I have had my beloved ZXR L9 (2000) for 5 years now, not done huge mileage, however I have looked after it' literally like a baby

Has anyone else bothered?
The bike I think is on 15 thousand (can't be precise). So a calculated guess would be more inclined to......not necessary, if I was going by mileage competed / equal to year if bike.
I'm by the gas fire and the bike is outside! So can't bothered to shift!

Any direction welcomed
Thanks Raj
P.s. Happy New Year All.......(if it's not too late to say such a thing)!
