Curious if anyone else experiences a grabby clutch when first starting out on a cool fz/mt10. With the fz, when taking off from a stop, you need to ride the clutch a bit. But whenever the engine is cool, the clutch will grab, sometimes stalling the bike since you really need to slip the clutch when taking off from a stop. Once you've taking off a couple times the clutch seems fine. The bike has 8,500 pretty easy miles on it, and I run mobile 1 20-50 v-twin oil which is made for wet clutches. But it's a bit annoying and concerning having a clutch that grabs when bring used the first couple of takeoffs.

Yep i have noticed that, i have to manoeuvre back and forth to get my bike out, and have found that when i start the engine if i pull the clutch in a pumping motion at least five or six times it makes the clutch work as it should.

Most wet clutch bikes have a bit of that when cold. That's why the rear tire moves when on a center stand or rear stand with the clutch held in for a while. 20 is a fairly heavy oil for cold temp, so it takes a minute to loosen/thin up.

Had that prob with the break in oil, once I put Castrol power 1 10w50 in, that went away, idled better and revved way better. I'll never run anything else.

Yes, same here. I guess this makes it "normal".
I’ve noticed that the clutch acts somewhat inconsistently as I let it out for the first time each day, when I take off from my driveway. Sometimes it’s a little "grabby" and sometimes it’s not. It’s only that very first time, though. By the time I get down to the stop sign at the end of my street, the clutch is perfectly smooth the rest of the day. I imagine my clutch plates taking their first bath in the motor oil each morning, and had decided that the clutch simply needs to be disengaged/engaged that first time each day in order to properly bathe those plates in the oil. So, I’ve just learned to be a little more sensitive to it when taking off in the driveway first thing in the morning.
I also run 20w-50 (full synthetic), as I am in Phoenix AZ (I believe you are as well). All my research in the past has caused me to go with the heavier viscosity due to the extreme heat in this region.

Yes, I live in Phoenix Az as well. Like you said, it's usually just the first time or two taking off after first starting the bike. Although this is my 35th motorcycle and I have never experienced this kind of behavior before. I've stalled it a few times considering this bikes need a little slipping when taking off and when it grabs instead of slipping. A little frustrating because it's usually when you are trying to time the space between cars to pull out. But once you've ridden a mile or so, all the other takeoffs are pretty normal.

I have the same problem, after I start the bike my usual practice now is i pull the clutch in and release it about a dozen times in neutral before I put it in gear and leave my driveway, find this lubricates the clutch plates which is where the grab (*friction) is coming from. Might seem weird but it works and it's just one of the idiosyncrasies of the bike.

Actually glad I found this thread as I have been having the same thing and thought it was just me or my bike. It’s a right pain, as I find it stalls at the worst moment, generally just after leaving work and stuck between cars after filtering as far as I can until the gap gets too narrow.
Then when it stalls it must slightly flood the engine as it’s hard to start after a stall, but it will start on the button, instantly if I turn it off properly via key or kill switch. Worst time to stall and have a hard starting bike is when sitting between 2 lanes of traffic as the lights change to green.
My bike only has 1500 miles on it, bought it with 750 miles on it, (ex demo), so might be me still getting used to it as I am stalling it less than I used to when I first got it, but damn, I haven’t stalled any bike since passing my driving test several years ago and now this bike seems so easy to stall for the first 1-2 miles until everything is warmed up.
At least I can see it’s not just a problem with me or my bike and seems to be one of those traits of the bike. I guess it is effectively a race (R1) engine and not inherently designed to deal with stop/start traffic.

I wonder if changing to a different brand of oil would help?

If you're not tracking your bikes, there's no need for the heavy stuff. Try 10/40 and it should go back to normal. I live in hot TX too, and such heavy oil only creates more friction and heat if you don't really beat up on the motor. I'm actively looking for a black ('17) FZ-10, since they were not made in 2018. Hope to find one at a good price soon. Most I've found want '18 (or more) money for them. Crazy.

I wonder if changing to a different brand of oil would help? The bike had its first service at the dealer prior to me picking it up. So it will have whatever they used in it. I suspect a 10w/40 fully synthetic YamaLube. My track bike (2004 GSX-R 600) uses Castrol Power1 Racing (fully synthetic) 10w/40 and when the MT-10 is due it’s next service early next year I will be replacing the current oil with the same Castrol oil I use in the GSX-R. Hopefully the clutch will be better after that. Happened again today. Literally pulled out of my work, travelled 1/4 mile to the traffic lights, stopped and waited. When they changed I put it into 1st and as I went to pull away the damn thing stalled again. This time it was really hard to start up again. Just did not want to. Got it going and was fine after that. The worst part is the hard starting after a stall when cold. It must be slightly flooding the engine when stalling as I have checked and I can turn it on then off and back on again with the key / kill switch. It will literally fire up instantly on the button every time, only ever dislikes restarting if it’s been stalled, more so when stalled on a cold engine.

I've been using Motul with no issues, I have to admit that Suzuki shifting and clutch smoothness is far superior to the FZ10. My last 2 bikes were Gixxers and they have almost telepathic shifting compared to the Yamaha crashbox that I have now, I'm used to it now but it took me some time plus now I have a quickshifter to play with.

I've only owned 2 Suzukis, a Hayabusa and SV-1000 (naked), and both had a super smooth (and quiet) tranny, and great clutch as well, although both were hydraulically actuated. This FZ-10 (I want a black one, hence FZ) would be my first ever cable-actuated clutch. Hope I don't regret it. Ha ha. But there shouldn't be much difference between cable and hydraulic IMO. It's all about everything else, I guess. I don't mind having to start with a bit more clutch, but if it's inconsistent, then I can see the frustrations with that. Problem with these kinds of bikes is for some reason, 1st is super tall, and the other gears super close. That's fine on a race bike, or even a track-oriented one, but on a naked? Utterly stupid. How difficult would be to regear them properly, if they're regeared anyway? Oh well. If I ever find one, will make sure to at least test-ride it shortly to make sure there's nothing really wrong with it. And to make sure the side-stand recall is done, since I wouldn't want to get stranded in the middle of nowhere with the stupid bike thinking my side-stand is deployed when it's not. Have a great week gang.

I've had a myriad of Yamahas and I find the -10's clutch action super nice. Light pull, progressive engagement, easy to find neutral, best tranny feel of all the Yamaha's I've owned. I start the bike up in my driveway, warm it up 30 seconds then have a short 1000 ft distance to the gates where I have to stop and wait for them to open, than another 500 ft to the stoplight, then I'm off to the races where I won't have to stop for at least 20 miles but have not noticed any grabbiness at all when cold. Perhaps your clutch cables need a bit of adjustment. I do find the clutch engagement to be fairly quick as you let out the clutch, but I prefer that. If you are used to a more leisurely clutch engagement I could see how you might be prone to stalling the engine. I like the -10's action, I'd call it precise, it wants to get on with the program.

If you are used to a more leisurely clutch engagement I could see how you might be prone to stalling the engine. I like the -10's action, I'd call it precise, it wants to get on with the program. I think that sums it up well, the clutch engagement is very quick. I have noticed that when releasing the clutch it is a case of "nothing, nothing, nothing....oh now it's nearly at full engagement" I find that it's the last 1-inch of travel on the clutch lever has all the engagement. Clutch adjustment has been checked and it 100% as per the Yamaha service manual. The GSX-R on the other hand is far more progressive or "leisurely" as you put it. I think that's the issue. A very "snappy" or "quick" clutch coupled with a cold engine + rider who is used to progressive clutches from other bikes = prone to stalling when cold. I have never, ever stalled it when warmed up though. Think the cold engine and rich fuel mixture which generally goes with a cold fuel map makes it just that bit easier to stall. Think I just need to get used to giving it more revs and slipping the clutch a tad more when cold is all. Not to mention it is my first time back on a road bike in 4 years! All I have done for those years is ride on track, so the only time I pull away from a standstill is when leaving pit lane which is not quite the same as stop-start traffic.

I'm used to fast-grabbing clutches, and that's the way I like them, so seems the FZ-10 would be a good partner there. Made one last ditch effort to get the only local black FZ but doubt it'll get anywhere. Was expecting an answer today, but didn't hear from them. Hopefully tomorrow, to move on if needed.

So I'm wondering if the issue I'm having is the same or not? My bike starts well even in cold (i.e. 35F); usually use 10w40 synthetic oil (napa, amsoil or yamalube). I have no trouble leaving from a stop (doesn't stall), but if I have to pull the clutch in during the first ~ 1-5 minutes of riding, the bike stalls. For example when I'm getting ready to stop at a stop sign. I end up having to restart the bike while coasting towards the stop. No issues starting at that point, and no issues leaving the stop again. And it only does it during that short period of time after leaving; unfortunately there is a stop sign at the perfect distance from work.. I'm starting to get used to it but still, not very safe for the bike to just stall while riding. Any thoughts? I'm planning on replacing the spark plugs tomorrow as well as doing a throttle body sync. Haven't done either since 8000 miles and at 25k currently.. Going to replace the air filter as well once it comes in.
