Hello everyone...I just got my first servicing done yesterday and started using my bike in full fledge....however while taking it to college, i need 40 minutes to just cross 6 km...the traffic jam made my bike extremely hot(I think) and then suddenly, I noticed that the rpm meter was showing 2.5 even at idle mode at a signal on the road.whereas normally it is just 1.5 ...is it a cause of concern?plz help

Topic Approved.
Started using the bike "full fledge" after first service? First service is around 500 kms. I don't think you should rev your bike this hard, within 500 kms only. Let it run upto 2000 kms atleast. Follow what your manual says.
Idle rpm being raised after riding for an extended period is a normal thing. But it should not go upto 2.5 krpm. It usually stays within 2 krpm. So:
1. See & hear carefully, if the idle rpm is flickering up and down. Just start the bike & idle it without accelerator. It should idle smoothly with no extra movements in the tachometer.
2. Ask the mechanics if they have fiddled with the carb in any way like idle rpm switch, AFR screw, etc. This step might go useless though.---

while i failed to understand the relationship between the term "started to use my bike full fledged" and samarth's interpretation that it means "revving the bike this hard", i want to know what is an "idle rpm switch", is it the "idle screw" or something else..??Comment

Re: Help need for rpm problem pulsar 200 ns
Fluctuating RPM can be caused by -Originally posted by Animesh Chatterjee View Post
very old/dirty spark plug
dirty air filer
Air/Fuel mixture of carb set to leaner side
leackage in pipe between carb and airfilterComment

Re: Help need for rpm problem pulsar 200 ns
I too was facing this issue with my ZMA since last few days. The idle RPM used to shoot upto 2.5-3K like the throttle is stuck or something.
Mechanic decreased the idling a little and cleaned the spark plug, although it was just 400kms old but still pretty dirty.
BUT I am yet to ride her for a good distance after that to see if the above worked!

Re: Help need for rpm problem pulsar 200 ns
Losen the idling screw and set the idling at 1350 - 1450 rpm and there you have it.
It worked fine for me. After this little tweak, it was more mileage and performance for me.
Thank you.
Ride safe.Comment

AFR screw should be rotated clockwise for lean. Turn the screw half a rotation and check if the same thing happens again. If yes, do it again. Oh also, while you make it a little lean, the idle rpm will drop a bit so keep setting it to 1.5k rpm. And careful, don't make it too lean. I don't think I should stress on the effects of a lean condition in the long run.Originally posted by Rakesh Rok View Post@Aditya N Bharadwaj, mate you had the same problem right. . ?

Just a word of caution- if you are not too familiar with these things, I would not suggest to fiddle with afr screw yourself.

Re: Help need for rpm problem pulsar 200 ns
i had all this prob initially and prob was solved easily by carb tuning. Now my bike is around 1.5 yearsComment

Check the spark plug, looks like the bike is running rich. Check the air filter too, it might be clogged.I am back!

Re: Help need for rpm problem pulsar 200 ns
This picture is wrong, you have to turn the screw clockwise to lean and counterclockwise to enrich the fuel mixture. Somebody take a good colored photo of 200NS carb screws, I will edit and post it showing the correct directions. The old picture circulating around is causing a lot of confusion.Originally posted by Aniket6626 View PostI am back!

Re: Help need for rpm problem pulsar 200 ns
SatSon gave good advice.
PS. don't adjust things on the carb if you dont understand it.......
Sounds like u have a vacuum leak or your AFR is to lean.
The tech shouldn't have fiddled with the carb anyway, but adjusting your AFR on a cold engin will give lean symptoms when hot.
When you blip the throttle does the take long to come down to normal?Comment

Re: Help need for rpm problem pulsar 200 ns
Hello BroOriginally posted by Aditya N Bharadwaj View Post
my pulsar is having the same problem where the rpm fluctuates from 1.5 k to 3 k
how should I make a mechanic understand the mention solution above - most of the mechanics are not that technical?
another option is can u make a youtube video how to solve this problem.Comment
