Experiencing sensitive steering and handlebars wanting to wobble at 45mph+
I just bought a used 2020 390 adventure. It’s got 7300 miles on odo. I reset the suspension back to factory settings on the front forks (15 clicks on both from right) and the rear shock preload is at the stock 3rd setting. I don’t have any luggage or weight on the back of the bike. I weight 175lbs.
I also checked the steering head bearing and it seems to be fine and tight. But at high speeds the bike feels too unstable I’m scared to go any faster as I want to do some highway trips. The tires are the stock ones and have a lot of life left and it doesn’t seem to be unbalanced. I just tightened my chain and did the alignment too as I thought that could be the issue but it didn’t make much of a difference. (Also I took the windscreen off in the photo to clean it, has been installed again)
Any ideas? I’ve read other people have these issues and then others don’t and the bike is super stable.
