also consider your systems are ecu controlled
thus startup idle will go from 2000 to 1400
from cold.. having ridden say 30mins before,
idle will start somewhere above 1500, skipping
initial 2000rpm starting point..
my first startup routing for cbr250r was coming from
non fuel injected non ecu controlled motorcycles,
so i more or less started her up, lightly revved,
then took off.. this was coincidentally also the phase
of engine cut-outs, usually after hard acceleration
then rapid decel/braking..
after finding this forum i was educated to correct startup
by experienced members, including not,, touching throttle,,
allowing revs to drop from 2000 to 1400 before using
throttle, and then taking off..
after using this simple startup process, she began smoothly
starting at 2000 then dropping to 1500 then stabilising
to a nice 'heartbeat' at 1400.. [coincidentally
that engine cut-out phase faded away]
[i was using ethanol blend petrol as well,
so that could have been a contributing factor]
as for oil temp, operating temp etc,
what is measured etc, as members above..
my startup is usually [now cbr300r] the same
with ignition on, hit starter button, dont touch throttle..
then [with spare key] unlock chain and rear disc lock,
hop on board, don helmet, sunnies and gloves,
[not rushing it] 'test' fingers on lever movement,
relax shoulder blades etc, take a few nice relaxed
diaphragmatic breathes, check up/down/around,
hear a voice which says; 'righto, here we go'
then move up out and around arcing downslope
very smoothly and slowly, inside foot last up,,
lightly tapping front brake with one finger
before approaching first intersection..
until full oil circulation, your engines
mating surfaces etc, are protected only by
a thin coat of cold oil from your last run..
