front end shake
« on: June 29, 2013, 07:43:56 pm »
 ??? So I just purchased a 2006 Concours with 12,000 miles and it runs well. Last evening after jamming through some tight corners on some less than pristine backroads up here in Alaska, I took my hands off the grips to shake them out as I often do and experienced a side to side almost tank slapping within a second from the bars. No clue what causes this. The machine corners fine and as soon as I apply pressure to the bars again everything is cool. I like to take my hands off briefly in a safe situation to shake them out but this was so immediately violent I do not dare. Any suggestions what to look for out there in COGLAND?

I am also fairly new to Connies but that shake is from the steering stem bearings. They likely need to be tightened, I also have to do the same thing. At high speeds no problem, but the 30-40 range is a good shake with no hands on the bars. Also depends on front tire pressure, too low doesn't help

Where about in Vermont are you? I used to live in Peru near Manchester with many fine roads nearby. I had a 2002 Connie there and never had any problems with it in over 20,00 miles. How difficult is it to tighten steering bearings? I was hoping for just a wheel out of balance or uneven bar weight, something simple since my mechanical skills are less than optimum. ???

Had this happen once, and yeah, intense pucker factor and as close to a tank slapper as I ever want to get.  While my steering stem needs some attention I know low tire pressure and bad asphalt "gators" contributed.

Hi guys. Lots on info on here about this. Tighten the steering head nut with a 40-42 spanner wrench, probably 1/8 turn and it will likely stop. Search for the threads. It's pretty common and easy to fix.

I was wondering why this shake would start so suddenly since there were no symptoms prior. It only shakes with my hands off the bars. If I just barely put some pressure on them it immediately stops. I checked the forks for looseness with weight off the front of the bike and can detect no movement. Tire pressure is within a couple pounds.
