Title: v50 clutch question
Post by: lucian on August 04, 2019, 07:43:52 PM
  My daughters has been improving her road riding skills on a gz250 we up for her this season.  She did her first out of town ride with some highway involvement today and did a great job overall. She is getting to the point she would like to get back  on her v50 and she rode it some today but found the clutch pull annoyingly stiff. The clutch works as it should and I have lubed the pivots and cable .She has small hands and compared to the little Suzuki, it is a workout.
 So my question is , is there a way to lighten the clutch pull? Are there lighter clutch springs available ? Or perhaps a way to convert it to hydraulic  master and slave?

 TIA, dave

That bike does have a stiff pull on the clutch. I do not know of a bolt on hydraulic solution although MG Cycle sells a slave that fits big block 5 speeds.
The easiest and cheapest solution would be to find a lever assy that gives more leverage making it easier to pull. There is probably a Guzzi part that will work but I am not personally aware of that.
Hopefully someone will chime in soon with that info. It may be that someone at MG Cycle or Harpers can point you in the right direction.

I have not used these but know they exist as universal application:

Works by applying a pulley mechanical advantage.

The Guzzi clutch will never be as light as that GZ250.
Go back to the clutch cable.  Inspect the routing.  Make sure all of the curves are as wide and as gentle as possible.  Tight bends make a huge difference in pull feel.
You don't want the replace the clutch springs.  The task starts by unbolting everything that is not the motor.
Maybe a longer lever could be fitted?  But that would also mean more travel and a wider grip for small  hands.

Time for a new cable.

With a little ingenuity, this system could probably be adapted to a V50, making clutch actuation much easier.  A nice feature of the Magura system is that it uses mineral oil rather than (paint damaging) brake fluid. 

MG Cycle also sells a clutch slave cylinder which could likely be adapted to a V50 as well, and combined with a Brembo clutch MC.

I have never seen a hydraulic clutch system fitted to a smallblock (the clutch has an easier pull than any big block), but I see no reason why a hydraulic system could not be fitted to a V50.  Installing the slave cylinder might take a bit of creativity, but I'm sure it could be done.

Not sure a hydraulic slave cylinder will fit in the space on top of the transmission, under the battery tray.

Perhaps a low friction cable (such as Venhill) and a dog-leg lever would help?

There is only one clutch spring in a V50, a diaphragm type. #1 here.

I reckon it would, Charlie
The lump (piston side) of slave goes where outer cable stop is, not under tray but on top of gearbox
The bb kit would need rod extending I think but other than that, should be doable
Trick is getting right size m/cylinder, all bb conversions I’ve seen aren’t actually lighter than good cable set up
Far easier do as you suggest first, good cable, proper adjust and dog leg. I used v7 perch and lever, maybe Lucian’s daughter should have a go at new v7 clutch pull, that’s easily attainable for little $.
If that’s too hard, then hydraulic with care on m/c size

Thank you gentlemen, I appreciate all the replies.  Looks like we have some options to consider which is great.  The Magura  option looks very interesting. Not sure which way  to go but will definitely post up whatever we try.  Perhaps I will get a modern cable first and see if that makes enough of a difference for her.  Thank's Charlie for the diagram , and to all for the suggestions. :thumb:

A dog-leg lever?  Don't know if one is available, but their shape allows the same cable pull with a closer starting distance - stronger part of the grip & good for small hands.  I had to switch brake levers on the Monza and the new dog-leg is an easier pull.

I'd love to find a matching dog-leg lever for the clutch, so if you find one, let us know.   :thumb:

Also check the balance between the cable adjustment and the lever adjustment on the back of the gearbox.  It might be possible give a lighter feel.

Sorry to revive an old thread, but I'm interested in whether or not any effective solutions were found.  My wife finds that her hand gets tired/sore after riding her V7 III all day, and I'd really like to find a way to reduce the clutch effort.  She's also got a lowered V85, and loves the clutch on that, but she really feels that the V7 is the right bike for her from a size/layout perspective.

Any suggestions would be appreciated.

Cheers,
Shaun

apparently the V85TT clutch fits , and results in a two finger clutch
didnt try myself, but a friend did the conversion on his V7
