Hey esaraiva, :waving:Yes i will tell you whats causing your woobbbbllleeeee but like a lot of :18red:riders you wont take the advice. :whip: Take that Metzeler tyre off and throw it as far away as you possible can, :whip: and dont ever be guilty of putting such rubbish on your :18red:again. :crying:Fit the 709 Stone with 36/37psi and i will guarntee that your :18red:will not wobble at any speed. :weightlifter:Make sure the arrows face the direction of travel. :clapper:Can anyone tell me how to avoid the front end wooble that the GL1800 has between 30-40 mph?
I use Metzeler tyres and the recomended psi.
Redwing is right. Two things:
#1. Fire any mechanic that does not use computer spin balancing, there is too much rotating mass in these wheels for that nonsense.
#2 Had same thing happen with brand-new Dunlop. Replaced with a good Bridgestone and spin balance - perfect.
Dont buy the tale about loose head bearings, they cannot cause it, only amplify whats there.
My 1200 SEI has the resonant oscillation problem in the typical 30-40mph range common to many Goldwings. The SEI has handle bar weights inserted into the ends of the bars to lower the resonant frequency of this oscillation but it wasn't totally effective. You can take the weights out and scare the hell out of yourself because the oscillation will occur at higher speeds and at a higher oscillation frequency. Pre-loading the head bearings tend to reduce the oscillation frequency by reducing the frame/fork flexing. Front end flexing in the frame and fork is the main culprit in this problem. My old Triumph 650 of early 1950s vintage was a fine example. They had a friction plate with a handwheel so you could adjust the steering friction on the fly. If you were riding around town you could slack it off for easy steering and crank it down on the highway to keep things less exciting.Tightening the head bearings (from an engineering standpoint) does something called "damping an oscillating system". The "oscillation" is the handlebars going back 'n forth and "damping" is tightening the bearings to "dampen" or stop the vibration. Find a vibrating radio antenna on a car or bike thats vibrating and pinch it with your fingers - the vibration stops or changes radically.
Tightening the bearings cannot possibly eliminate a problem in the front wheel, the vibration is stil there, but now the bearings absord the vibration and destroys the bearing races. Then one day you wake up with handlebar shake you cant control and go in the ditch. BEEN THERE, SEEN THAT! Its extremely scary.
Hey Dave Campbell, :waving:Three days on the forum and promoted to "Guru" :clapper: well done. :clapperid you travel to Dublin for the Interview? or did the wingnut fly over to the states. :baffled: You must be in contention for the new :18red:your posts are flying. :clapper:First to 1000 posts wins the :18red:. Ride Safe. :grinner:Hey Dave Campbell, :waving:Welcome to the forum and visit often. :clapper:It's very easy to see that you know what your talking about.We have a "Guru" status on this forum:stumped:for members who are well up on goldwings :jumper:but something tells me that a higher title will have to be found for you. :weightlifter:
