Drive line "shudder" on acceleration.

[semperfidher]

I'm an s10 noob! That said, my bike has a super annoying footpeg vibration on acceleration between 3-4k RPM . I noticed it right away on the test ride and made the shop's mechanic assess it before I'd be willing to purchase it. Anyways, he explained it as a drive line/shaft drive nuance, and since then I've seen a very good explanation online about what causes the shudder (can't seem to find it now). Anyways, the logic behind the vibration makes sense (loading and unloading the u-joints(?)), but I'm bringing it up because it seems like no one online is talking about it. I assume the lack of discussion is for one of two reasons:
1. Because it truly is normal for the bike, and everyone just ignores it because we all have the same sensation, or
2. Because no one has that sensation, and there's actually something wrong with my bike and mine alone.

I guess I just would like some input/reassurance from the community as to whether or not I'm in the clear to just enjoy my new moto.

What year bike?

 

[semperfidher]

It's a new '13. 75miles on the odo.

Re: Drive line "shudder" on acceleration.

I put 68,808 miles on my 2012 Temere and now have over 14,000 on my 2014ES and have never experienced this.
My $.02 worth. I think I would not be liking this. As far as loading and unloading of drive shaft parts... It sounds to me this happened while you were under acceleration therefore no unloading just loaded????

 

[trikepilot]

maybe the infamous clutch vibration at 3-3.2k RPM that is all the talk these days?

Clutch basket vibe made this vibe on my 1012 until I changed it to the 14 basket.

I have a 2012 and it had the same problem. It's probably the clutch basket. You can test this. When the vibes are evident pull gently on the clutch lever, not hard enough to disengage the clutch. If the vibes go away then you have identified the clutch basket as the culprit.

If it is the clutch basket you can install a 2014 clutch basket for a really worthwhile fix.

Oh hell guys I think he said this was a NEW bike with like 75 miles on it! Does the clutch basket problem come that soon?

The clutch basket "characteristic" normally is there from the beginning. I noticed this on my ride from the dealership with my new 2012. It is interesting that your 12 didn't have it, Brick, as I have ridden several 12's and 13's and they all had it. The first thing I noticed on my 14 is that it was absent. I recall our earlier discussions on this forum back in the beginning and we all thought it was just the character of this 270 degree twin. Later we had an explanation from sharealike, who developed the fix for the V Strom clutch "chudder", along with pics of our baskets and why they had this. He developed a mod to take most of it out, but those that had that done say it was better, but not as good as the 14 basket. I just got used to it and ignored it, but really enjoy the absence of that on my 14.

Get a 2014 basket...... and maybe a CCT........

 

[Ramseybella]

I just got my CCT in the mail yesterday my chain is chattering at 25k !!
My mechanic wanted to install a manual CCT but Yamaha won't cover any top end issues under YES it they come up without an OEM part installed.

Thanks for all the input! Yeah I really don't like the feeling at all. I'm pretty sensitive to anything mechanically wrong with my cars and bikes, and even though I didn't know anything about the S10 yet I was sure it wasn't normal. Has Yamaha rogered up to any of these complaints by acknowledging the issue under warranty? (I have literally only ridden the bike once and changed the oil). Unfortunately, I'm out of town for an exercise until later this month, so I won't be able to test out the clutch isolation method til then.

Curious, has anyone who used to have/still has this issue had any problems or mechanical damage as a result? Or is it just an annoyance? Quite frankly, I don't really feel like dumping a couple hundred bucks on engine parts for a bike I just purchased. This bike replaced a KLR, which has its fair share of "quirks"... Was hoping to steer a way from that by going with the Yami

Then you will have to live with it..
This may sound stupid honestly your going to dump money on toys for it what is a couple hundred bucks then the vibe will be gone forever?
No Yamaha has not sent out any notice on changing clutch baskets I think the Price SNAFU was they're attempt to fix it without admitting it was faulty by 2013 who knows? :

 

[limey]

It's a new '13. 75miles on the odo.

It's needs to be broken in, give it about 3-5,000 miles and it will feel totally different .

 

[offcamber]

I get drive line slap when the engine and wheel speed are close. Only happens when moving slow like in a parking lot and not all the time...I haven't notices the 3200 vib...

 

[markjenn]

I'd certainly investigate replacing the clutch basket which may (or may not) help, but some of what you're talking about is simply a big twin shouldering a heavy load at low RPM. There's really no reason to be giving the bike full throttle at 3K..... no big twin likes this very much. To my senses, this is lugging the engine. The solution may be as simple as using a lower gear.

If you just bought the bike, I would tell your dealer that between the 12/13 and 14 model years, yamaha updated the basket to a different part number and it is rubber damped. If they have a 14 model year, see if you can ride. That's the way it should be. The new baskets fit the older bikes and your gonna love it. If you're hard pressed for the couple of hundred it will cost you, then have them call the yamaha rep. I would push the issue if you know there's a fix and the basket "is" the fix. They may not want to put a 14 basket in an older model year bike just because it wasn't built with it originally, but maybe they'll discount a new basket for you and inapstall it under warranty.

I also just bought a 2013 (in April 2014 and it has 10,000 miles) that is smooth in this rpm range. It does have a light vibration in the handlebars between 4500 and 5500 rpm. A lot of members here are springing for new 2014 clutch baskets that have rubber dampers and new cam chain tensioners. I tend to wait and fix things when they are actually broken or showing signs of imminent failure. I rode a 2007 Vstrom with much more noticeable vibration in the clutch under heavy engine torque situations and the Suzuki was still running just fine 100,000 miles later.

When my clutch annoys me, I will replace it and the friction plates. When/if my cam chain tensioner starts to rattle, I will fix that too.

The jury is out on which changes to the new tenere are actually for the better. Rubber dampers loose their elasticity with time. The CCT is a redesigned part in 2014....maybe better, maybe the same, maybe worse...who knows.

I have been in the motowrenching world for years and have seen steps backwards and forwards with design. The new tenere has weaker valve springs and lower tension piston rings....hmm, not good in this engineers mind.

No, I believe I will ride mine for a while before I start yanking parts that have not failed.

Just one mans opinion. However, I do plan on purchasing YES warranty just before my bikes first birthday, it is too cheap to pass up. ::021:: and fix stuff when it needs it.

Someone has tried this already and it doesn't fly. Yamaha doesn't consider the 12/13 basket to be defective and the 14 basket is an upgrade in function, not a fix for a defect. And Yamaha doesn't consider the 14 basket to be retrofittable to the 12/13 - if you look up the clutch basket for the 12/13 it doesn't show it superseded by the 14 type. You're not going to get a 12/13 basket upgrade to a 14 under warranty anymore than you could get a 12/13 engine upgraded to the 14's power level, at least not without something happening outside the normal rules. The 14's new basket is an upgrade and if you want this upgrade, you have to either pay for it yourself or get a 14.

Motorcycles improve with successive generations. If you want these improvements, then buy the new one.

Ya but, just because one dealer said something, it doesn't hurt to bring it up again to Yamaha. Who knows, They may supercede the 12/13 basket for the 14 at some point.
