Big tyres

Hi all.new to this but I just got my new triple black Rene 1000 xxc and changed my tyres to 27-10-12 kenda executioners on all corners.however a clicking noise started after about 20 hours and now a squeaking noise when I jerk the trottle and when engine braking engages when slowing down,there is a loud whining noise while easing off trottle? Someone told me that the gearbox is geared only for stock wheels and that I may have fecked the box? Something about gear ratio or ratio of wheel turning?had these same tyres on my grizz 700 with no issues? Going back to dealer tomorrow to find issue but he said it prob is belt? Belt done at 20 hours? Please help!!! Mick.
