    From another forum ..
    QUOTE
    For sometime now myself and another member, paulinokc, have been trying to keep everyone informed with our trials and tribulations in getting Yamaha to take notice of the clunk issue. Today I succeeded!!!! Met with the regional service rep, listened to him state that he has not heard of any such problems, told him thats BS, heres my key, you ride it then we will talk. After a very short ride his first commit was "OH S**T, THIS AIN'T RIGHT". I told him everything I wanted & expected to be checked, spring tension/load, spacer length, torque of all front end bolts/nuts and (THANKS TO PAULINOKC) the head nut for cross threading.
    The head/steering nut was found cross threaded creating approx. a 3/16 inch gap at the upper bracket. This little nut is kinda important since it holds the forks to the frame, whudathunkit. Yamaha is going to replace both upper and lower brackets (trees), all bearing, races & seals, ect. Just over $900.00 in parts alone. I strongly urge everyone who has or have had this TYPE of clunking noise to get their bikes checked asap!!! Oh by the way, ain't no way in hell progressive springs will correct a cross threaded nut!!!
    If ya'll go back and look at the "famous clunk poll" you will find that out of 88 votes only 27%, 24 folks, thought this was a serious safty issue & should be fixed by Yamaha. I wonder why. I also got many personal e-mails telling me that I was holding my breath for nothing, did not know what I was talking about and that progressive springs was the one and only fix.
    NOTE: I honestly feel that there is several different causes for this clunking noise and in some cases the progressive springs is the correct fix. My case was different. We all need to be careful with the info shared on this forum. Lets make sure we have all our ducks in a row & properly spaced so we don't get duck do on their bills.
    The Yamaha rep will write a report of his findings & submit it to his boss,who inturn will pass it on up the line. At some future time there will at least be a service bulletin issued.
    Just in case I've p***ed someone off I take full responsibility for all the above.

    zumnckuj, thank you for the information - you have spurred me to take prompt action, where I had been saying to myself, "yeah, I need to get better springs - someday."

    I suspect you may be right - that there could be multiple causes for spring thunk. However, you raised a vital issue. All too often, some people make statements of opinion online as if they were Holy Writ. I've probably done it myself. We need to remember these can be life-and-death safety issues.

    Thanks again!

    This is a serious safety issue. I have personally been in contact with 2 riders with the crossed stem nut. Both are riding 2008 models - but I am not convinced that is limited to the 2008 year model. I ride a 2007 model and it has issues as well. My dealer has 2 used 2007 trade ins at his store with the same clunk as I have. Yamaha has a serious problem here and only in the last 4 or 5 days have they even admitted to a dealer it is a problem.

    The stem nut must be removed and the threads on the stem and nut must be visually inspected. The nut will torque to spec even if crossed.

    This is good news and bad news all at the same time. Thanks for your diligence in trouble shooting this issue. I was about to order PG springs but will now hold off and pay my dealer a visit.

    FWIW, I've tried an over-sized spacer in the front end and this has had no effect on the 'clunk'.

    I have NEVER said that THE ONLY fix is the progressive springs. All I know (and Morg and many others), is that when WE replaced OUR front springs with the progressive springs, OUR versions of the clunk went away totally.
    I would think that IF OUR stem nuts/whatever were loose the clunk would STILL be there, and if we jacked up the front end of our bikes, I would assume/think that at the very least you would feel looseness in the front fork/bearing area. If it can't be tightened down, it has to be loose causing the clunk, right? At least that's my train of thought............I do have a LITTLE automotive/motorcycle knowledge).

    Anyway, for sure if YOU suspect that your front end isn't right, get it the hell into the dealer and have them check it out. It IS a safety issue.

    Hey ogie .... can you provide the dealer and reps name so that when I go to my dealer I can ask them to call your dealer to find out whats going on and how to check for the issue.

    I want to go armed.

    My question is how could the stem nut get cross threaded on so many bikes. Is it a defect in the nut, stem or something else.
    I just made a 1400 mile trip to the Dragon and am going to Bikes, Bluess & BBQ this week, but now may reconsider. How dangerous is this?

  8. ogie
    #

    TribleM - How serious is it? If the nut is crossed - it may decide to turn loose at some point. The results could be catotrophic - as the stem holds the front forks on the bike. If it "came from together" at 70 mph...you get the picture. Go get it checked................ogie

    Hey Steve,

    Guys like you and Morg always bend over backwards the other way! You both demonstrate the kind humility born of wisdom and experience. My comment was in no way directed at folks like you, and I appologize if it seemed like it was.

    I am completely ignorant of these things, but I do know that similar symptoms can often arise from different causes. Your thunk may very well have been caused by the springs. Having said that, I would feel better if I knew that you had check to be sure you didn't also have the cross-threaded nut problem. (I hate it when my nuts get cross-threaded, don't you? ) It sounds like they may have had an ignorant or careless nut-threader working on the assembly line, and inadequate QC.

    No problem with the misunderstanding, (if it even was that).
    For sure everyone should get their bikes in, and have them checked out.
    I just had mine up in the air this am (washing it after its filthy ride yesterday......(some gravel roads.....UGH)......anyway, I checked for any kind of looseness in the front end, and found none. Doesn't mean that my nuts aren't cross threaded, but lard knows I've gone over PLENTY of pot holes/ruts/things on the road that would've made it clunk if it was going to.

    On the dangerous portion of the subject, I hope no one's doing any extended wheelies with their 1300s..............Then if the front end falls apart, OR if it's going to, it'd become readily apparent then!!!!!!!!!!

