So how come my bike doesn't do this? Or maybe I'm riding it differently . .
So (Adam), can you describe better when this occurs? Is it when you've already got
the throttle wide open and you just waiting for the engine to catch up, or does it
occur at the same revs regardless of the throttle position at the time (or the
throttle position just previously)?
My bike once used to have surging, buzziness and flatspots, but all that disappeared
when the bike was properly serviced by someone who knew what they doing (take a bow
www.flitwickmotorcycles.co.uk/) - and they didn't even replace the TPS or "adjust" the
computer, just got the throttle bodies back in sync, ran the diagnostics and replaced
a misfiring plug cap.
In my experience there is a world of difference between "a Yamaha mechanic" on the one
hand, and on the other "a Yamaha mechanic who did the special training courses for the
GTS and still remembers what they were told".
I certainly can't find any flatspots now, but maybe I'm just not enough of a boy racer
anymore :-(
