I've had Bonnie since July and haven't had any handlebar/mirror vibration issues. It's been a cold and snowy several weeks here in the mountains. The weather, combined with some travel, kept me from taking Bonnie out much. In fact, for a four or five-week stretch, she got one 10 mile ride and a couple of five-minute idles in the garage. A couple of weeks ago, I filled her up with stabilized gas. Temperatures have dipped as low as 15 to 20 degrees F.

Yesterday I let Bonnie stretch her legs over thirty miles or so. When I got on the freeway, I noticed substantial handlebar and mirror vibration. As noted above, I had never experienced any bar/mirror vibration before.

Why the vibration now? I've read that carbs that are out of balance can cause vibration. This wouldn't be my problem, would it? She was running fine before I had to let her sit the last month or so. :???:

it's an easy diagnosis, and the carbs could always use a fresh sync.

Might as well balance them, maybe run some Marvel Mystery Oil through a tank as well.

Did you check tire pressure before taking her out?
that will affect it

Have you checked the tire pressure? If you can't ride it, I would not start it and let idle... The plugs can foul easy with to much choke...

I vote that you add four ounces of Seafoam additive to a full tank of gas, check your air pressure, and after fifteen minutes of riding..... start to RIDE IT LIKE YOU STOLE IT! That should clean out what's clogging one of your carb's....

I would check the tire pressure, and the handlebar mounting clamps, as well as other engine-to-frame bolts.

Thanks for all the suggestions. I did check the pressure and fill the tires immediately before going out. Is Seafoam additive like/the same as Marvel Mystery Oil?

Been raining here 4-5 days & now 40-50 deg. Went for a ride today. I let her sit & idle w/ the choke on 3/4. When I went out on the road she sputtered, backfired, & vibrated some before it warmed up fully. I think I fouled a plug a little & it took a good blast to clean it up? The plugs have never been oughta the bike , so I think it might be time for some new ones or clean & re-gap? Once she warmed up fully, ran better than ever! The nature of the beast I guess. Some overdue inspection also in order? Bonne's dont like to sit & cold weather.
