heavy clutch
By: marcbeez Date: January 8, 2017, 2:08 am
---------------------------------------------------------
hello, i've just bought a NF civile '74, 19000km not restored
just well maintained.
the gearbox is somewhat difficult but the main problem is the
very heavy clutch. I have 8bikes morini 250/350 bmw r27/r100s
mz150 '71bonneville but none of the clutches are that heavy. My
forearm is very sore at the moment . I installed a new cable ,
same same, please help, or do I need to go to the gym!
greetings from Antwerp

The clutch should be light to use. Either the cable is
incorrectly routed and is binding, or you need to do some
investigation inside the case.

I agree with Nick,
however,
Yes, you have to do ... muscle. At first it seems hard
(And probably is), then you get used. ;D

I agree with Nick and Randell, you will get used on it. But
there are differences between the bikes. I have three NF and the
resistance was not the same on each bike. I found out that the
lever were bent differently so I bent them more straight that
the ball at the end of the lever reaches the handlebar when it
is pulled. Now I can reach the lever more outside, the lever arm
is bigger and I need less force.
Sometimes washers were added to the clutch springs to get more
friction when it slipped, this could be too.
good luck
Kater

thanks for the swift reply, what is the correct routing for the
clutch cable and how long is it supposed to be. On pictures some
cables entre between the 2 clocks on the dashboard and some go
directly down next to left downtube of the frame.
On the net I found that halving the weight of the flywheel can
do wonders shifting?
I have been riding bikes for 41years now and my falcone has the
most difficult gearbox I ever encountered. This includes some
belgian sidevalve 500cc jobs from the early 50's.
The steering and comfort are wonderful , and with the frequent
speedtraps in belgium( flemish part) its speed is more than
enough.
greetings

Given, that you have to get the hand (... or rather the foot)
;D
and that the gear shifting is perhaps the most difficult part to
learn on the NF, ::)
if the transmission is in order and the clutch as well, the
gears must engage well and quickly, both in accelleration and
decreasing. 8)
In any case, the gearbox is "precise" and just a decline of
attention, distraction or fatigue on the part of the pilot is
cause of malfunction. ???
To shifting well, the gears should NOT be "pulled" ;) (when you
want to shift gear, close the throttle , count till ten and than
shift the gear)

you've found out the gearchange on the falcone is a bit crude,
they are all like that.
just take your time , just like driving a car with a non
synchronised gearbox.
i can actually double clutch mine, by using the neutral between
the gears :-)
you might want to have a look at the clutch , sounds like
somebody added spacers , or stronger clutch springs.
the clutch shouldn't be harder to operate than your morini.
if you in there check the clutch basket, the basket tends to get
nothed by the plates,
if it is the clutch doesn't disengage properly, making the
gearchange even harder.

thanks Newbie,
i've been double clutching on the downshift, works fine. I
replaced and rerouted the clutch cable with a new one and oiled
it with teflon oil , works better. waiting now for a kit of
nylon coated cables . I'll check the clutch to see if everything
is standard.
cheers

The clutch cable operates a shaft set into the timing cover.
It's not well lubricated, and can seize. Relatively easy job to
remove the timing cover, making sure NOT to dislodge the timing
gears. The shaft can then be removed, cleaned and lubricated.
I've not had mine off, but I did buy a spare timing cover with a
very stiff clutch shaft that responded well to a strip and
clean.
