Hi MQonNinja,
I just bought (only got it just over a week ago) a Ninja 250 aswell! Same colour and everything.
You said your manual says
' in fist 800kms don't rev above 3000rpm'
, mine says don't rev above 4000rpm but anyway, i'm still in my "breaking in" period too and i've been mainly sticking under 4000rpm but i have to vary it a fair bit because of the area i live in (some hills, funny corners etc). basically i try not to even look at the taco and i just change when i need too depending on the road conditions otherwise i just get too paranoid and instead of looking at the idiots around me, i'm too worried about how many rpm i'm doing, though i have never gone above about 8000rpm (usually i'm around 4-6thou)
sometime when i shift down from 3rd gear to 2nd gear the bike is like at neutral and i have to ease the clutch a bit to make it back to the 2nd gear. is there a problem with the bike or just because of my inexperience?
i've only been riding for just over a week (havnt even got my L's yet) and I havnt had this problem, i think you may mean that when you go frm 3rd-2nd it's not actually IN neutral, but when you use the throttle all it does is rev and your speed doesnt increase??? if that's the case, i was told a "trick", when you change gears, instead of just flicking your foot up/down to change gears and then resting it back on the footpeg, actually hold your toe in the position of the gear you want and then ease off the clutch before you move your foot back as sometimes you don't actually select a gear.
I'll be getting my L's next week, so if you ever want a Learners/Losers ride let me know.
hope this helps
