Hi, all. A few months ago I posted a message regarding a vibration/ oscillatiion picked up in the bars of my 1989 gl1500 when travelling at speeds of 80/85 mph and above. I recieved a good few suggestions as to what may be causing this, however I still have the problem. I have tried the following:
1) steering head bearings checked/ tightened.
2) fork oil changed (progressive springs with 15w oil)
3) Tires balanced and wheel bearings checked
I am beginning to think this may be a tyre problem, although the Avon Venom x tyres are still in reletively good condition, with no signs of cupping etc. The other thought running through my head is that maybe this is common to progressive fork springs with 15wt oil, and perhaps 10wt may be better. I like the handling of the bike with the 15wt. Any comments from owners who have installed the progressives?. The vibration definately increases with rise in overall speed and is not RPM related, as I would have noticed when accelerating through the gears.
Thanks in advance
Joe
