Actually, when I let off the trottle at high rpm the revs immediately
decreases, but more so than it should normally do, as if the engine
completely stalls for a moment. Thereafter it just decelerates
normally from engine braking.
Besides the slight lack of power, it never behaves strangely under
acceleration or at wide throttle openings.
It does, however, sometimes hesitate at high rpm's and small throttle
openings, as when going down a hill while cruising at say 120km/h.
Anyway, I'm dropping the bike off at a dealer today to see if they
can solve it.
I'll keep you posted on their findings.
Thanks,
Sef in the RSA

attempt to describe it again? Are you saying that when you let off
the throttle at 5000+ RPM, engine revolutions do not instantly begin
to decrease? And then after a second or two, the engine braking kicks
in, more than it normally would?

checking valve clearance is very easy. There's one more thing I
suggest checking: the carb. While servicing it, you could have
dislodged something and it's now causing the slide to stick. This
could explain why the bike is a couple seconds slow to throttle down -
slide stuck "open" - and the opposite with the sluggish performance -
slide stuck "closed".
