Hi. I just got a pristine (3300 miles) 2000 W650 last week. I'm not
new to bikes, and currently have 5 in the garage. I was a little
surprised at the level of vibration that the W has, since it has a
counter balancer. The reviews I have read either don't mention
vibration or describe it as "mild". On mine, vibration builds until a
peak of about 3500 rpm, then slowly decreases until passing 4500 rpm.
I don't believe my '69 Bonneville was any worse. The bike runs
perfect, motor mounts are tight. In fact, it shows little sign of use
at all. Is this normal for this machine, or am I just too used to
modern machines and it seems worse than it is.

Does the engine show any signs of havin been disassembled?

Congratulations! I think you're just too used to modern bikes.

of the charm. The W's engine design is like that of the old

and the counterbalancer is designed only to kick in after about 4500

My mirrors shake between 2500-3500 revs. and I feel a handlebar

you should check the carb synchronization, it could be out a bit - this
causes some increased vibration. Other thoughts include tires, wheel
trueness, tire air pressure etc.

No sign of anything having been disassembled. Not burred screw or
bolt heads, not a scratch on any part anywhere. Tires show their 3300
miles, and that's about it. Perhaps like the old Triumphs I just got
one with balance factor not as good as it could be.

Well, I found a good answer. Yesterday I made a 5/8" x 5" steel slug
for each handlebar. I cut a groove in each end of the slugs for an O
ring (11/16" OD x 1/2" ID x 3/32" thick), put a little silicone seal
on each end and inserted in the handlebar until it was recessed 1/4"
in the grip area. Sealed the end good with silicon seal, and presto!
About 2/3rds of the vibration is gone. Just a enough low frequency
vibe to let you know there's a vertical twin in there. Much better
for someone with carpal tunnel problems.

Watch the carburetors at an idle and you'll see the need to
periodically synchronize them. The rubber boots move quite a bit

and aft and that seems to knock them out of syncronization.

I could feel an increase in vibration as the miles accumulated, so

the syncronization every oil change. It ALWAYS reduced the

substantially.

Just my two bits worth.
