Guys i know R15 is not so powerful like other commuters in low end but it really rocks at mid and high end ! My bike is v2.0 and I'm afraid that my bike is suffering from some unusual problem !! it struggles a little in doubles while i shift up to 2nd gear from 1st gear !! Please help me in sorting out this problem !!! And also there is a screeching noise from the rear disc while i brake I've heard this sound from my friends hunk also ! What is the cause for this problem ?

Vehicle profile :

Make : Yamaha R15 v2.0 (2011)
ODO reading : 600 kms

I think your shifting to 2nd gear lil early . When ever you ride with pillion try to shift up @ 5-6k . And for screeching noise - Go to SVC and ask them to clean Disk pads and disk

Dinesh'Jee , what fuel are you using now ? Fill fuel tank with IOCL Xtra-premium or BPCL speed / speed 97 petrol from a known reliable pump and tell us if the knocking problem persists .
For noisy brakes go to yamaha service and have the brake cleaned & serviced .

What knocking problem? You have not clearly mentioned whether the knocking occurs when you give accelerator while in neutral gear? If not then you need to change your riding style.

I used to refill at Bharath or Indian bunks !! The problem is only @ 2nd gear . As its new i was advised to shift up swiftly and to maintain my rpm below 5 for first 500kms. So i used to shift up to 2nd gear at around 3 or so . i din accelerate much while shifting up. I found the problem vanishing when i shift up after a good acceleration to rpm 5 & above ! This is my problem ! It persists even when it is driven without a pillion rider ! Should i shift it above 5 always ???

To mention clearly it is a sound that you can hear from your engine when you try to drive your bike at low speed like 20 or 30 kms/hr in 5th gear & above ! Your engine ll be struggling and vibrating to pull the load ! This is what i hear when i shift up to second gear at rpm 3 ! And i don hear it in neutral .

So, it is your riding style which is BAD. Yes, 20-30kmph in 5th gear is surely a killing. Use required gears at speeds.

Its neither the fuel nor the bike at fault. You need to adapt to a different riding style with this bike. You are actually lugging the engine by shifting at <=3k rpm with a pillion on board. Move your shift points slightly higher to around 5k and all will be good. Regarding the brakes, just get hold of a good brake cleaner and you will be at peace.

Above advice is for real knocking issues. But see below for his issue:

This is not what is called as engine knocking!
Your bike is fine..just get used to the gearing and engine characteristics
