Re: [ST] Re: RS neutral switch

["Knowles" <gpz900r@xxxxxxxxxxxxx>]

Hi
I don't know if this is linked with the fast idle but when my ST warms up
there is a noticeable "Click" from a solenoid of some sort under the tank as
you open and close the throttle when moving in slow traffic - it's as if the
solenoid clicks once when approximately 2k revs is reached and clicks again
if the revs fall below that as if it's closing and opening an airway or
something.
By the way my bike runs fine (touch wood) it's just a passing thought this
may be linked in some way to the threads of fast idle.
Anyone?
Paul
