Hydraulic clutch

Seems to be trying to fix something that is'nt broken, again! So many of these "Upgrades" seem to be utilising modern technology for the sake of it, rather than out of a real requirement.
That, of course, is just my view. Would'nt life be dull if we all liked the same things.

Bob.

Is the cam drive going to be bolt on? And stupid question, is the cam running backwards and does that actually matter?
With people reporting two-finger or so action with a properly set up stock clutch, what's the advantage of hydraulic, aside from the usual cool factor?

Yes the cam gears will be an easy bolt on.
With a fresh properly lubed cable and a good stack height you can have a two finger clutch. With the hydraulic setup you will always have a two finger clutch. The clutch dissengagement is cleaner because of slightly increased thow so it's easier to find neutral and engagement is smoother because of linear travel of the clutch piston. The stock clutch ramp is very steep in the center of it's travel which means the clutch bites hard with a small amount of lever movement. The hydralic clutch kit makes a Norton clutch feel similar to a modrn bike clutch.

Ah, yes, I needed to draw circles with my fingers to figure that out. That should greatly improve timing. Would there even be an advantage going to a crank trigger ignition?

As always, very nice job.
Will it be able to set up the clutch poorly and not know because the hydraulic over compensate? Just speculating here.

I have fitted one of Jim's hydraulic clutches and 'am very impressed with the consistent, light, linear pull. The system looks like it will out live countless cables and wasn't that much more difficult to install than a new cable. Bleeding the unit takes a bit of patience and is best done overnight, as the unit will self bleed; I got mine so that I could ride the machine after fitment, but the engagement, initially, was right off the grip, the next day it was almost mid way and the day after that somwhere near 2/3-3/4 where it has remained. The hudraulic actuation doesn't care where the bars are positioned and doesn't need lubrication; the best cable clutches I have had bearly lasted two months before losing significant ease of movement; clutch cables are also water condiuts for filling the transmission.
To be fair: you can purchase an aweful lot of cables for the price of the hydraulic clutch, and at a concours-de-elegance you'll get you head handed to you the moment they see the hydraulic clutch; this is not an item for purists.

Jim — I'd like to add my praise for your timing gears and your hydraulic clutch actuator. It's great to see some well-engineered innovation. If the Norton factory had kept going, these are the sort of modifications that they probably would have considered. I often wondered why Norton didn't go that extra yard and instead kept the chain. Keep up the good work and I hope sales go well.
