Do you use the Yamalube??? Some people says it help to keep everything smooth, but is there a major difference with other premium oil???

A couple have posted that their bikes didn't really smooth out until higher mileage but didn't comment on the shudder/vibration question and if their bike has this symptom at a given rpm range. My bike has continued to run better and pulled harder as the miles have come up (now at 5K miles) But this has had no impact on the engine vibration in this RPM band. Perhaps you can comment on this aspect of your experience.
Things like this are notoriously hard to diagnosis of the net, but my experience is that like most big twins, the S10 really doesn't like big throttle openings under 3500 rpm or so; some of the problem may be simply lugging the engine.

+1, my bike before the ST was a Suzuki SV1000S, it's just the nature of the beast.

Actually, the SV1000 had/has the same clutch basket as the DL1000, so the potential for the shuddering existed with those too. It did not affect all DL's or SV's but when you had it, you knew it.

Thanks for posting that link Scott123. John is the guy who I worked with to fix my vstrom basket as outlined in the link and who I am discussing the issues I am noticing on the yamaha. I want to pursue an investigation and a potential fix if the ST basket has a similar design and wear issue leading to or creating vibration. Looks like several notice the shudder when coming up through the rev range and I would guess some are worse than others depending on potential factors (manufacturing tolerances, miles on bike, etc.) and also some of us are more sensitive to what the machine is doing and some of us are blessed with the ::021:: gene.
Just signed up to the forum today after a couple of weeks lurking with no intention to post for a while. Now the link to my work on the Suzukis is public I might as well be here to answer and explain anything if required. Ideal might have been for more owners to contribute here before seeing that. Avoids any auto suggestion the vibration in the ST engine is generated in the clutch basket. Similarly there might be those who wish to say it definately is not. Went through all that on the Suzuki forums to prove beyond doubt it was.scott123007 said:
Situation with the ST is no one knows either way just yet so please continue to contribute here with an open mind. Feeding back and capturing true owner experience of a new product is certainly something manufacturers don't do well. Particularly those which might show them in a poor light. Beauty of forums is they flush out the full picture in the end.
I am very keen to help prove conclusively if the ST clutch basket is the cause of this vibration or not. Please note the examples of wear given over there are extreme after many miles of owners putting up with the vibration thinking it was the nature of the beast. Some basket dampers vibrate when new and the signs are there inside from just off new. I can find them with a detailed strip down.
Realise its a long shot with such a new product. If anyone has removed their ST clutch basket for whatever reason, it would be great if they could lend or sell it to me for investigation. Conduct a non destructive invetigation. I would take pictures and share them here with all care what I found. Perhaps they could be modified like the Suzukis if found to have a problem? Perhaps not?
Early days perhaps. Lets eliminate the clutch basket so we can focus on other areas. I fancy one myself.
my clutch basket was replaced under warranty last fall. Sorry, don't have the original. Complaint was excessive noise at idle and a chirp and shudder when starting out in first gear. The motorcycle had the "vibration" at the 3200rpm +/- area. Replacement cured the excessive noise and the chirp/shudder when starting out. I still have the "vibration" but it is considerably less.sharealike said:
All the springs in the original basket were very loose with obvious lateral movement. Hope this info may be of use
How history might be repeating its self ten years on? Your experience could be exactly - I will repeat - EXACTLY - that of a VStrom or SV owner back in their early days. Manufacturers will often only credit the the dealer for parts and labour under warranty when the displaced part is returned. Prevents fraud but also makes certain the evidence is taken out of the public domain. Yamaha are said to be better at warranty than most. Lets hope your old basket gets back to the actual manufacturer in Japan (most made by FCC) and they investigate what was wrong. Suzuki tried three separate changes/revisions in the first four years that they thought would be the cure. They never found it. Perhaps an owner changed a basket themselves in a market where some bikes will be well out of warranty?elwood said:
All the springs are loose in the torsion damper of a new basket. Thats how they are supposed to be. Each comes into use as the load increases so its a progressive rate much like quality suspension. They also need to be free to rotate a little each time so they don't take on a set and wear is spread rather than concentrated. Dealers and owners blamed weak or failing springs as the cause in the DL which contributed to the lack of a clear diagnosis and fix. Only a hand full of springs in over 1,800 I inspected were broken or shortened.
Clatter at idle would come back in the DL and SV after some distance. The chirp and shudder when taking off only affected about 10% of the Suzukis. Part of the problem in the higher mileage and worn units I modified. Once I had the vibration I knew its character so became hard to escape. Modification to a bikes original basket always gave best results. So long as the distance from new was not too high.
Thank you for your contribution. Very helpful. Do you remember the distance on the bike when it was changed? Interesting to know if the dealer gave in straight away or you had to push them?
5000 miles. Had the dealer tech at Whitehorse Rally in Canada ride the bike. He agreed with what I was hearing . I asked him what he would do and without much thought said he would change the clutch basket. Conveyed the conversation to my US dealer who ordered the replacement part without even seeing or listening to the bike.sharealike said:
Several of the original basket springs had at least a 1/4 inch end play. IIRC none of the springs in the replacement basket had any end play however they could all be easily rotated
Plenty of the Suzuki 1000's had those same major problems with the basket by 5,000 miles too. Hard to believe at the time. Suzuki soon gave up changing under warranty when the time was up - "they are a service item sir" or "thats how they are sir" and "the latest version is now fine" were common responses. Owners were sometimes on their second or third basket in the same bike by the time they found me. Up till then a new basket at the same time as they changed the rear tyre proved annoying and costly. They never broke and let you down. Just hacked you off if it started part way through a trip.elwood said:
Depends which position the basket came to rest in as to how much end play can be felt in the springs. Its what the springs press against that moves out of the way in the problem baskets.
Nothing specific for the ST. The after market baskets still retain the original gear, spring and damper from your old basket so not much help. Even then they need setting up correctly so they don't have the same issues all over again. A few specialists do "locked up" baskets for racing but they will be rough in every day use.~TABASCO~ said:
Best results are with the bikes original modified. From 5,000 to 50,000 miles the SV and DL were good for the modification and lasted the life of the engine.

