shaking it's head

[Gnasher]

Hi all, sorry to resurrect an oldish thread but noticed mine doing the same today and wondered if the lack of bar ends may be contributing? Its got heated grips and the bar ends are not fitted (done before I owned it), it is also a 2001 model so has preload, I did wind in the preload a bit earlier this week and again,  I wonder if this could cause it?, i have wound it back out now and will check it on the road tomorrow, any guidance or advice welcome as it is a bit disconcerting, especially as I like to ride with quite a light grip on the bars :eek


Thanks in advance Jonesy 

Bar end weights will do nothing they are there to deaden vibration through the bars.  Jacking up your preload can have a impact as you are reducing/steepening the head angle to a point but you'd have to go some to make it start shaking it's head.  Check the headraces as if they are loose/worn they will be far more sensitive to any shock adjustment or tyre wear/pressures.
