Twinpot Brake upgrade on 78 Skunk

[salty_monk]

EDIT 11/17/2025 - Yes I have a few sets of brackets/spacers/hub spacers left - Price is $115 shipped Priority in the USA. Most other countries tend to be around $128-$140 shipped 1st class package.

Newest brackets also allow the new Ninja EX650 Tokico calipers to be fitted as well as SV650 & DL650.

Latest: - We now have a bracket for the L Model thanks to Colab with a couple of members here. - I don't have brackets yet. PM to register interest.



Just some pics of the latest on the skunk... Soon to be replicated by one Mr Tom MLC (no doubt in red!) & Mr JSkellington.

Also newer bikes (80+ you will need to chop down the speedo drive dust shield by 4-5mm.

One on the G for good measure....

[sschering]

Nice. What are those the CBR rotors?

[Tom MLC]

Received all my gear today Dan. And I scored a nice set of rotors on ebay. I hope I didn't beat out Jack! How 'bout some pics of what you did with those spacers. And also the two round cylinder thingies you sent me.

I'll post some pics when I finish the install.

[salty_monk]

Yes, CBR rotors.

Can you give us some kinda' relative idea of the stopping improvement? Your set-up looks VERY nice!

Thanks Robu

Damn...

Who discovered that rotor swap? Has it been around for a while? I can't recall ever seeing a floater bolt on before...

I have a nice set of Nissins off a gixxer that would go nice on my 82.

Good info...

Another member of the Salty_Monk twinpot conversion team. I borrowed the stainless lines that were on it for another project but you get the drift.
I have not had the bike out so i cannot comment on the braking improvement, YET.

Great upgrade

Nice work on those brakes guys. Steve, engine cleaned up real nice!
I'm partial to GS1000's

The difference in performance is "night & day". Loads more power, loads more feel. Takes it to a 2 finger brake from a "oh Sh** grab a handful" stock brake.

I worked the rotor swap out about a year ago, first changed the G over about 7 or 8 months ago & have done a couple thousand miles on it.

To fit this swap.. you just need to get a kit from me, some CBR F3 Rotors & Some Kawasaki twinpot pistons.

You can probably budget:

$30 - $50 on calipers depending on rebuild status, Ebay skills (They were used from about 87 up to 97 so it depends what year you get. Al ot of early ones need new pin rubbers although seals are generally ok).
$30 - $40 on brake pads. (I actually got one set of calipers for $30 with a set of useable pads once...)
$50 - $100 on CBR Rotors (depending on your Ebay skills)
$110 - 120 for the brackets, spacers & bolts. Depending on location, how you send the money etc.

Takes probably 3 or 4 hours to do it the first time as you have to re-drill the rotors using a drilling jig etc.

Well worth the money & effort.

Yes...Yes...Yes. Excellent stopping power! I rode Dan's G last week. D@mn! You could probably do stoppies with this rig!

Form and function: this is a superb blend, and Salty is a true pioneer. We all know these bikes have plenty of go. Now you can stop. I'll post a performance review and pictures as soon as I eliminate a vagrant air bubble or two lurking in the splitter, I suspect.

And Tom, yeah, I was eyeballing the same set of F3 rotors you picked off on eBay, but I told myself no spending until I get these Kawasaki calipers bled. Lemme know if you need an extra set of hands with the F3 conversion. I've also got a four-plug Colortune if you're interested in a carburetor party . . .

[Suzuki_Don]

Jack did you get those holes tapped out that we were talking about. Did they turn out OK?

[Guest]

Tapping new threads this weekend, Don, thanks to your advice. Both of my GS1000s have spoked wheels with hubs tapped on both sides for rotors; on one of them I had no trouble running the rotor bolts in all the way, and the Salty Monk conversion is underway, with the elderly Suzuki rotors soon to be replaced with less elderly F3 disks.

On the other wheel, for some curious reason, the bolts bottomed out after three or four turns. I've got a tap and some machine oil. All I need is a little time, and a jar or two of Steinlager to steady the nerves . . .
