heya..
just a month-old owner of a 2009 Pulsar 220 DTSi

i just feel i'm having some minor problems with my bike, which i guess should be really minor only , and can be adjusted easily.. just that i need all you people's help! (infact, these might not be even any real problems but as it is my first bike, so my queries might seem little n00by for you )

first of all, about the front tyre (which, if i'm not wrong, should revolve freely); when i rotate it manually (with my bike on the the center stand), it experiences some friction.. and a definite hissing-like sound. Is it really some problem? or the sound shouldn't be there?
one more thing to add is that whenever, during a ride, i pull the front disc lever, a can clearly hear a mild sound from the front end..
please tell me if something wrong!

now, the 2nd thing, about the rear end of the bike; i feel it too creates some unnecessary sound during riding. (i think it might be because of a tight chain, but again, i might be completely wrong for i'm completely new to riding my own bike)..
or maybe it's just the normal sound of the chain (which echoes good enough to be properly heard when there's some wall or reflecting plane, parallel to the bike, when riding near it)
this particular sound is sort of, like when there is some polythene bag or packet is touching the tyre.. maybe i can't explain it

looking forward for a quick reply

regards
