V4 Ducati North America (dna) Vibration Complaint

  1. I figured that much and would also be a long dragged out process

    Didn't think of that, just thought of 4th gear not to hit the threshold, but 2nd or maybe 3rd would be a better test
     
  2. On the rear on mine, if I rotate the wheel to show the heavier set of weights at 6 O'clock there would be another lighter set of weights at the 10 O'clock position and on the other side of the rim (exhaust side)
    Assuming it's normal to have weights installed on different positions of the wheel on a Bike, and on both sides of the wheel as well? Since this is common on automobiles?
     
  3. I haven’t got any weights on the rear wheel, and my bike is solid as a rock up to 168mph.
     
  4. That’s not normal at all. I’d remove the wheel and all the weights and have it rebalanced. Weights should only be in one place which will be opposite the heaviest part of the wheel/tyre combo.

    Depending how many weights are used they may be spread across both sides of the rim but they should all be in the same o’clock position.

  5. Damn.... I'd be happy if mine was rock solid at 120 Mph

    Ok Thanks, thats what I thought (for bikes), just wanted to be sure, haven't manually balanced a wheel myself in the past 10 or so years and thinking maybe there's some new method of balancing, glad and the method of countering the heavy spot is still the method.

  6. Also might be worth looking if your tire has a red or yellow dot on it, if only yellow it should be next to the valve, if both it's more complicated
     
  7. That's most likely your problem.
     
  8. What's red dot again? I know it was covered on another forum, but really didn't pay much attention to it

    With all the input from the forum, it would seem it narrows down to this.... My current residence doesn't have a garage like my previous house, so I sold all my "shop tools" or else this would of been tackled already.
     
  9. The red dot is the high spot on the tire and the yellow the lightest spot.

  10. What are you supposed to do if a tyre has a high spot?
     
  11. Nothing. It gets balanced when they put it on. Don't fret.

  12. I realise your tyres will be Pirelli, I use Metzeler tyres. This is directly from their website so it should be correct. I can’t imagine different manufacturers using different colour codes but it’s possible.

    ‘Some Metzeler tires have a red dot on the side wall. This indicates the lightest point, and should be positioned next to the valve.’

    I would balance check the bare rim first and find the true heaviest spot, sometimes it is not the valve stem but it certainly can be. You then put the Red Dot which equates the light part of the tire to the actual true heavy spot or valve, therefore few balance weights are needed.

    It’s worth a try even if it’s part of the process of elimination.

    I’d check the red dot theory thoroughly though but… that’s what the Metzeler web site said. As I understand it Pirelli own Metzeler.

  13. Agree - for a light or a heavy point in a tyre. Weight is not going to sort a high point. Semantics.
     
  14. some wheels are meant to have a low spot marked, but I have never seen it personally, I agree it's just semantics but the OP is going through a nightmare by the looks of it and it looks to be balance related so now is probably not the time to gloss over the finer points I guess.

  15. Disagree. He has has fessed that his balancing weights are all over the place. Get the damn wheels and tyres balanced and take it from there.
    He's the only one with this problem!
     
  16. That's exactly the point...why has a new bike got balancing weights all over the place?You fit the tires correctly and then balance the wheel, in that order. That's all I'm saying. If he is the only one with the problem does it make it any less of a problem.
     
  17. Is it sorted yet?

  18. Not yet, waiting for it to get to 6 pages.

  19. I've read through the entire thread and can not understand how he has not had the rear wheel/tyre checked.... removed the weights and had the wheel re balanced by now

  20. Me too. Making a huge amount of drama and not even checked what anyone else would have done first.
    I'm now adding this to ignored threads.
