    Default Honda unicorn 160cc

    I have a honda unicorn 160cc bike, bike suddenly stops sometime while slowing down on speed brakers or some bends, then it never starts again, the kicker goes freely and unable to start the bike. (10 minutes frequent kicking with full throttle release makes the bikes start)
    This problem repeated almost four times, this problem started in my new bike since 4000km.
    Honda service center does my bike service and I service my bike every 4000km.
    Engine oil is changed, air filter, spark plug changed as per schedule as advised by service center.
    As per Honda service center, they told it is some problem with Valve clearance.
    They have adjusted the valve clearance but the problem looks like repeating again.
    I checked with Mechanic outside, they told it is petrol rich problem(They have started the bike with full throttle by cranking self start continuously).
    I am really worried of this problem. Could you please advise me what can I do to avoid this problem

    I am not an expert, but I had similar problems in my old pulsar 180 dtsi. The culprit was the fuel tank drain hole which used to get clogged easily thus creating a vacuum inside the fuel tank which didn't allow petrol to flow down the carb easily.

    It's just a wild guess, but you could check your fuel tank drain hole first. Tell any roadside mechanic to check whether it's clogged up or not, or do it yourself with a syringe.

    Hi ar.asin
    if this is a fuel tank breahing hole problem as said by arya. Then just open the fuel tank lid while you face this problem in the next time. Then you will be able to start the bike again. If it is starting with this method then clean the breathing hole with pressurised air. I had this same issue with my yamaha szr. And fixed using this method.

    But one of my friend had this same issue which was not related with fuel tank. His mechanic told him that, it was a stucked valve problem. Which is common in unicorn. So that you should not slow your suddenly without downshifting gears. Mechanic told him to push the bike in gears and check the kicker to ensure it is having the noramal preassure then start the bike for an immediate fix.

    Hi, ar.asin. I do have same problem with my unicorn 160. Even my mechanic told me that it is stucked valve problem. I face this issue 5 to 6 times in 3.5 years and my odo is 29k. Whenever it happens mechanic told me to push start bike in 3rd gear.

    I've no idea about kick getting stuck. I experienced only compression less kick starter problem.

    Nothing to worry, its a common problem in Unicorn 150 and 160.
    Usually occurs due to carburetor not tuned properly (Usually mechanic leans it to give maximum mileage, which is a bad practice)
    When bike runs in lean condition especially above 60kmph valves will burn off due to excessive heat caused due to lean condition.

    How to fix it?
    1. First and most importantly, get the tuning done properly (Usually the carburetor tuning is 2 full turns out from fully tight position of air screw)
    2. Need to reseat valves/replace valves depending on the damage. Usually only valve reseat is required, can cost around 300rs for reseat and 350rs for labour

    Honda has just screwed my life! Everyday i hear, new problems about 160cc honda engines, the whatsapp groups are also filled with problems in hornet . I have observed a thing, that people here in xbhp conceals the truth about Japanese brands and in whatsapp discussions it's another story! Because of all these reasons buyers like me, are facing problems.
