Did you run some Fuel System Cleaner?

Is the air filter clean?

Valves adjusted?

New plug?

Chances are it's nothing serious, but a combination of a few things than need maintenance.

It seems like you're making a lot of new posts with lots of issues with your bike, many of which are one and the same. If mechanically inclined, I would invest in a shop manual and educate yourself highly on your bike; after all, it is all that's between you and the pavement.

In the idea of safety, sometimes if that's not the road you want to go down, it's better to let a shop figure it out and repair it for you.
jsonder, jkv357 and MotoMike like this.

Tis better to be thought a fool and remain silent, than to open one's mouth and remove all doubt.

i had told the service centre guys to fix all issues you find,they just fix the shim issue,thats all.
reason for many problem is this bike had only clocked 26000km in 5 years.iam searching for a good mechanic who can fix all,not going to service centre any more.

Getting your bike to a competent motorcycle mechanic who can diagnose the issue(s) you're having is key.

And as cbrlocal suggested, get yourself a copy of the factory service manual. These are complex bikes, and even the most experienced mechanics would be at a loss in their ability to diagnose problems without a service manual at hand.

What does the inside of the tank look like?

You may have rust inside that's restricting the fuel flow by clogging the filter or damaging the pump.

If there is a significant amount of condensation in the tank it will sit at the bottom and occasionally get picked up, causing odd intermittent running problems.

I would suggest taking a good look at the tank and draining all the gas.

Pull the plug and post a photo of it.
