hey peeps, i guess many of u kno much more abt cbr than i do & hope sum1 cud help me out wit an issues i hav
recently, i hav noticed in my cbr, when im shifting betwn 1st-N-2nd, many times it doesnt shift properly. I mean if i shift it to 1st and take off, at times the gear itself falls back to neutral without me doing anything. and same with from 2nd to neutral
It only happens between those two and 3,4,5,6th gears are all fine.
initially, i thot it might b me not shifting properly, but at times when in traffic and specially at turns, when i am a little bit in lean expecting that the engine force will balance me out, the bike drops to neutral and i tend to loose my balance on low side, luckily i managed to get it controlled witout any big trouble, but i am kinda getting worried as this thing is happening quite often.
Also, when i park it in neutral, its in 1st or 2nd gear when i come back...sometimes, its in neutral itself, but the gear indicator green light isnt on....so i have to shift it to either 1st or 2nd and then bring back to neutral

my bike is due for its 12000 km servicing and i am going next week, is there any heads up any1 could give me please... as i am purely mechanically illiterate and i dont want those mechanic to take any advantage and fool me regarding the same...
thanks in advance..!!! :-)
