Is it possible that the gear grinding that lots of us have,is caused by this cylinder ???
I think it's possible cause if you depress the clutch rapidly if the cylinder take some time to transmit it's power,our clutch will be connected to the flywheel when we will change gear !!! See this !!! :http://www.zr1.net/clutchmaster.html

 

Did you tried a double clutch,i heard that people who do it solve their problem so if it is, that has to do with that cylinder....no ???

 

Anyone ??

Sorry i was talking about pushing the clutch pedal two times before changing gear to be sure that the cylinder do is job correctly !!! Sorry for my bad english

 

If the synchronizers are working properly, they will resist a gear change more if the clutch is binding like that.

I am positive the grind is the result of Honda trying to make the shifter action as light as possible. In doing that they made the transmission more susceptible to the grind problem. I believe the TSB takes care of the problem by installing syncro teeth that have a more aggressive ramp. This also causes a little bit stiffer shifting, magnified by the short throw. The steeper ramp angle of the teeth increases the terminal force needed to overcome the 'syncro engagement' and finish sliding into gear. A quick/ fast shift will overcome the spring pressure much like an impact wrench loosens a bolt. Even the slightest reduction in the speed of your shift should reduce the grind, just as woodwork said. BUT I think the threshold should be just a bit higher, I would take a stiffer shifter any day opposed to the grind.

I will be modifying my syncro sleeves by changing the ramp angles just to see the effects on shifting. Instead of a straight angle, I will be trying a curved ramp, so the initial action will be lighter but take just a bit more effort to engage. The gearbox can also be modified to have less of the 'rifle bolt' feel. The ramps 'backside' is responsible for keeping in gear along with another feature of the teeth. So in other words the ramp profile is what gives the transmission its personality.

PS I also think a hot gearbox aggravates the grind because the springs are a little more flexible at the higher temps? Ohh man now I gotta do another test *heating them and checking deflection*
