Clutch slave leaking again...still...
I rebuilt it once with an aftermarket kit. It leaked. Bought all of the rebuild stuff individually from Honda and re..rebuilt it. Made sure that piston and cylinder were clean..yet again, and it started leaking after less than 30 miles. Appears to be leaking at the lower bolt gasket area. Retorqued the 8mm bolts...cleaned everything up. I did not put any gasket sealant on the gasket. Was that my mistake?

I may be mistaken but, I don't believe the gasket "Seals" anything involving the clutch (brake) fluid. It's simply just an isolator from the engine side case. Is it leaking clutch fluid or engine oil? mine leaked engine oil around the push rod seal after I disturbed it while installing my new Oberon slave. Easy fix, replaced the seal.

Did you check the condition of the slave cylinder bore - ingested grit can scratch the surface so much so that even new seals leak. A bit of fine grade wet&dry can help smooth things out

Yeah the gasket is an isolator. Did you scour the bore? They tend to pit and become unsealable.
I went thru this a lot so got the Oberon aftermarket unit & moved on with my life.
The part just wears out and wont seal. (picture piston in gouged bore). Not worth the many afternoons of wrenching just to see it leak.

If it is indeed brake fluid and not oil, the piston to slave housing seal is likely the issue, or condition of the aluminum slave cylinder wall. If its not scratched, pitted, gouged, id take some careful measurements with an inside mic or telescoping gauge and outside mike to make sure the cylinder is round, no oval and not tapered.
Actually, no that's not true.....if I had a VTR clutch slave that needed work, id remove it and toss it in the garbage can, replacing it with a new Oberon slave cylinder and not spend a minute or dollar rebuilding a stock one
I have an early year non integrated clutch master cylinder with a fresh all service part rebuild, new res cup, SS braided line and the Oberon slave...Very happy with it. Have done the same on two other VTRs for folks, and both very happy with the results over stock.

Thanks everyone...going Oberon..anyone in particular you might recommend I purchase one from?
Found one on ebay, states it's for VTR1000RR and RC51. They claim it doesn't fit a VTR1000F....Really?

This may be an option to buy from https://bluestreakracing.ca/us/shop-...-cylinder.html

You can order direct from them, though Ebay from them, or direct from Oberon.
Ive done one of each now...... really no difference

The Slave unit on the VTR is common across a range of other Hondas - but the one you want is the CLU-3038

Well, I'll be damned...Without consulting with my wife, this is the second time in my life that I have made a mistake. The first was 1969. I rebuilt a VW bug engine. Being a bit of an **** retentive, and know-it-all even then, I made sure all the gaps in the rings were lined up...Now in 2019 I found that when I rebuilt my slave cylinder, I put the piston seal in backwards....Regardless, the Oberon is ordered, it will be installed soon. If you know of anyone who would like a rebuilt Superhawk slave cylinder, yes the piston seal has been <ahem> reorientated. It can be had for shipping from 61822.
I apologize for my mistake, and wasting your time...

My wife says I'm off in the number of mistakes I've made. The 2 I confessed to are more likely a 2... with numerous zeros behind it. You're right dear.

Ordered the Oberon from Blue Streak 1 August. Arrived today, 14 Aug . Installed and, damn...I bled more than necessary as I thought I wasn't getting any clutch! It's really light! Thanks again to all of your help.
