Vibrating
bars..this is surfacing with regularity. There are a few
reasons why this occurs and a few checks you can easily make the process
of elimination easy
- Check for
tyre/wheel balancing IF the vibes are not
engine speed related (see section 2). Simply go to a local bike specialist
of workshop and get your front tyre balancing checked out, this is very cheap and
very quick. If this is done with complete precision, then this will
sort the problem out. Only trust a reputable and well trusted workshop!
Whilst you are there, the workshop will advise you if your front tyre needs changing in relation to cupping effects,
although you would probably have checked that already. Cupping does
have undesired effects on your bars and general handling of the bike.
- To check
for engine speed related vibration, simply fire your bike up and sit
on it. Increase rpm and feel for vibration, the same vibration you are
concerned about. If this fails, then go for a ride, but check RPM level
when the vibes kick in - if the RPM reading differ in terms of speeds
then it is NOT engine speed related, but more likely to be either tyre
balancing or clutch basket symptoms. Obviously engine RPM speeds never
match the speed of clutch basket rotation.
- Steering
head bearings. Get these checked out for play (free-play). These generally
do not give vibration problems as such but can give some riders this
impression, depending on road surfaces, so get these checked out too.
- Bar ends.
You could try fitting a set of aftermarket bar ends, the heavier, the
bigger the better (all within reason of course!!) What this does is
dampen out most vibrations you are experiencing for very little money,
Give it a try, these can be purchased from most Motorcycle accessory
stores!!
- Failing all
of the above, it can only really be the dual balancer shafts that are
out of frequency, due to wear and tear. We would then recommend that
you get your bike into a Honda dealership for them to tune your balance
shafts to meet the requirements of the engine
