excellent video. Many adjustments can be made to specific rider requirements making the ride safer and easier. I plan to install an air shifter with kill box, due to foot injury. Any advice is greatly appreciated.
i would just like to add a word of caution if i may. you are completely right you can take out your clutch play and it would be as same as having play on it just pulled to the engament zone.. BUT you are thinking of the clutch only a certain rpm only.. see clutch is pretty much like a torq converter it converts % of the engine torq according to its position.. Frictiom zone is the sweet spot where the % of the torq transferred is enough to move the bike... IT IS NOT where the clutch functions.. The clutch transfers torq even if you have it 1 mm moved.. the bike doesnt move because the torq is not enough but be assured that your clutch is slipping if you want to test this.. get out on the highway.. give it maximum gas and just touch the clutch (once taking the play out of it) you will see that it will slip... or when moving from dead stop.. give it constant rpm lets say 3k and try to do it from steep hill.. you will see that the friction zone changed.. what youre doing isnt wrong but the clutch play should be closely monitored.. too much play means it will slip even thou fully pulled in... too little or no play means even the sheer force of wind will cause it to slip
Exactly. There is a mathematical point where the plates are in full spring-force contact with no cable slack. Very hard to find it and unnecessary. Beyond that point there is still no cable slack and the plates begin to slip, and burn It is a bit like there is -20C ice, there is -10C ice, -5C -1C, 0C ice, then 0C water +2C water etc. Same on Fahrenheit scale. Point is: there is full contact with some cable slack, full contact with zero slack, slightly bad to very bad contact, all with zero slack
free play should be about the thickness of a nickle . you should be able to squeeze a nickle in between the lever and the perch where they touch.so really just enough play that you can tell its not on clutch tension . and inch is far too much.
+Salex Not reasonably possible. it will always stay 1-2 cm because of 2 things. 1 The clutch lever will not get longer. If it were, 5-6 cm is no problem. 2 The clutch plates / discs either touch or not. It is a binary system with no options in between. (no transition between the 2 positions, just like number of people in a room - only whole numbers are people, no decimal or fractional or partial people possible. Remains or limbs and heads are not people.)
Hmmm. That`s the same as stating God changes, or God changes mind, or God guesses or gives up on previously made choices which runs contrary to what the church upholds about the immutability of God. Problem for 3 religions right there. Once a carpenter, always a carpenter has a more familiar ring. It`s like once a bike has traction control, it has traction control, regardless if it`s on or not, bike running or not, it has it.

thanks ive always had a hard time understanding how the clutch works but for some reason your explanation is the only one that made sense
Can't take nothing away from this guy hes smart he knows his shit
EXTREMELY clear explanation. Thanks for it.

+Drr.Kivanc 100% agree. Some viewers tested the clutch-slip-by-overadjustment version and observed the same.
+theoverengineer :) glad the science has been worked out. my friends clutch went out at 10k kms he had no clutch play :)
ooooh, clutch replacement is no fun and costly ...

I’m new to my bike. So there is supposed to be play on that clutch ? The free play on my clutch is about an inch. Is that too much free play?
Not if your fingers are 1 inch long. Which can happen, just saying.

Very good explaining!
Great video!
Is there a way to make the engagement zone shorter? My bike has huge engagement zone, around 5-6cm at the ball end.

in freewheeling, is it good or bad for the bike to hold the clucth?
Neither, a mechanical necessity.
so we should shift at the play zone right ?
Clutch engages/disengages the crank from the gearbox. Not the rear wheel.
Great explanation!
thank you for sharing nice information in this video
OR you could have your clutch cable adjusted PROPERLY and just use rev matching.
I have a hydraulic clutch ..... how do I adjust that.
+Bad Juju Same way with its set screw at the lever, if fitted with one.
theoverengineer
I don't seem to have a set screw.. Thanks for the reply.
hydro clutch they self adjust, do to the liquid instead of the cable.
so they don't need adjustments. (short answer)
Is that you, Antonio Banderas? Hehe
noumine Yup. I quit acting and have taken on engineering. It`s more fun ;)
I am the way the truth and the life.
Yes, and if he was a mechanic, he would probably set the clutch the same way. (Carpenters wouldn`t know.)
I was a carpenter once but no longer.

great video
oh.. thinx for correcting me
Physically impossible. Shifting only happens in (grinding gears) or beyond (smooth shift) the friction zone.
Thanks
Guess I better dial in a bit more play ...
Nice
Dont use a clutch squid
clutches fungshiin
Don't use the clutch
That`s another video
:) yeah i know it's cool. this actually helped me a lot as i'm a week away from doing some light rebuilding on my RS
What needs to be done on it?
