Honda VFR hydraulic clutch question

[Scotchmist]

Hi all,

I'm interested in converting to a hydraulic clutch using a Honda VFR slave cylinder like this one.

http://www.ebay.co.uk/itm/HONDA-VFR...628?pt=LH_DefaultDomain_3&hash=item1a01436c9c

Does anyone know the piston bore for the accompanying master cylinder. I've got a couple of options at home and would prefer not to use the stock VFR item.

Thanks.

Alternatively, is anyone successfully running a VFR-based clutch setup? If so, what master cylinder are you using?

Not exactly what you asked for but you can cross check the part numbers to see if they are similar.
I have a VTR 1000 setup,(as the wrecker told me) the master cylinder is 14mm.
With heavy duty clutch springs the lever pull is a little heavier than I would like.
I intend to try a smaller master cylinder.

wallywheels used a vfr750 slave on his turbo woody build and he used a 13mm master cylinder.

Thanks for the replies. I've got a 13mm master cylinder at home so will give that a go. I'll bleed the system and see how much movement I get at the slave cylinder.

I'll pull up the actual ID and post later tonight for you. I've got a Sabre that runs that slave cylinder and can verify that it's a very easy pull with heavy duty clutch springs. I'm at work at present but will pull up my service manual and post here in about 6 hours time.

Thanks, pcoumbe. That'd be great.

Scotchmist, my apology for taking so long to post this. I'm currently in Zambia at work and my internet went down and took until yesterday afternoon to get someone to fix it.

Specs are as follows : Slave cyl service limit : 38.18mm (1.503")
Slave piston svce limit : 38.03mm (1.497")

The standard master cylinder is 14mm.

If you want to reseal it slave kits can be bought on ebay or try V4market.com. They are a good source and good guys to deal with and only sell quality parts.

Hope this helps,
Regards,
Pete
