I think it's the ignition coil as the bike starts after some time again. Happened to one of my friend's old Pulsar 150.

Yes, i still have 2 year manufacturer warranty along with additional 5 Year extended warranty.. . But the problem is HH service center guys here in HYD are so worst and arrogant that while the vehicle is in free SVC, they dont even look about the complaints.
If you still insist on any complaint, then they tell you that some part needs to be replaced. But they never try to figure out how they can solve the problem

Shoot an email [be firm and not rude] to Hero and describe your problem and the 'attitude' of the service center. This may help you.
Or contact @shoeb2015 .. he owns a Hero Extreme and maybe able to guide to a helpful service center.

to rule out fuel blockage at the tank area, do this:
Pull out the petrol pipe from the carb end and keep the petrol tap in the ON position and see if you are able to drain the fuel in to an empty bottle.
Again try this step with the fuel knob in the RES position.
You should see a steady flow of Fuel and not droplets.

Bike Details:
Hero Honda Karizma R
Mfg Date : July 2012.
Kms clocked till now : 13,100+


Now coming to my problem is, Air Lock ( Please don't say its a common problem ,because i have gone through the whole forum regarding this and i have tried all sorts of workarounds , like opening fuel lid, blowing air through it. But none of them helped me

First, there should be a small hole on fuel tank cap for allowing air/vacuum to escape out. If this is clogged the air/vacuum from the fuel will not escape out. Clean it. This is a simple DIY job.
Second, you need to open up the carb and check for stuck diaphram and worn out needle. Blowing compressed air into all holes in the carb and allowing petrol to flow through it should clear possible air locks inside carb. Get this done at a local mechanic.

Finally, if the issue still persists after the above workaround, it sure could be a faulty CDI (AMI). This cannot happen unless the bike has been exposed to abundant water splashing on it. The ignition coil will not give up so quickly.

Keep us posted!

@TS- First of all if you have the old spark plug then replace that and see if problem is solved. New spark plug means not always good as sometimes fakes are also there and i have seen that in service center and also sometimes new plugs are also faulty as in manufacturing defect.

I can't comprehend why they changed the spark plug if it was working good. After changing the plug, open the float bowl of carburettor, no need to open complete carb, and clean the jets. Check the contents of float bowl. Is there water in float bowl. If there is water that means tank has water. So clean the tank by dismantling completely as blowing it dry with vacumn cleaner and also by putting a cotton cloth inside it and wiping it dry. Be sure to remove the petrol tap to drain all the contents and also remove the float assembly as it will help in inserting cotton and wiping the tank dry.

Do the tank cleaning only if water is there in float bowl. Otherwise just open the tap and see if dirt is there on petrol tank filter. But first fit the old plug and see if problem is gone.

I have faced this problem in a new genuine plug which got solved when i switched to old plug.

The same happened to my ZMR when it was new.. the wire to the ignition coil was not connected properly and it was loose.. i had to find out myself as the ASC guys never bothered to listen to my words..

[MENTION=28527]sibun[/MENTION] May be you are right, because with the old spark plug i have never faced this problem. But sad thing is i didnt take the older one and left it in HH ASC itself...

Guys,

Yesterday a local mechanic examined my bike and said as im using HP (Hindustan petroleum) petrol regularly could have caused the problem.

As HP petrol has higher carbon in it and its getting clogged to the head of cylinder. and that's why the valves of the engine are also not properly functioning....

In this case, go for a normal NGK spark plug. Will hardly cost you some 100/-

are you filling up fuel from HP?? and no.. i never faced such issue and I usually fill up fuel only from HP and BP.. Indian Oil are culprits and caught them a number of times trying to cheat me.. so I stopped filling fuel from them unless and until I am running out of fuel

Not even that much, 65 rupees only! Better to go in for a G Power though.

That mechanic is taking you for a ride, don't listen to him. A ZMA won't require valve job and decarb so early even if bad fuel is used.
My suspicion is even more on the ignition coil as you said you did not face any problem with the earlier plug. Maybe your mechanic/you did not connect the cables properly while installing the new plug. As I said, check the ignition coil. Somebody post a picture of ZMA R ignition coil installed on the bike so OP can check for himself.

Just get the air fuel mixture setting right, this can be done by moving the screw around carb, a good knowledgebale mech should be able to do this

Re: HH Karizma R . air lock problem. ( Please take time to read my thread)

I used to face the airlock problem for Pulsar and many a mechanic tried to take me for a ride, till one guy told to look out for a gradient freewheel and put the bike in gear - and this trick never failed.
