[Resolved]  Hero Honda CBZ Xtreme — Clutch & Gear Rod

I have purchased a CBZ Extreme in the month of July. from the day one i am facing one or the other problem.
initially i had problem with nuetral gear, showroom people said its a problem with gear rod and replaced it in warranty.
next service i have complianed to them about slow pickup and this time they said its an clutch plates issue and replaced them and charged me for the same.
and once again i am getting noise from chain when i cross 60KMPH.
can anyone suggest me whether clutchplates would have problem with in time span of 3-4k kms usage and also i would like to know whether gearrod has anything to do with clutchplates
