Warm up your bike, drive for 10 to 15 min, after that rotate the rpm screw clockwise to increase the rpm to 2.5k den open the throttle up to 4k and keep it there for a while.
Now when thats done turn the Air/Fuel screw to 1 and half anti-clockwise from full closed position.
Once again open up the throttle for a while and take it upto 5-6k rpm and turn the rpm screw anti-clockwise to decrease the rpm and set it to 1.4k

And now the idling should be stable and the throttle should be crispy. But the most imp thing is that when you close the throttle the rpm should some down quick.

buddy i hav done that on mine bike too but the rpm is not stable dont know why going up little bit then going down little bit not constant

Tuning SHOULD NEVER be done by counting the number of turns

This measure can be different or rather should say IS different for each and every carb and bike. Optimal tuning can be achieved only when the strokes become uniform and consistent. Also, its not recommended to be done unless you're not experienced. I never recommend fiddling with carb until you have some experience about it. Go to some good mechanic (prefer SVC) and ask them to tune your bike. Just make sure they do it when the engine is warm.

okay thanks my odo is 2105 now time for due service i will say them for tuning also should i ask for oil change or not i mean brand change??

Try your luck

If they allow you, go for Shell Advanced Mineral oil (AX5 I think). Shell suits quite well to RTRs.

Unless we practice how can we gain experience? I'm of the opinion that if you are ready for a lengthy trial and error process, you can do it yourself. First understand well the symptoms of both rich and lean mixtures, get a couple of spark plugs, tune it, test it...

Well, this is what I had planned, but is yet to do

hi buddy, is the overheating is due to lean or rich mixture??

Hi frns, my bike is A180 1600 on odo. the problem is that whenever i rev the bike above 6k rpm needle stuck at 2000 rpm than slowly comes down to 1100 rpm, is it tps or some other things...

This is a common problem among new RTR's it is the throttle cable...Did you experience it only now or from the day you bought it..? Tell the ASC about it..

hey mate, by servicing do u mean the regular oil and filter change, chain lubing etc or some other work that u did?
it would be really nice if u could elaborate a bit more on it!

and regarding engine oil, i am myself using motul 15W50 semi synthetic oil.
it has made the engine smoother, doesn't heat up quickly too!
but it has robbed the engine of its revvability.engine feels lazy now

i would be soon changing to a 10W40 grade semi synth oil soon!

Hey, it is a regular servicing. But I have changed my oil, air-filter, disc-pads(F&R) with oil, Oil-filter, Spark-Plug(fitted NGK). Then I had changed tap-heads from one of my friend(whos a auto-engineer & a mechanic). Rear Shoe-hub.
While Changing my Tap-heads, Engine was cleaned from within( not full cleaning).
Now next time I change my disc-pad oil, I will be changing it from DOT3 - DOT4/ DOT5.1..
This time I will be changing my chain & sprocket as the chain has become super loose.
I checked it out that using 15W-50 or 10W40 makes a lot of difference, but I will be preferring 15W-50 as it is better than 20W-50(which currently i am using), not only in winters but also good for long rides. 10W-40 is just for winters(morning starts).

Now you tell me what all is left to do??

Actually both too lean and too Rich mixtures will cause overheating.But it is most noticeable with lean mixture.RPM stuck & high rev power loss is a classic example of a too lean mixture.When you have a perfect stoichometric mixture then the engine produces a perfect sound.too lean and it produces a high pitched sound,too rich and it produces a deep sound.

this happened sometime after first service, yeah i've told to asc they did some tunning but problem persist and after few days went to asc they clean the carb but the problem is still there, recently i check the plug its ash color my carb tuning is 2.30 from close position and yeah i tried uphill with pilion 1st gear engine struggle a lot just like my previous bike honda stunner..

Next time you go to SVC, ask them to set the CO level of you bike. They have a digital instrument like the pollution check guys have and set the CO level of the bike in real time with the help of the instrument and tune the A/F ratio of the bike according to required level.

This should fix the problem of improper A/F and hence your problem.
If donot have a similar instrument in your SVC check in from a different TVS SVC.

Your running lean... Do this when your engine is hot..
1.increase your idling to 3k or 4k rpm
2.turn the fuel screw all the way in this would lean out the mixture further and you should see your engine speed decreasing.. rather hear it
3.Now slowly turn the fuel screw out slowly step wise and there would be a point when your engine speed would increase keep turning it out this would make your engine run rich.
4.At a certain point your engine rpm would decrease when your turning the fuel screw out.Stop at this point.
5.Now decrease the rpm to the desired level.
