1090RR clutch master cylinder rebuild kit?

I need to rebuild the clutch master cylinder on my 2013 1090RR Brutale.

Evidently rebuild kits are not specifically available for the bike. (Dealer standard operating practice is to just replace the master at around $600 USD. Presumably this is due to liability concerns.)

The Cylinder is manufactured by NISSIN, so I assume that one of the standard kits gaskets would work on the piston, but I cannot find the appropriate diameter kits. Has anyone ever faced the issue? Any input would be appreciated.

Robert

Yes. This issue has been discussed ad infinitum before.

I believe Noel has found the correct diameter and seal parts.

Try search. Barring that, PM @theknurl.

Just a status update for those interested:

Despite the "infinite discussion", I could find nothing definitive on the forum here on which kits or seals would be appropriate for the Brutale clutch master cylinder.

The bore diameter is 1/2 inch, but there are many different piston configurations (with their attendant very different seals).

After researching the the webs (a surprising dearth of specifics!) I believe that the K&L kit #32-4142, which is spec'ed for certain years of the Honda interceptor, will have the correct seals. Once I have the kit in hand I'll post the info.

Have to agree there. Lots of things here are discussed on here but can be pretty hard to track down given the headings on the posts. Can be hidden anywhere in search.

Thumbs up ?

Usually Nissin M/C bore sizes are marked on the underside.......
Most Hondas use 1/2"
K & L Supply will have the parts kit:

Noel,

Thanks for responding.

Yes The bore is established at 1/2, but there are many different seal/piston styles that Nissan used in that size.

There are, to my knowledge, no cross references to the select the correct kit for the Nissan master that MV used, Even the photos that accompany the various kits advertised are stock photos that do not represent the actual seal types either.

I BELIEVE that I have found the correct kit number from K&L as mentioned above, and as soon as I can compare them side by side I'll report back.

Hey Robert & everyone.
Currently working on clutch issues which entailed sourcing seals for slave and perhaps master if becomes necessary. More on that in another post.

I have the K&L 32-4142 rebuild kit. Pics attached.

I am currently experiencing limited slave return.
I suspect the difference in the piston overall length is blocking the bleed-back port. K&L was very helpful but not able to find the replacement piston.
I will take it apart, (again) and try the seals on the original piston, (when I find it).

(Observation)
When pulling in the clutch repeatedly the slave cylinder is observed extending and returning
The return is not equal.
After a number of pulls the slave is extended to the point where the clutch plates are no longer pressed together.
Rear wheel turns by hand while in gear.

Those 2 pistons are NOT interchangeable. Yes, that is your problem.

I used to be fast....now I just dream about it.

Correct. The piston from the kit will not work. I will try the seals(from the kit) on the original piston.
It is likely the original piston is good and replacing the seals is all that is needed.

Separately, I am looking to determine how to increase the volume of fluid coming out of the MC. Any ideas would be welcome.

The only way to accomplish that would be a new master cylinder..
