Twinpot Brake upgrade on 78 Skunk

I'd rather move them as a whole package. Let me see if I have more than 1 set - possible!

Sounds good.

One more set gone today.

I have a handful left & one whole kit incl some 2006 Concourse Calipers (grey) & some of the 7 button lightest rotors that work for this mod.

Do you still have the rotors? If so, how much you want for them?

Yes you could shim it out... I may be able to find a shim of the correct thickness.

Well sh1t, that's not what I wanted to hear. Well back to Ebay I guess. Thanks for the quick reply Chuck78

I believe you must've gotten rotors off of an ABS model... non-ABS models are what we need. Sure you could shim it, but I'd opt for finding another rotor with that same directional pattern.

I just received a set of rotors that are supposed to be off 96 VFR 750. One is offset 17mm, the other is 14mm. Is this correct? I had assumed they would be the same. Can I shim them out to be equal? Thanks

Got my brackets yesterday - a day after my birthday, cool prezzie! thanks Dan. Cant wait to get them fitted, it will be some time over the next couple of months whilst I've got the bike off the road for a couple of other winter jobs! Will post some piccies soon!

[mainiac]

Right, about 4mm I think. I am slowly gathering things for this mod. thanks for the confirmation Salty. I will be contacting you soon about brackets if you have any left.

[salty_monk]

Yes and no.... You need hub spacers to get the right offset as well.

Just read this entire thread last night. Lots of good info. 97 VFR 750 rotors re drilled with a jig will fit on my 78 750 E, correct? Can I use one of my old rotor for a jig? Thanks.

[salty_monk]

Very nice. Got any pics fitted? I can't say I'm too worried about weight on the GS but I do have one of the slotted rotors fitted (from a 1980 from memory)

Rear that I'm running:

Much cheaper to run the 1 piece steel snowflakes or whatever may be the lightest of the stock gs 275mm rotors to replace the monster 295mm 77 rear discs. The metalgear.com.au rotor is awesome though (pic)

[Chuck78]

1977 rear discs need seriously upgraded, a 295mm 12 lb rotor is extremely excessive! Downsize to a 1978+ rotor & caliper hanger, or fab your own caliper hanger and have a machinist make a rotor adapter to fit a rear modern rotor around 260mm diameter, and a similar tokico 2 piston caliper from a GS500, Zephyr, etc. This would save substantial weight, but is all custom.

Look at Rickman rear calipers for how to get rid of the brake stay. No need to ditch them, really. Even tons of modern sport bikes run them still.

I'm running a newer 275mm front right floating rotor of substantially less weight on my rear.
