No i changed it in 2020 as in now..Bike is a Gen 1 2000 model and they had not been chnaged for 2 years
grin
years don´t really matter if milage is low -
they don't really age (in contrast to oils and fats)

i leave the usual sparks ( NGK CR 9 E) in my ´00 busa for around 12-15,000 km.
when she then starts not as fine as usual the sparks get replaced.

Yes that's good advice. I change mine every 2 years and there is a noticeable difference with fresh plugs..

To get to air filter box out the tank has to be pulled so far up that I always snap the wiring for the fuel tank indicator. Easy to fix again with conncetors but bear that in mind when doing this guys

hey man :)

tank has to be lifted at its front and holded up by the bowed "stick" (findable in the tail under the 2nd seat)

then pull of the 3 rubber hoses (flapper, crankcase vent & 2nd air) and loose the two long (~120mm) screws + the one (M6, hex 10) in front

pull the hose to external air pressure sensor and disconnect its harness-plug

that´s (as far as i remember) all you have to "unplug" to get the box off.

so what do you fumble with some other connectors?

edit:
did you already check the fuel hoses / replaced the original with the new ones?
if not youre in danger of stuttering motor when hot,
because the old hoses very often like to kink

here the ´00 no´s
art.-No. (hose 1) : 15801 - 24 F 10
art.-No. (hose 2) : 44433 - 24 F 00

and !
the new ´00 hoses also like to kink,
if you don’t watch out hellishly that even those new one weren’t bent when the tank was lowered .

Yes thanks hoses seem alright and never had a problem with them. The wiring is at the base of the tank near the battery and when you raise the fuel tank it stretches and disconnects .i then just reconnect it.

lucky guy
if you can find red dots at the hose = ´00 hoses = new(er) hoses
but if there are 2 white dots you still have the ´99 hoses.
(so written in my german manual)

I've definitely been allowed :banghead: :redface: to do this hose replacing 6 or 7 times in the past few years.
I then thanked the owner (ironically) warmly for the petrol shower, which is inevitable when you change the two hoses.
not funny at all - believe me - that bad gasoline smell everywhere.

but never forgett to watch the fuel hose´s behavior when lowering the tank - even the newest hose can kink.
that's exactly what I've experienced already myself . no joke.

the fuel back leading hose has to go between the crankcase vent hose and the throttle bar / cylinder.
this way it is shown in our ´00 supplement manual by a special drawing.
