I doubt that is the wheel that is wobbling. probably the tire getting a
slight grab. Around here we have grated briudges, rain grooves, plastic
glue on lines. all of them pull at a bike tire and make it feel like
something is wrong.

Never heard of an "infamous high speed wobble" on guzzis either...did I
miss something?

Subject: high speed instability


I would like to know if any list members have experienced the infamous
high speed wobble on their loopframes and would be willing to share this
experience with the group.My eldo is currently shod with Conti Blitz
tires,and sports wixom bags,trunk and Bates 700 fairing.I have ridden
the bike at an indicated 90mph with no hint of instability,although i
can feel a little bobble in the rear tire when crossing over painted
lines on the highway at high speed.Im wondering if the reported episodes
of instability are a sudden event or are they caused by a dynamic set in
motion by a rear wheel bobble such as i feel on my bike when passing
slow moving vehicles on the highway.Would appreciate any info.Next
weekend at Gunstock Ski resort there is a vintage bike show&swap meet on
Sat.,vintage roadrace on Sun.,and an awesome hillclimb event on
Wed.Check out www.gunstock.com for info.Hope to see more than than one
loopeframe there this year.Will post pics in a couple weeks.Thanks Scott
K.
