  1. Mine is also a 2013 Factory with high compression head.

    I rode this bike a LOT at least 130 hrs.

     

    When I got it (used) the clutch was adjusted incorrectly and slipping. It had already

    eaten a clutch by the time I got it. 

     

    Clutch fiber running through the mains is probably not a good thing who knows

    if previous owner changed the oil, it looked very bad. 

     

    I also went 20 hrs or so between oil changes, looking back I would

    have decreased that to 10 or even less.

     

    I also have an hour meter on my bike now to be able to watch 

    things more closely for maintenance reasons.

     

     

     

  2. I could post a video of the noise tomorrow but have run several trials

    with it and almost everyone agrees it sounds like lower bearings.

     

    Checkers commenting saying they could hear me coming.  :chairfall:

     

    I put a dial indicator on the flywheel and have .008" in and out play

    and .010" lateral play (when considering both opposite directions)I am pretty sure that is not good.

     

    Here is some video what say you?

     

     
    First video was in and out, second was lateral, could have gotten more if I pried
    harder but did not want to damage the flange in the case.

     

     

     

     

  3. My green baby is sick and has a lot of bearing noise.

     

    I believe the top end is fine the bike has a ton of power 
    and not a ton of time on it. 

     

    Assuming it's only the lower bearings can anyone help me out and tell 
    me what parts are needed to swap out the crank bearings?

     

    Anything else I should do / buy when in there?

    Best place for parts? LewisSport is out they are at SSDT for 2 wks.

     

    Input appreciated.

     

     

  4.  

     

    mark did you install your xiu rdi adjuster. maybe i will visit next weekend. 

     

    Not yet, just planning ahead. Does not look like it will help me anyway.

     

    I did find the clutch thickness specs.

     

    Check the flatness of the clutch discs, and the total thickness of the pack (3+2 discs). The minimum thickness is 9’75mm

     

    Found here page 60;

    Will get it apart this week and put a mic on it.  Will check those levers too 

    as suggested above. Forgot I still have the plates from my previous clutch

    replacement so they may also be of use.

     

     

     

     

     

     

  5. Thank you lineaway, very informative. 

     

    Are you reasonably sure the measurements are the same for the

    OSSA clutch as they are for the GG in this video?

     

    Everyone who rides my bike is amazed at how hard my clutch is to actuate

    I get arm pump during trials. Fixing this would be a big help for me.

     

    I have a buddy "BIFF" with the same clutch (or very similar at least) in his GG and his is easily 3x as easy to pull as mine is.

  6. Sigh... 

     

    So after being all excited about getting my adjustable clutch ring it appears it will not help me at all

    unless I am thinking backwards.

    Technical info: Clutch control is the commercial name for this special adjustable spring clutch support plate. With 3 different mounting positions. Changing from position 1 to 3 you can choose different spring clutch pre-charge. From num.1, the lower, to num.3 the higher spring pre-charge. Position number 1 is the same spring pre-charge like original spring clutch support. Check recommended use and mounting instructions included in each products. Stainless steel screws are supplied in each clutch control set. Due its conical profile improves oil flow into the discs. Improving the cooling and reducing the wear. With this clutch control XiuRDi offers a completely new adjusting solution to trial high level riders. Precision and control are its main definitions. Recommended use A.-With new friction plates you can start with position num.1 or 2, depending your preferences. B.-After some working time, pads will be adapted and will be thinner. Then you can choose a higher number, until position num.3.

     

    My clutch is somewhat new and too thick and that is why it's pulling very hard.

    This ring seems only to help maintain the clutch feel when a clutch gets worn.

     

    Am I wrong?

     

     

     

  7. I need some thinner steel wear disks for my OSSA 2013 factory 300 to get the thickness down for an easier clutch pull. 

    If I can't find thinner plates for the OSSA clutch are they the same as a GASGAS clutch?

     

    If so what bike?

     

    I wanted one of those cool XIU adjustable rings but can not find them in stock anywhere.

     

    This leads me to another question would the XIU ring for the Gas Gas work in an OSSA?

    Tnx.

  8. My last few trials have been in wet conditions and once my gloves are wet they get slimy and slippery.

    I end up getting arm pump and or very tired hands because of reduced grip.

     

    Using renthal Medium compound grips and I like them but they are for **** with slimy gloves.

     

    I've searched for this and did not see any recommendations.

     

    Anyone have a glove that is tacky even when wet?

     

     

     

     

  9. I find it easier to hop both wheels at once than I do to hop only the rear. No doubt I need to practice it more.

    Basically it all boils down to practice, it took me many hours to be able to hop the front and I rarely need to in the class I ride (intermediate) but

    it's sure nice to have it in your bag of tricks when you do need it.

     

    One thing I observed is that you really need to get it down completely before it's of any real use to you 

    and does not cost you points by trying to use it. Much easier to hop when you want to than when you "need" to.

     

    For this reason in my practice I often try turns I can't make WO hopping and then hop it's more realistic.

     

    JMO.

  10. I recently heard from a friend who said he heard from a

    reputable source that OSAA is going out of business.

     

    Story is that GasGas had purchased Ossa some time ago and

    had been having trouble. They can not afford

    to save both brands.

     

    Anyone have any info on this?

     

    I LOVE my Ossa and can't imaging anyone letting all the R&D

    that went into creating this fine machine go to waste! 

     

    If it happens, what about parts, re-sale value, etc.

     

    Input?

     

  11. I spent over 40 hours in my basement over the winter doing nothing but static balance. 

    It was a huge leapfrog forward for me in my riding.

     

    half hour a day, the hours add up fast, can really help a newer rider IMO.

     

    I don't get nearly as tired while riding now because I can actually balance without expending a ton 

    of energy.

     

    I have atrial fibrillation and I can get tired fast when working hard. When I first started I was pretty discouraged, did not think

    I would ever "get it".

     

    These days it's not so much of an issue as I ride more efficiently, riding when tired will cause you to make mental mistakes for sure.

     

     

     

     

     

  12. Clutch becomes heavier on these if the fibre clutch plates swell,which sometimes happens if ATF is used in the gearbox .You need to remove and measure the thickness of the clutch plate pack which should be 9.85 mm max .You can get thinner steel plates to achieve this Theres info on this on the GasGas forums

     

    I've not used ATF but the clutch has definitely been dragging more lately despite adjusting

    the MC to max stroke. Pull seems harder too than when I put it in at the start of the season.

     

    I'm going to try one of these rings to see if it helps, will report back when I've ridden with it.

  13. I can not imagine riding with more than one finger on the clutch. I have a hard enough time hanging

    on with the 3 I have left when the **** hits the fan.

     

    Clutch grab in as close to the bars as possible helps, as has been said. I find that shorty levers help too

    to keep the outer fingers from getting smashed.

     

    When I started riding single finger was not enjoying life, he was weak and fatigued easily.

    Now single finger is a bad ass and bows to no man except during longer clutch heavy riding sessions.

  14. Is this for reducing / increasing clutch pull?

     

    I've been having some issues with arm pump during long practice sessions 

    would like to reduce the pull of my clutch a bit as my Ossa's pull is about 2x that of my Sherco.

     

    I'm a novice rider and won't be doing any 4th gear splats for some time I imagine...

     

    Anyone know anything about this? Seems like a new part.
