Twinpot Brake upgrade on 78 Skunk

[salty_monk]

Those are the wrong calipers to work with this setup. You need the pre 1990 ones.

Yes you have to space those rotors out from the wheel to work with this setup. You need the offset. You re-drill the holes in the honda spider to fit the GS in between the original holes. The size of 295mm dia is important.

This is what the correct caliper looks like, although you need a pair.

Thank you very much for the responses.

Could you please tell me the reason newer designs are disqualified?

Or, what is the most important reason you recommended the circa '90 parts?

Is it offset? Is it thickness toward the axle? Towards the outside?

If I'm OK with making a bracket for the caliper anyway, is there a reason to disqualify newer calipers?

I'm just trying to figure it out! I don't want to reinvent the wheel, but I know I will at the minimum be making a single-plane caliper adapter. At the max I can envision making a 2 plane (offset outwards/inwards to the wheel) adaptor.

[salty_monk]

You should be able to space the rotor far enough away from the wheel & make a stepped bracket if you have full facilities.

The method here is just the most economical way of doing it. Originally it was designed to work with STOCK GS550 rotors so their size & offset limits options. I put Honda CBR on later.

2 of these left now..... I found another powdercoated one. Come get them, I doubt I'll be getting any more unless 20 or so people get together for a bulk buy.

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.

Nice Ride; that baby's CHERRY!

[salty_monk]

I have had a clear up in my garage & found 2 more sets. No bolts left though. I do have hub spacers.

Dan

[Henway]

how thick is the spacer?

[salty_monk]

Depends on the bike.... Your 83 probably has a wider triple than the 1000.

2 sets left now.

Anyone know the part number on these EBC rotors?



Is it MD1003 or MD 1014??

EBC Catalog

Aha thanks. Catalogue I have doesn't give all those details just dia, bikes & part no. Interesting.. the latest catalogue give 1014 as a 296mm disk & I don't believe those are 1003's as he hasn't re-drilled the holes just enlarged them.

Cheers,

Dan

[sschering]

I think you are right on the 296mm.. The brembo charts i dug up match on all aspects but the diameter..

[salty_monk]

Perhaps it's a typo in the chart... even has 296mm standard in the title when they list that part for the F4
