    Re: Honda Unicorn Dazzler

    You were spot on Sibun! It was indeed the choke thingy playing here. The mechanic immediately told me its the choke after inspecting my vehicle. He also said tappet adjustment needs to be done too as it was having a slight khad-khad sound when the engine becomes hot. Both issues fixed and bike is as smooth as butter now.

    I am having a wierd problem with my 3 year old Dazzler off late. The problem is with the engine idling. When the idling is set to around 1400 rpm, whenever I accelerate and let go the throttle, the rpm goes down slower than before and sometimes the idling gets stuck at 2500 rpm for a while and then goes down to 1400 rpm. And also sometimes the rpm doesn't go down beyond 2500 rpm unless you throttle it higher for two three times. This problem goes away if I set the idling to 1200 or 1100 rpm but then it results in frequent stallings. Can anybody throw some light on what could be the problem? I just want to be aware of the root cause before taking it for service.
    Its the choke cable that is playing havoc. Just change the choke cable and also open the choke piston and if rusted change it. Change the cable and choke piston as a set and your problem will go. The problem what you have mentioned is know as dieseling. Due to excess fuel due to choke remaining open the engine runs like diesel engine firing due to heat. Just change the choke cable and choke piston set. All your problem will vanish and engine will idle at 1000 rpm beautifully.

    Any good mechanic or service center for Honda Dazzler servicing in Bangalore?
    I am really fed up with the Silicon Honda service.
    Check : [MENTION=51754]theironhorse99[/MENTION] managed to stay in service-center during servicing.
    Honda CBR 250R - Page 1447

    Try that couple of times & see if it makes any difference in service provided.

    To sum up what everybody said:

    Carburetor (most likely candidate):
    1. Carburetor cleaning : Jet's air, fuel & air-fuel mixture passages (inlets/outlets)
    2. Carburetor mounting clamps for Vacuum leaks

    Spark Plug:
    Service age, condition & need for replacement.

    TPS:
    Check TPS readings are within recommended range between 0-throttle & full-throttle.

    Throttle Cable:
    Free movement/return of throttle cable @carburetor end.

    Air Filter:
    Service age, condition & need for replacement.

    First check if the accelerator cable is sticking somewhere. Replace it if its too old. Second, check if there is any vacuum leak in carb. Tune the carb properly.

    By any means, have you pressure washed your bike lately? If so, there are chances of water seeping on to the Spark Plug Cap which will affect the current frequency to the plug.

    Cheerz!!
    Thanks, will check that. My bike is hardly used though, just 4500kms on odo. Yes, pressure wash was done around 20 days ago.

    I think that the AFR screw was adjusted before when the engine was not at its optimal working temperature.
    This started happening all of a sudden. AFR screw was never touched, in fact I don't even know where it is.

    Whenever you grease or change race bearing set let the cone settle down, it's just like taking care of a newly assembled engine, if you wash it instantly after gettin new cone set the water could seep into the newly filled grease and hence make it unaffective, just let the balls in the cone set make there own way, and if you wanna wash your bike even after sometime never point water hose directly towards con set.

    I too faced this problem got the bearings changed known as coneset its good after that(1000 plus kms since i changed the bearing).It usually happens when the bike hits a pothole or a rough road i just stop at the side of the road wait for a few seconds and continue again but its not the solution just a temporary thing one can do
