What have you done to the machine in the time before you noticed this problem? It could be that your clutch friction plates are worn. This would give you the same problems, it may also be a badly adjusted clutch cable. You need to make sure the clutch lever(handlebar) moves at least 3/4 inch at the end of the lever, before it bites or releases.

My zmr is in big vibration. plz solv my prob.. wht i do...?

may be connected meter chain has broken,take a visit of mechanic he will fix that problem

Check from drainplug or any packing in the engine? You have to be more specific

That seems a big job, did he say how much he will charge to do it?I think, unless you are an engineer you will need a manual to do a job like that, although you may find one somewhere on the Internet, if I were to attempt that I would prefer to have a paper one, I could refer to as I went along.

Have you got a fuel tap petcock? If so, just turn the fuel off after each run. If you've got a diaphragm (vaccuum) fuel tap, then maybe the diaphragm has perished.

sounds like u mite want to bring it to the shop

the most important is you should have a good oil filter if you have not change oil and you,ve gone pass time.

hiyai would suggest the spark plug is either dirty or failing remove it and check the spark by placing the plug on the engine touching a metal part and stat the bike there should be a nie fat spark if there isnt replace the plug and give the carb a clean out it might not be the problem but it wont hurt to do some servicing Hope this helpsJohn

Hi,Check the wheel bearings and release the brake cable, just to make sure if it still stuck.

this is not a complint. Only cold starting problem. Either you warm up the engine by closing the choke lever half and opening the throttle slightly or try with closing the piolet screw half turns, in this case you get less milage for your bike.

Hi, the symptoms you describe, sound like mechanical, poss partial sezure, i presume the oil level is up to the mark as required, if the problem is mechancal i would suggest you do not ride this machine until the fault Has been rectified, seriouse dammage may occure to the engine and rider ask for a profesional oppinion, take it to a shop, for a fee you will know for sure what the fault is

Hi, My dear friend pulsar220 has more powerful brakes but its a bit risky.as it has dual disc brakes and the bike sticks as soon as you press both the brakes while in karizma there is a disc brake and a drum brake so its kinda more safer than pulsar220.For more information go to the link below.

This is due to the fact that the engine is not igniting and so the fuel excess leads to the flooding within the cylinder. Now remove the spark plug and manually pump out by starting the engine. Hold a piece of hard cloth on the mouth of the spark plug thread and crank. You hear the air pressured out with the flooded fuel. Now check the spark plug gap and the spark intensity. if bad replace the plugs.
Finally check the fuel /air settings on the carburater, this must be tuned properly.Finally check the fuel filter for clogging.

Hi,
That is normal for a small air cooled engine to help it warm up easily.
The minimum operation of your engine requires a certain warm temperature to fully sustain its full efficiency.
Hope that clears everything.
Thanks for using FixYa!

The mixture screw has its main effect at idle.It is called the idle mixture screw. So may not help fuel consumption a lot.

To adjust it.
turn it in until it stops and count the number of turns exactly(so you can put it back if adjusting doesnt work)
Then screw it back out to the original position, and start the bike.
If you screw it out about half a turn, from the original position, the revs should rise and then become uneven, with the revs rising and falling(this is lean)
If you screw it in half a turn from the original setting, the revs should slow down and maybe stall the engine(rich)
Pick a place in between the two, where the idle is smoothest.

Of course make sure the bike is serviced first, clean or new air filter, new plug, new oil, adjust valve clearances(if it has valves) check tyre pressures, adjust chain (or replace if old)
The new air filter may make the biggest difference, as it gets dirty or old,it will richen the mixture right through the rev range.
And fix the shift key on your keyboard please.

sounds like the fuel is faulty,replace it and you might be lucky.
