    Check the spark plug tip color.Lean AFR will make the engine overall hot.

    • Seems like there's not a single proper review in the Whole hunk thread.

      Only discussion engine oil and some mileage.

        1. Sudden loss of compression with Kicker going very free for 5 or 6 kicks and then recovering to become absolutely normal...
        Keep a check on the quality of petrol used..and try not to fill in bunks on the highway...the bad petrol forms varnish on the valve stems which leads to sticky valves.
        2. Bike starts and idle but cannot accelerate, and if accelerated ,will switch off.
        Loose contact in the CDI unit Connector is the reason..This happens more in the wet season....Best to disconnect the connector from the CDI unit and spray WD40 into the connector and re connect...This will keep the moisture away and less loose contact problem.
        3. Bike will suddenly loose it's ability to accelerate...typically after a stop over after riding some distance, Revs on top gear will be 4 to 5 k only...
        This is because of throttle slide getting stuck to the carburetor body...reason is because of the slide coating coming off and getting wedged between throttle slide and carb body....probably due to bad petrol causing deterioration of the coating...remedy with the help of a good knowledgeable mechanic GENTLY remove the coating off the slide with Zero Emery abrasive and reassemble properly.
        Try to exhaust the petrol in tank within 20 days of filling .Do not park bike without use for more than 2 weeks at a time.
        i have been living with this problem since the last 2 years... the bike shuts down for no reason and later starts again (for no aparent reason of rectification)

        the symptoms have been exactly as mentioned above... i suspected a cdi unit failure and had also got a new one installed temporarily (contacts in service center). but the problem was not resolved...
        i had installed a ucal bs-30 carb on my bike as part oof modifications and the problem stopped (actually, i have not faced the shutdown problem since last november). maybe my carb was defective...

        I was preparing myself to part with the bike... guess the carb is all i have to part with...

        thanks buddy, real thanks.

          Glad to be of help....since you had changed the CDI and checked, and the problem still occurs, I suspect that the Valves are getting stuck at random...Elsewhere another owner had reported this also due to loose contact in the Ignition switch..though it had occurred rarely, one has to keep this also in the check list to be sure.

            Let me chec the milage again.
            am i need to unplug the sparkplug and post the picture of spark plug here?

              Yes if you can,We can read the plug ans say whether we need to make it more richer or leaner.

              • White Smoke

                Greetings. In my 2300 mileage ride i did twice pull the throttle and pulled it to 8k rpm in every shifting. And twice i saw a large amount of white smoke coming out of my exhaust.
                Guys, is this anything to worry about?

                  Yes it means you are burning Engine oil..First CHECK YOUR PRESENT OIL LEVEL,and top up before riding.

                    Thanks. First thing i did was checking the oil level and level is ok. Using HH 10w30. 300 k.m. till last change. Both occurrence happened in this oil term.

                        What should i do now? Should i change the oil?

                          It is not just the oil issue, since oil seem to slip past the Piston rings and burn in the chamber,suspect bore and piston wear. How many Kms on the ODO ? If it is past 35 to 40 K Kms mark , you may have to go for re-boring the engine...If the oil level is not decreasing in 2,000 Kms then suspect the valve Stem Seal leak
                          SVC can do a Compression check and tell you the problem..

                            Thanks psr sir. But SVC mechs are all laymen here. It's up to me who has to point the probable causes, then they'll check one by one. That's what i wanted to know the causes. It's a new bike, only 2350 km on the odo.

                              If your bike had done only 2,350 Kms this problem should not happen under any condition....There seem to be an engine or valve stem seal oil leak...If it is the engine problem ,then it is a serious issue ,and must be sorted by the SVC under warranty.
                              Check and post Pic of your spark plug here to diagnose the problem.Is the oil level going down ?

                                I'll upload the pics of my spark plug. The oil level is not going down. Smoke dose not come all the time. If i give it a rest for 2-3 hours then it comes at the beginning for 2-3 minutes. And when i pull the throttle.
