]

Reminding people that on the 80+ bikes you need to cut about 4mm off your speedo drive dust cover:

[salty_monk]

Yes I've not seen it cheaper than that for new OEM.

if you need Pistons the 250 had one caliper on it up to 2006 and the pistons are likely to be decent on most available in my experience.