Managed to visit five Yamaha dealers near me intending to chat with the guys in the workshop. Hoped to see if they might have any experience of this vibration. Find two closed down over the winter due to recession. The other three say their sales and workshop experience of the ST is minimal. Original launch bikes in crates or on the showroom floor. Sales say they can't sell them as way over priced against the alternatives. The few they sold have just come back for routine service or not at all in the case where a bike was sold out of the county. Mileages sound small to date. UK is a small island relative to the USA and Canada......
I have been riding for 40 years now have owned many bikes and have done most of my own wrenching. I purchased my ST last March, I now have 14,700 miles on it. I have had the 3,200 rpm shudder since day one. It was a slight nuisance in the beginning and I have lived with it but a friend of mine bought a ST about 6 months ago and I got the opportunity to ride it and to my amazement, no shudder. Once I experienced ridding a ST with no shudder, I became more curious about the issue and have been reading all I can find and talking with other owners. My dealer has investigated the issue with Yamaha and they say that they are not aware of any such problem. I will be ridding this week and will try slightly pulling in the clutch to see how it effects the shudder. My bike is stock and I have chose to not start chasing every idea because I believe in time the real answer will be revealed.
Good information RAMLIN. Thank you. Please let us know either way how the slight pull on the clutch affects your shudder.
Did your friend ride your bike. Wondered if he felt the shudder?
It's often trying another bike that highlights how the annoying levels of shudder can creep up so slowly in the Suzukis. Never realise what poor refinement they were putting up with. Some said they had been adapting how they rode to avoid it without realising.

Rode the ST to work this morning, about 40 miles. I can say without a doubt that slight pressure on the clutch lever eliminates the 3,200 rpm shudder! I tested this many times on the way to work, in different gears, high load, low load and every way I could think to test the condition. Now, what does this mean? I don't have the answer to that but I am more inclined to agree with sharealike, the answer is not fuel.
I hope this helps...we may be onto something here.
