Clutch slippage.

[Kyle844]

Hey guys, been out riding my bike lately which i recently got but one pet peeve is the clutch is either ON or OFF. It's really hard to slip it to take off whether i rev the Sh*t out of it like a 2stroke or not. there is little room between the clutch is engaged and when it disengages. Is there a way to add more "slippage" to make the bike easier to take off so i don't feel like a loser always poppin the clutch or killing it. I have no information if this clutch is new or not, shifting works great and smooth also.

Have you checked the clutch cable?

Point in case being that they´re exposed to the elements and more often then not rust when unattended.
Easy enough to check.

Yours is a streetfighter correct?(Ie;lacks all the plastics)

In that case just unbolt the gearlever at the engine.
Takes a 10mm metric.It´sa through bolt at the gearlever axle.

Then unbolt the 5pcs of M6 allen screws that hold the cover for the front sprocket,and indeed the mechanism for the clutch.
This is done with a 5mm metric allen.

Depress the plunger for the clutch mechanism and unhook the wire from the bracket.

Depress the clutch lever at the handlebar.
Now pull on the end of the cable that is for the mechanism end to make the wire return.
It should come along freely.
If it does not...time for a new clutch cable.
When fresh this can be done by hand.If you need to wring out a pair of pliers to perform this the wire is shot.

When the FZR clutch system is up to snuff it´s rather soft to operate IMO.
Smooth and soft,and if anything i guess it could do with a set of harder clutch springs actually.

K,
that is the first time I have heard someone complain that the FZR clutch actually works without slipping.

Racer is spot on about testing the condition of the actual cable. If you have to lube the cable you can make a little funnel at the top with Kids plastercine (modeling clay / play dough ) a little puddle of WD 40 or chain lube at the top, keep the pool at the top full until you see it drop out the bottom of the cable on to a clean set of kitchen paper towels ( to keep it off the floor & sooner or later your tyres.)

Alright I'll have to go out and check the cable! pulling the clutch lever is really smooth and feels no binding or anything but i'll check the wire itself and go ahead and lube it also.

If the cable checks out...

According to the manual the clutch discs should be a minimum of 2.8mm thick.
As for free length of springs i´ll have to check.
The ones in mine are colour coded red at least.

Torq for the screws that hold the clutch springs is 0.6kgm.


That the lever feels smooth is no guarantee.
Mine was exactly the same,but due to the leverage of the clutch lever a grown man has no issues what so ever to depress a cable that´s in REALLY bad condition.
When i dismantled mine i had a hard time making it move even with a pair of sturdy pliers at hand.
It was however still easy to operate with the lever.

Difference in feel after replacing the clutch wire is like night n day TBH.
All of a sudden you get the feel for what,where and when the clutch actually does something.

Mine still slips on occasion.
Ergo,what i have in mind is to tear the clutch apart again-which is fairly easy mind you-to dress and deburr the drive cage and hub that the clutch resides within.
As i run a raceshop i also happen to have this big*ss hot tank standing around,so i thought i´d toss the clutch discs in there to "wash" them with the alkalii in there.
Point being that i have no clue what so ever if some PO has filled common oil into the bike-sans the friction modifiers needed for bike use.

My clutch discs measure in at 3.1mm and the MoFo still slips...so something needs to be done.
This slippage comes n goes..
