Considering the manual does not even venture or talk about touching those screws, I'd be careful meddling with them.

Check for any vacuum leaks along the air intake and related plumbing.

Here is a video about adjusting a similar screw on a Himalayan.

I am taking it to the service center once again.

Here's a video for your reference of the issue.

Did you wash your bike recently ? If yes, open the fuel cap and see if the rubber bush is cracked. If the bush is cracked water may have seeped in and that may have fowled up the fueling.

Had a conversation with RE dealer, who again informed that RE is relaunching the twins again preferably in March. As per them next update on the way is navigation and price increase.
Hoping there are alloys somewhere.

Here's an update. The SC people cleaned the throttle body as they couldn't figure anything else out. Now the bike is starting fine but a lot of misfires and really unstable rpm.
Now they have told me that they'll replace the throttle body and have ordered the part.

When you say 'they couldn't figure anything else', what other things were they checking out ? Were they focussing only on the throttle body alone or did they check for any anomalies in the fueling and ignition departments as well ?

Honestly speaking, ordering a replacement part without knowing the root cause sounds like a wasteful excercise for me.

Yeah I agree. They had no clue what they were doing, I was there from 11am to 5pm. They cleaned all the connectors and then cleaned the throttle body, but no one in the SC has any clue as to what might be wrong.
I am going again to get this unstable rpm and misfiring issue checked out and spend my Sunday with them

[corvus corax]

Good thing that you are supervising the job. While you are at it check the spark plug caps and lead wires for any loose connection and corrosion. Have the spark plugs pulled out and see if they are fouled or contaminated. Get the secondary air injection circuit checked as well. I hope they zeroed in on the throttle body after going through all these.
By the way, have you checked if the tank cap rubber seal is intact?

Has anyone tried disabling one cylinder of the bike? Is it like even possible? For like city needs one cylinder of 300cc would be more than enough and when you need more power the other cylinder can be activated again.

Why would you want to do this? The bike was not designed to run on one cylinder. You are likely to damage the engine by doing something like this.

Could you give us some history of the problem and tell us a little bit more about your bike?

• How old is your bike?
• How much has it run?
• When did this problem start?
• Did this problem surface out of the blue or after a certain activity such as a wash or service?
• Does the bike misfire when you ride?
• Checked for water in fuel?
• Smoke from the exhaust?

1) 2 years
2) 5k kms
3) last year's November approx
4) out of the blue, no wash or anything near the time it appeared
5)it misfire a little when below 2k rpm and using engine breaking, not while accelerating
6) how do I check for water in the fuel? I recently topped the fuel again as the tank was almost empty
7) no smoke from exhaust

I had tried once to run the bike's engine on one cylinder by unplugging one of the spark plugs. The engine continued to idle albeit on a lower RPM. When I gave it the throttle the unplugged cylinder popped and sputtered.
So, no. You can not deactivate one of the cylinders in this bike. As bhpian sandeepmohan pointed out, the bike was not designed for it.

[arpanjha]

Disabling one cylinder by disconnecting the spark plug is a risky thing to do. As per my knowledge, just removing or disconnecting a plug will not disable the cylinder, rather increase a dead load on the engine, the physical parts, the piston, additional crank load remains the same and they keep moving. Just the generation of power through the cycle doesn’t happen and puts additional strain over the engine which now produces half the power and got additional dead load to move.

[daretodream]

Well I guess some high end cars like Audi have cylinder deactivation technology for fuel efficiency. So, it might be working in an automated way be stopping fuel injection and disconnecting power supply to spark plug or glow plug.

Not sure when they are relaunching but price hike already happened, without any changes.
