Low speed instability 1500.

Postby Rob H » Wed Jun 03, 2015 8:49 pm



Hi Guys.
Have a question regarding low speed stability 1500.

At a low speed fully loaded I am acutely aware of a wobble from the front.

Best way for me to describe it is that it feels like the forks are twisting.

No play in steering head bearing
No play or noises front wheel bearing
Tyre does not have any strange wear pattern(Dunlop E3) pressure at 2.5 bar(metric)

When the bike is not loaded it is still there but not as noticeable.

On a trip at the moment so can't do a huge amount, just want so ideas.

Thanks
Rob

Hi,
Nice picture of you and daughter. Do you think that the front tire might need to be balanced? Maybe some Dyna Beads. When you get the front tire off the ground, and give it a spin, does it stop at the same place on the bottom. Mark the tire and see if it might be out of balance. Maybe check tire pressure too. That's where I'd start. Oh, when ever my wife and I go out, someone always says that to me " Oh out with your daughter are you," so I really had to say it to you because I never really get the chance. Good luck fella.

I don't know whether your 1500 has a fork brace or not. They do make a huge difference. My 79 needed one. Without it, the bike felt as if it had been fitted with PVC pipes for fork tubes. It was back in 2000 when I bought my first Goldwing. I asked my brother who had ridden Goldwings many miles, he suggested I invest in a Superbrace. I did, and it made all the difference in the world! Do a netsearch for "fork brace" or "superbrace". It's money well spent.

I had a look yesterday afternoon when we arrived in New Orleans, it appears to have the standard arrangement on it.

Not sure if there is a shop here that would sell a brace. I will do a quick internet search. Leaving again tomorrow again so not a huge amount of time.

Thanks for the replies

Rob

If you bring your front tire pressure to about 42 PSI and make sure your rear shocks are on the higher side as far as pressure it should greatly reduce if not remove the wobble, also make sure your rear tire is at max pressure. when I ran E3 front and rear I kept my front at 42 and the rear at 44, I travel 2 up and pull a camper so I would keep the rear shocks at around 85 and that would keep the head shake away

Are you going to be in or near Oklahome City on your trip ? I would love to meet up and visit some and ride some.
I second rhe motion on the brace, I have not added one to this bike yet, but on other bikes it made a HUGE difference !
Reputation is what other people know about you. Honor is what you know about yourself. Our stress about it happens when the two aren't the same. Be true to yourself and to hell with what everyone else thinks!

Steering head bearing is loose
