Yes, I know that master cylinders are serviceable. This is a point that I'm going to work on when I'll take the bike to the Suzuki mechanics again.The way you describe the clutch action, it kind of sounds like either the master or slave is not holding pressure. When/if you get in there, see if the o-rings are replaceable. It's like when the brake master cylinder on a auto is going bad, they start leaking fluid around the cylinder and the brakes won't stay as firmly engaged. Same for the slave cylinder or brake caliper on a car.
And did they happen to say why the 2007 clutch worked but the 2019 didn't? Odd that if the newer one was installed with all the correct parts that it would work less well than the older one.
I tend to disagree on this point.The hydraulic clutch v/s cable has nothing at all to do with your clutch slipping if either are adjusted correctly.
This could be a good test to do to evaluate the slave cylinder's operation. Nevertheless I'd like to point out that although the clutch lever pull becomes softer upon not using it for a while (like on a long straight road without traffic) and then suddenly regains all the pull effort after reusing it to change gear, this happens only with the engine running and not at all with engine off (when the lever pull is always constant).Easy enough to verify, just remove your lower engine cover, pull your clutch lever and see that the arm moves to disengage the clutch. Hold the clutch lever in for a minute or two and see if the spring return on the arm allows the arm to move back toward the clutch engaged positon......if it does not then the hydraulic cylinders are not leaking by.
But even if the seal in the MC was leaking it would prevent the clutch from disengaging....not prevent it from fully engaging causing the clutch stack to slip as the OP is reporting.
Excuse me sir, I think that you are a bit too self-confident ...The fact that they keep telling you the hydraulic clutch may be issue on the newer style clutch stack v/s the older style clutch stack is enough to tell me you should find another mechanic.
If they have never worked on a M109R before then they likely have the adjustment too tight and your fix may as easy as slacking the slave cylinder adjustment a bit.
Adjusting the clutch play too tight is pretty common for anyone who has not worked a M109R.
Uh ... your life? The comedy of your life? Then let it be, I will buy you a ton of popcorn so that you can relax in you armchair to watch your comedy.I've said too much , I'll just sit back and watch the comedy.
You know ... it's that "100% for sure" that I greatly dislike. Who are you, a magician with the glass ball?All I can do is point you in the right direction...... hydraulic or cable makes no difference if both are working and adjusted properly......this is 100% for sure with no exception. BCS
The world may be a bit more complex then what we like to think.All either one is doing is moving the arm, if either is adjusted properly and allowing the arm to return fully under spring pressure then that's all there is to that portion.
If the arm is returning fully, then explain to me how the hydraulic clutch could be a factor?
If the arm is not returning fully then its most likely going to be an adjustment issue, just as I said.
I'm sure that Suzuki engineers had their reasons when they designed the 2nd generation clutch kit, but I'm also pretty sure that when they did it they thought only about the stock clutch cable, not also about an alternative hydro clutch kit designed by someone here on the board (although I think it was a very good idea - thanks Rainey again for this) and using a Suzuki C90 model bike's master cylinder.You may indeed want to switch back to the beefier springs from the 2007 pressure plate but that has nothing to do with the hydraulic clutch portion.
My endeavor has already reached a good step in the resolution of my problem, because I had installed a 1st generation clutch kit and this removed all clutch slippage even with my hydro clutch setup that possibly is starting to deteriorate.I have led you to the water hole, its up to you to lean over and get a drink.
Good luck in your endeavor.
Well bud, not sure what to tell you then.You know ... it's that "100% for sure" that I greatly dislike. Who are you, a magician with the glass ball?
I admit that I appreciate your effort here on the board to help people, but when you say 100% sure you should also show evidence of this.
I started with the 1st generation clutch kit with stock cable, next moved to hydro clutch in 2013 (old design), next changed to 2nd generation clutch kit and therefore I can comment on my personal experience about the relationship between these 3 elements. What yours??
.... if the 2nd generation clutch kit is a modification of the 1st one, while it's still possible to order both of them from Suzuki??My endeavor has already reached a good step in the resolution of my problem, because I had installed a 1st generation clutch kit and this removed all clutch slippage even with my hydro clutch setup that possibly is starting to deteriorate.
Of note, I did that especially because the clutch discs that I had before (2nd generation) were nearly destroyed (they found a big deposit of cork in my clutch basket and some of the metal disks were discolored in blue, a sign that the metal was cooked up to probably 300 - 400 °C). Si I did not have other choice.
Your self-confidence could be good to have, but I prefer to drink not only from that water hole that you indicated to me. I was supported by a team of professional mechanics working here --> https://www.miazzon.com/
I apologize for the Italian, but I tell you that they're well respected in their field, even if my '9 is the first one that they've worked on. So persisting to say that they do not know what they do is ridiculous.
Another question to you ... if the 2nd generation clutch kit is a modification of the 1st one, while it's still possible to order both of them from Suzuki??
Sometimes you remind me of a Facebook influencer ...
Also, and my apologies for being a cynic, why would Suzuki stop selling parts that they have in stock? My guess is that once the old parts have been sold and stock has been depleted, they will list superceded part numbers..... if the 2nd generation clutch kit is a modification of the 1st one, while it's still possible to order both of them from Suzuki??
As far as I know,
Suzuki never admited that 1st generation clutch is not good, they simply designed new one for the 2010 and up bikes. If you order clutch parts for the earlier years bikes, you get the 1st gen. clutch parts, and if you order clutch parts for 2010 and up, you get 2nd gen. parts. Rainey found out that they are interchangeable, and many of us did interchange them... Again, Suzuki did not say anywhere the clutches are interchangeable....
