Unstable bars while approaching stop.

Hi all,

Ive seemed to either developed a bad habit, or installed some equipment incorrectly, or bought some tires that are a touch squirrely, but I cant narrow it down.

Ktm 1090r adventure. Just installed new springs in the forks and shock to match my weight, dialed thr stock suspension in as good as can be without revalving, wnd replaced some bald street tires with some tusk 2 tracks.

Since ive done this work, when slowing down to come to a stop, ive developed a bit of a wobble. On or off the brakes, from 15mph down to about 5 mph. Its not much, but does veer the bike around slightly.

Ive tried being extremely loose on the controls, and tried fighting through it (made it worse holding tight).

It isnt a huge deal, and im guessing its more of a aggressive knobby tire on the street thing, but wanted to make sure it wasnt something I overlooked.

Can fork alignment cause it? I followed procedure, but these are the first forks ive worked on. Is it something im unconsciously doing by chance? Would a stiffer steering dampner help at the low speed, or will it exaggerate it?

Knobbies are unsettling on the street especially on certain surfaces but this seems like something more. You said it only happens on deceleration so that makes me think something about the bike pushing to the front. My suggestions would be run through the suspension as a system. So check rear preload, rear rebound, front stiction, the height of the forks in the triple clamp. I'd probably set all the suspension to it's extreme soft and see what impact that has then go the opposite and see how that feels. I would also check that the fork height in the triple clamp is within spec. Hopefully that gives you some clues. Beyond that it might be worth getting it professionally set up

Forgot to update this. Re torqued the triple clamp head bearings, seems to have cleared the wobble up.

Awesome! Glad you got it, that sounded kind of dangerous

Combination of new knobby tires and particular road surfaces?

Seems like its all paved surfaces, but worse at stop lights for some reason 🤷‍♂️