    (bottom line.......NO stunt riding your 1300s!)

    Steve, I am glad the communication lines are clear. But, uhm, Steve... will a 1300 actually DO a wheelie?? And if it will, exactly how do you happen to know this? Oh, I know, you saw someone else do one, right?

    Glad to hear that your nuts aren't, er.. cross-threaded.

    this is the most asinine thing i have heard. so let me get this straight. THOUSANDS of these bikes, sold WORLD WIDE, have crossed threaded bolts. and i guess we never landed on the moon and JFK was really killed but that guy on the grassy knoll. verbal diarrhea about some assembly line worker cross thread all of these bolts is just ridculious. have you told DOT about this? my God, if this is what you are saying it is, this is a company bankrupting negligent law suit, possible (if any deaths have occured) a homicided investigation as well! Mulder, you need to get on the horn to Washington on this one. DOWN WITH THE CROSS THREADER MANIAC! we should get his/her family as well so they cant spread the hate.

    Mine doesnt thunk or clunk, do all of them do it?

    Stilletto - No one knows how many have the clunk. This bike has several issues - springs / the clunk / clutch rattle. The information that we have available, approx 4700 built in 2007, 2008 numbers unknown, 2009 numbers unknown. What caused the locknut problem - who knows. design flaw or innattentive guy on the assembly line. All anyone has asked is for Yamaha to step up and fix it. No more - no less. Get a life!

    It all started a long time ago in a galaxy, far, far away. A good friend of all or us, (Morgmeister), when these front end clunk issues started appearing, decided to take it on his own, and replace the front springs in his 1300.
    Well, he did, he wrote up a beautifully elloquent piece of literature, documenting his discoveries, along with the fact that he was also told/and recommended to upgrade his front fork oil to 15w instead of the factory 10w.
    Well, all he did was replace his front springs with the progressive ones, and told us how HIS 1300 no longer had the clunk, and how much better the ride/handling was.
    I subsequently (along with dozens of other 1300 riders), also stepped up to the plate after Morgmeisterextreme's write up/article, and purchased the progressive springs and did the install.
    My clunk was amazingly gone/dissappeared/vanished as well.
    I heard of a few people that DID the progressive spring swap and STILL had a clunk in their front ends.
    MAYBE they are the ones with the crossthreaded stem nuts, I don't know, but I'd for sure (if the springs didn't fix the problem), have IT looked at quick!

    Now, getting back to the wheelie issue. Being as these bikes are more or less 50/50 weight, front to rear, and belt drive, (although I"ve seen HD's do them), I'd be kinda afraid to DO a wheelie, or for that matter, even attempt to do a wheelie on mine.
    I DO know that they will do a NICE burnout tho. (even from a roll on). Before I swapped the dunlop (read aka gag tire), and put the Metzlers on, riding solo, (oh yeah, this was before the smartpartzbaffles install too), I could crack it in 1st, and literally light the back tire. Great fun.

    I have seen a professional stunt rider on a Triumph Rocket III do wheelies down the road, so I would assume a lighter bike like ours would probably do one too...not that it would be advisable to try such a thing...

    I was looking at my front end and noticed that the right side cap bolt is around 1/8 inch higher than the left (above the upper bracket). Has anyone noticed this on your 1300?

    I replaced my front AND rear springs with Progressive springs some time ago. The front clunk is gone and the bike rides beautifully. The ride is much more refined, especially the rear spring where my arse can feel the most.

    The front spring was changed first and the rear, a couple of days later. Just with the front replaced, the ride was noticeably better, sans the clunk.

    The cross thread issue should be looked at first and the spring replaced if the clunk is still there OR if you want a better ride overall. Simple, no?

    All comments about installs or upgrades are based entirely on personal experience and it's there to be used as reference and an individual's result may vary for obvious reasons... We're all different and face varying situations/rides. Our only common denominator..? Our 1300s and even then it's a bit different from bike to bike. Some have problems, some don't. Is it the bike? Maybe, but it probably has to do more with our individual expectations. Some bike have legitimate problems like zumnckuj but like many of us, I haven't had any "major" (or I don't consider it major) problems like the "cross thread" or the clutch noise.

    I've upgraded some parts of my bike with little difference, if any, in performance/comfort but did it because another member installed it and recommended. I don't blame him for posting that information. It worked for him, but didn't for me... just like he fits better in a Levi's and I fit better in Lee jeans doesn't make his post less valuable. You have to be diligent and use all information in this site as a tool/reference and get the most out of it for your personal situation. As for me, I probably won't stop upgrading my bikes and cars and I'm hungry for more info. Post on!

    Good luck everyone!

    ttt153 I was thinking about replacing my rear spring for a softer ride and was wonder what spring from progressive you went with on the rear and if it gave the bike a softer ride?

    Thanks Tom

    I know that Progressive springs offer a few rear springs, but I got the ones that Pacific Coast Star sells. Here.

    The ride feels more "plush" if you know what I mean. You have to set the pre-load like the factory setup and adjust to according to what your ride configurations is like. I initially set it to 1 and would bottom out, so I adjusted to 6 and the ride is perfect for me (I'm 6'1" 220lb). In all honesty, I don't remember what the factory springs felt like anymore. All I remember is that as soon as I got it installed, I said "wow, what a difference".

    I had my mechanic install it for me and he said it was a bear to install. Paid him $150... Good price, I think.
