My GS wobbled too with knobbies on pavement.
The steering damper helped.
You can ride my bike and see if the damper helps you and if you want to invest in one.
No, you can get that wobble on street bikes as well.

So what can I do to cure the wobble???

Mine wobbled just like yours at 70. Then...

Lowered the rear end by adjusting the spring. Took almost all the tension out of it with the bike on a lift. (no, it never bottoms out)

Can go 100mph+ now and I do not drop it as much with the seat a bit lower.

Running TKC80 and do not balance them, no rim locks.

You are stretching the rake.

Worries me also...
My 2012 will do the same thing under certain wind conditions. A crosswind affects my up-wind shoulder and about 70mpg the front is subject to a wobble. It comes from my shoulder, but clearly indicates the front is pretty sensitive at higher speeds. However, it either disappeared or I've not had the same wind conditions...

I think it was reduced after my suspension broke in. After about 500 miles my rear rides a lot lower then it did at first. That extends the trail dimension on the front end, thereby slowing the steering and reducing the chance of high speed wobble.

If you want to extend the trail dimension, you either raise the front or lower the rear. The poster above took out a lot of rear spring pre-load, thereby lowering his rear ride height. That does the same thing for trail.

Look at the top of your forks. If their is room to slide the forks so the caps are flush with your T clamp, you can slide them down so they are. That will produce a higher ride height in front and increase your trail and it doesn't take much.

After doing all that you will be looking for more spring in front to hold the bike higher. You suggested you were heavy, so maybe do that anyway.

My old 950 was sensitive like that too. I attempted to lower the saddle through lowering the front by sliding the fork tubes up in the T clamps...Wrong!!! Big scary wobble above 90mph. I quickly put it back.

I installed a Scotts damper the other day on my 690, but have it on full off right now because I want to test the bike at different damper settings before I use damping. I haven't had time.

Google up Rake and Trail. The results will reveal what rake and trail is and how they impact the steering of a motorcycle.

I'm no expert either but I've fielded supersport race bikes for many seasons, and learned a little about it during test sessions in watching the tuners and riders trying to get the motorcycle to handle like the rider wants. Pretty fascinating. Of course, those bikes are fully adjustable in that way.

The black junk is just from the carbon brushes and stator. The failure has nothing to do with that, it's the piss poor wiring for the brushes.

Hard to start

My 08 690 has developed a case of the hard starts after it sits in the garage after a few days to a week. It takes about ten attempts to start now. Am I looking at a dirty injector or a fuel pump?? The bike runs great after it starts and it will start on the first attempt after you get it started the first time. I am ashamed to say that the bike only has 4,000 miles on it.

They're sensitive to low battery voltage. I'd give that a check first then move on to the injector then the pump.

Seems like it all should stay together,crossing my fingers

Wish I new about that .

Mine ( 08 ) started stalling a bit & felt lean & down on power , replaced the filter , no change , put a fuel pressure gauge on & it only had 20 psi pressure . This pump ( original ) always gave the whir on starting & never stopped . Replaced the fuel pump & all is good . Hope to dissect the original pump soon & see what was causing the low pressure . But plenty of black stuff in the filter .

I do not believe that. I only had black stuff in there the first time I changed the filter (8000km). Next times (2x) clean filters, still on the original pump (22000km) and running great. I think the black stuff are left overs from the production of the tank.
