I had read on the internet that crank issues could be the result of non constant sound while idling. Could be the shaft or the bearing. If I am not wrong, you may be getting a few seconds of constant idling with a few coughs thrown in ? If yes, then I would keep you posted when I go in for the crank issue check on mine. If you get to a solution first please lemme know too.

All of the other issues like low pick up etc were taken care off by the advice by [MENTION=74543]krixna[/MENTION] but this one still is persisting.

Yeah exactly there are coughs between the constant sound but this thing goes away if I tune the bike without the CO machine(by just looking at the needle when it becomes the most stable). One more thing I have noticed that after tuning at CO the fuel supply at low revs is very low.

Bro, engines have been tuned for decades without any analyzer machine and they have run just as perfect. You should understand one thing. Tuning the engine by looking at an analyzer is for noobs who don't know to tune the engine without it. The actual method it to set the minimum Afr that gives your engine 2-3K rpm without fluctuations/hiccups.
Edit: another method is to set a very lean Afr, and opening it up half turn at a time and taking a short test ride after each setting till you are satisfied

Can you post a pic of the AFR screw?

Thanks bro, so should I try tuning it at home? If yes, the what's the exact method. I have read and tried things like setting the idling at 2-2.5k rpm and then turning the AFR screw clockwise or anticlockwise. Any perfect method other than the above stated one?

Here's one method:
**Warm the engine sufficiently before doing the tuning. A short ride of 2 km would do**

Close the Afr fully (0 turns).
**Do not tighten the screw, it will damage the carb. Just turn it clockwise till at one point it stops**
Now turn back (open) the screw to 4.0 turns (8 half turns). Start engine and set idle to 2500 rpm.
Now set the screw at 3.5 turns. Set speed back to 2500 if it increases.
Keep doing this (turning half turns inwards) till at one point the engine rpm *decreases or starts to fluctuate*. That is the point where the mixture goes lean. You need the half turn before this, ie, your previous position.
Set idle to 1500 rpm.
Take a test ride. If any small hiccup remains, open half turn more and set idle to 1500.

Just now tuned the bike and found 3 turns to be perfect and the missing fires are gone now it sounds constant haven't found any hiccups though will update you if I find the hiccups at any rpm. Thanks for the help mate.[emoji4]

So 2.5 must be where the missing starts. Anyways, check while riding, when the engine has warmed up. While cold, the hiccups may be there a bit, it's usual.

Yeah at 2.5 the rpm needle was fluctuating so i kept it 3. And yeah when the engine is cold slight hiccups are there. By the way what's your current carb tuning?

It will be different, since each carb and engine combination will be different, even if very small. Mine runs on 2.0 now, I have two friends, one runs on 2.0 and the other on 3.0. I tuned these myself

, same method as I told you.

Actually I am planning to replace the throttle cable to eliminate that slight sluggishness also. Was thinking to get the spark plugs checked or replaced(if needed).

Actually 2.5-3.0 works for many and 2.5 seemed to be the factory setting. I hope I remember well when I tried it.

Take a CO to confirm that you stick within the range

U r getting it wrong. Earlier for 3k km the ride was much smooth now its getting harsh , that doesn't means it was vibration free earlier or now . Gear shifting is not smooth , engine heats up quickly , these r the symptoms to change the oil .

same, gearbox gives a feel like jamming many times. Running 7100 for 1500 Km+ till now. Vibrations are at control, but still was expecting a bit more. Well, better than Bajaj stock however and yes it does differ from bike to bike

Because in Kolkata showrooms they are saying that it's booking & availability is closed for over a month.

I saw a similar trend recently. There are many rumors about 200NS FI+ABS (though spotted one) and some concrete info for now is CS400 might be brought to light in another few months. Perhaps earlier than BMWG310R. CS200 is also rumored.
