Second post today!
« on: October 14, 2017, 10:42:59 pm »
I'm sure this has been answered somewhere here in the forum. I've looked and I'm almost positive I know the answer. But this is more of affirmation post. I noticed that when I'm on the freeway over 65-70 the bike wants to 'wiggle'. Is this what everyone refers to as wind buffeting? And this is fixed with a new/ shorter wind shield? I'm 5'10" and I have a rifle now. I added a vent today and it didn't help. I've been considering a madstad. Will that fix the issue?

Start with tire pressure.  Low tire pressure will make it wiggle.  Not having the suspension set up correctly will do all kinds of funky stuff.  I love my madstad, but I don't believe that is your problem.  Buffeting in my definition would be turbulent air from the windshield  rather than a smooth flow of air.  You might also snug up the steering head bearing if other things don't help your lack of stability.

I will check the tire pressure. These are brand new tires but the bike did sit for a month while I got her road ready. I'll definitely check the steering head bearing.
I've kinda had this effect happen before. I used to own a royal star tourer and it would kinda shimmy at higher speeds. But I ended up trading it for my raider before I could figure it out.

Avon storm. They are great tires. Definitely help make the bike feel more nimble!

Checked the tire pressure. 32 front 41 rear. The head stem nut won't budge so I'm guessing it's good. I haven't checked the front suspension settings yet but plan on it.
I should probably be more clear about the wiggle. It's not the beginning of the death wobble. I noticed that the front or the bike not the handlebars move. It's just feels as if my bike is being pushed around on the road over 65 mph. The roads don't have any grooves or anything like that so it's not like it's following the lines in the road. Feels like a strong breeze blowing me around.

I think 32 is a little low on the front? 38/41 is what I used to run on my C10 with the Avons.

   My first Concours was a 1988 and that one had a wiggle a highway speed. Finally adjusted the front forks to a stiffer setting and that solved the wiggle problem on that Coccours. At highway speed the wind pressure pushed the front forks down and caused the rear end to be light. Wiggle!  :-[

I'm definitely gonna check it now! I never got around to checking it when I had her a part!

The head stem nut won't budge so I'm guessing it's good.
 

The steering stem is adjusted with a spanner wrench.  If you just tried to tighten the hex nut on the top, you did nothing to the adjustment of the steering stem bearing.  If you did use a spanner wrench on the collar, then I suppose it's possible they could be too tight.  Check the factory shop manual for instructions on how to adjust.

I found the 3dxm Avon storms do best at 36 lbs . Mine felt pretty unstable until I put a couple hundred miles on them and set the pressure to 36 .

Bud- I have a shop manual. I'll take  a look at it toast to make sure it's tightened to spec.

Cra- I'll adjust the pressure and give it a shot. I think the tires have 30 miles on them so far. Looks like I got to get riding!

So I pulled out the manual to see exactly how to tighten up the head stem. I've been having a click every time I use the brakes. Turns out that this a sure fire sign that my head stem is loose and needs to be tightened. I ordered a spanner wrench and hopefully I can get to it this week. Thanks for the advice.I would've never even thought more into the suspension. I was almost certain it was the windshield. I did already tell my fiance that it's a windshield issue, so I may still buy a new one  >:D !
