Clutch dragging?

If the inside of the gear selector case is anything to go by the rest of the inards need a good clean ;)

gear selector case is an oil dead spot and it often catches fines and stale oil that settle into a residue beside the lower bolt boss, rest of your engine will be fine

Good to know Red. Thanks
 
Well not on my bike,its very easy. I do have a set of Reds Kevlar Clutch plates. Had a horror time getting all the gears,spent ages adjusting the eccentric but it was not getting enough throw in the hook gadget in the selector. I do get a few more false neutrals on a big day if I get lazy, I think the early models tend to this more that the later ones. So how about a show of hands as to how hard neutral is to get when stopped.
 
Actually pretty easy now that Red and Mark have had their magic fingers on my eccentric  8). Also got a Redax kevlar clutch.

At at stop intersection rather then holding the clutch in while in gear, I usually just reach down and flick the selector lever with my HAND to find neutral. All the way down and 1/2 a click up - No big deal. Besides it looks cool ;o)

And don't forget to ground the starter solenoid through the the neutral switch as it saves exploding starters if you ever accidentally hit the starter button while cruising - Meaning you can only engage the starter while in neutral.
.
With all their abnormalities, Breganzies have a great transmission. If necessary you don't even have to feather the clutch, all one has to is bang it into a gear.

I don't believe over the years on this forum where I recall a member posting about a transmission failure.

Now your talking  :o

Clutch drag only an issue on the 3C as the DPO had fitted one of those easy clutch conversions and butchered the cover on the process.. lucky for me have sourced another unmolested cover from a bike built on the same production run... how near original will that be  :o
 
I've owned this bike ithe first time 1991 and it was still a bitch to get into neutral, although 25 years It's hard to remmeber. It's been through a pretty significant rebuild from Redax as well which I believe involved the gearbox. When I bought it back the gearbox was unusable, beyond heavy and frankly a $1000 for a hydraulic is on the wishlist but the DAM conversion was quick and cheaper by some way.

By the way, it doesn't butcher the case, it uses the inspection cover.
 
. in my experience the biggest issue with Laverda cable clutches is that the perch wears due to lack of long term maintenance which then causes less than complete available travel to affect full disengagement. As for heaviness well to be honest two of my Hydraulic clutch Laverda's are heavier than the non modded clutch on the Jota. Guess I have a Laverda wrist ( non limp )

Looks butchered to me

Two types of clutch extension levers. The early version required a slot to be cut out of the upper surface of the cover ( as per Brett's photo), the later version made by DAM is fitted through the inspection cover. Both are damn ugly, no pun intended.
 
One thing I must comment on is be careful torquing them 20mm bolts to hold the clutch pac on them thin stanchions - Not more then the specifications (What is it 10' Lbs - Whatever very light) and use Blue Loctite because if you strip one there's very little metal left to fix it.

It can be done neatly... or, as is usually the case, not so neatly!

I set the sprocket cover on the mill to make a nicely machined slot for the lengthened levers.  If the lever is fitted with a new pin and cable bracket, it doesn't look too out of place.  Things get truely ugly if the re-used cable bracket has previously been mangled by a too loose chain.

The angle of approach of the cable to the lever also has a big influence on how the clutch works.  Get it right, the clutch will be a delight to use, get it wrong, more problems will arise.

If you lower the cable holder bracket so the cable runs in a more horizontal plane, you will get a little more lever travel, simple geometry.  Might make just that little bit of difference.

Just fitting a longer lever is not all there is to it...

Will have a look, thanks for the tip.
 
If you are going to have something that ugly hanging out the side of your bike you may as well have had something useful and got the one with the bottle opener built in  :LOL:
 
My clutch cable hangs precariously out the left side but protected by a Dunstal fairing  ;o)

She's a ONE FINGER twitch with my left hand and if you can't twitch, just BANG It. I've said before - Never seen a Berganzie Forum Member complain about a broken transmission.

Ron, I'm here to complain about a broken transmission. In the 77,000 km that my Jota has covered in its life, the crankcase has been apart twice to fix gearbox failures.  Crankshaft, rods, pistons, etc. are all still doing OK. It's the transmission that broke - twice. The first failure was a broken 4th gear (fixed by previous owner) and the second failure was the sleeve gear bearing (fixed by me).
 
I've seen several busted Breganze gearboxes.  Usually worn or snapped mainshafts, sometimes worn gears.  Replacing all bushes and bearings when rebuild time comes around is standard procedure.  Gears often go bang due to excessive bush wear.  Shafts and sleeve 5th gears are shagged through ignorance of over-tensioned drive chains.
