Re: Honda Unicorn Dazzler

At my bike the idle rpm is near ~1200/1250 when engine is hot(after some ride) and comes down to ~1000
I think that's normal.
May be needs to do something with your carburetor settings. (I am no expert )

Re: Honda Unicorn Dazzler

Get your carb tunes. Currently, its set to a lean mix. Visit the SVC/neighborhood mech and it'll be done in 5 min flat!

Re: Honda Unicorn Dazzler

I am not using my bike regularly now days, may be once a week or two weeks (driving more due to winters in delhi).
Which results in cold start problem even when the battery is fully charged. (I open the battery terminals before covering my bike ),
At times it proves to be a herculean task to push start it. (I have tried 3rd gear 8km clutch release trick, works well if you are riding daily but not after long gaps)
Once I had to push my bike all the way to Honda service center and I learned a new trick (for me), they put my bike on center stand , put it in 5th gear, pulled the choke and rotated the rear wheel. And it worked well.

So far with my experience of >1.5 years with this machine, I liked it, Its like wine (I don't drink ). When I am not riding it I do think of replacing it with higher cc ones, but once I ride it all those thoughts vanishes. I love the nature of this engine (relatively eager/one can rip it without any problem and it will still be smooth), its riding position is also not a problem with me, I found its high speed stability better than relatively heavier bikes (like hunk), the looks grow with time ( I even prefer it over FZs, dazzler's semi fairing and leaner aerodynamic tank gives clues of a tourer to me complimented by matching mid/high end power) and one can always enjoy the exclusivity factor. (not many know if any such bike ever came to market ) plus a consistent FE figure of (50 -55)/kml

If it was with FI and DC electricals I would have planed to keep it for ever.
Waiting for better range of products in 250 -400cc in our markets till then this will be my ride.

Re: Honda Unicorn Dazzler




I guess the recommended idle RPM should be 1400 +/- 100 (when engine is hot)
Try sticking to that and see if it works.

Re: Honda Unicorn Dazzler


I think there is tight inlet valve .which can cause unstable idleing.
Or vacume leakage between carb & head.
How can I check vacuum leakage.

Re: Honda Unicorn Dazzler

can a 4 Valve setup for Dazzler is possible.with some moderate modifications
as 4 valve setup is smooth for acceleration.

Re: Honda Unicorn Dazzler

How do you know your battery is fully charged? If the battery is fully charged, and you have a starting problem, then you should suspect the starter motor or the relay. If you are not using the bike for weeks, then your battery is not getting charged, and most probably your battery would be dead soon.

Test the battery voltage in the morning, and then test the voltage at idling and at higher rpms. If the battery voltage is above 13 in the morning, then your bike should start with electric start (you should use choke for cold engine).


Idle rpm should be at 1400 when the engine is warm. Set it at 1400 or 1500 when the engine is warm, and this way the idle rpm stays at 1000 to 1100 rpm when the engine is cold. Engine dies when the rpm goes below 1000 rpm.

Re: Honda Unicorn Dazzler

Ravi, Agree that in morning it will not be fully charged after this much gap. (I do use my multimeter to test it). And when its not charged the display goes blank and there is noticeable fluctuation in the neutral indicator. I always use choke to start it in morning, and I have to use it even in evening . (8.30 hrs later the non stop morning ride of ~25Km to my workplace).

PS: I replaced my stock battery last week as it was not getting charged (even after ~50ks round trip daily). Don't know if it was wise, I still went with stock specifications.
Exide again (XPTZ5) for INR 1350, but it has kept me away from this problem for now.

Also thinking of implementing a charging ckt for it, Who knows might come handy some day.

@pratik261
Yes the manual says exactly 1400.
but It vibrates too much on idling so I keep it a bit lower.
Didn't observe any problem till now.

Re: Honda Unicorn Dazzler


If my carb is set to lean mixture, why my bike return bad FE (43KMPL) But good pickup.
I also think my carb has to retune for good FE, but hiw I tune it properly.
I tried it from local mechanic & honda ASC but all waist. They say a 150cc bike will return max of 40kmpl then what u want .
Honda ASC style of setting the AFR mixture is simple open the afr screw to 1.75 rotation in engine stop condition.

Please buddy . Help me retune my carburettor.

Re: Honda Unicorn Dazzler

I face this problem of the bike waving left and right after hitting a pothole (mumbai roads), was reading the intial few pages and people had the same problem and solution mentiones was changing the cone set.
My question is what is a cone set??? I googled but I could not get an answer to my question
Can somebody explain/answer my question ??

Re: Honda Unicorn Dazzler

^ +1 to that, even I want to know.

Also, how should I know whether there is a problem in front forks or cone set?
I haven't changed my bike's fork oil or cone set till now (more than 23k kms). But lately the front suspension crashes over potholes, not bottoming mind you, just a 'thud' like sound. It also has become a lot harder, I mean I can feel every small bump on the road.
There is no oil leak from the forks, so I guess it is related to cone set, is it?

Re: Honda Unicorn Dazzler

Balls in the steering bearings are getting misaligned when you hit a pothole. Solution for this is to change the bearings (also called cone set). This snake-like movement goes away once you hit brakes considerably or you stop the bike.

Pratik, its time you replace the fork oil and the fork cone set.

Remember, when you go into potholes or speedbrakers, the front suspension should be free. Generally, when we see pothole or speedbraker, we apply brakes and keep it that way till we hit the pothole or speedbraker. When we apply brakes, the suspension contracts and when you go into pothole/speedbraker in this condition, the suspension will not have any play to act as cushion. We need to leave the brakes and allow the suspension to come up before hitting the pothole. This way, the suspension will have play to cushion.

Re: Honda Unicorn Dazzler

AFR at 1.75 full turns is optimal for Unicorn/Dazzler. First set your AFR at 1.5 turns and ride for sometime and see. Each time, turn the AFR upwards of 0.1 turn and check how the engine is responding. Settle at where the engine feels smooth and responsive.

Set the idle at 1400 rpm when the engine is hot; do not set it at 1100 which is low.

FE depends on so many things like, riding style, riding conditions, quality and quantity of petrol, clutch adjustment, chain condition, good engine oil, tire pressure, rider weight, pillion, etc. First you need to rule out all the above before concluding that tuning is the cause of poor FE. First, make sure the quantity and quality of fuel that you fill is right; change in quantity and quality of fuel would drastically affect the FE. Riding in 1st and 2nd gears would give very very less FE (in city traffic). Abrupt acceleration reduces FE. Poorly adjusted clutch also affects the FE. Underinflated tires give poor FE (Dazzler has tubelss tires which are prone to micro punctures and loss of air over days; you need to check air every two days).

Re: Honda Unicorn Dazzler

For re-tuning of CV carburettor especially Keihin carburettor check my signature. It is the factory method of tuning.

Re: Honda Unicorn Dazzler

I did show it to a couple of local mechanics, both said fork oil only needs to be changed if it leaks or suspension starts bottoming, hence ignored it. But now I will definitely get it changed.
By the way, manual doesn't mention anything about fork oil. If I am not wrong it is 175ml in each fork, right? Should I be worried about it's grade?


+100 to this.
I fact, I follow this same technique for both my bike and car, and its very effective.
