Hey Ravi you seem to have had an awesome experience with Dazzler and I really appreciate you sharing your experiences and knowledge with us.
Had a quick question-
I got 2nd servicing of my bike done today and it feels much smoother now!The only problem being the rear disc brake.It was working fine before servicing but its working very poorly now.The mechanic said that it would take a day or two for the disc pads to get dry as he washed the bike today and then the performance would improve.Is there any way for me to adjust/tighten the rear disc brake?

My dazzy's head light switch (the one on the right) is giving problems. Sometimes it doesn't turn off no matter how hard you try. I guess the switch is screwed. The garage guy said the whole switch assembly (including wires, as it's glued to the switch) needs to be changed as it's a combined part. He had done something and it's alright now, but he said it's just a temporary solution, the problem will return after a while.

Has anybody changed the head light switch? I need to know the approximate cost of the same.

The gear switch assembly will be approximately 500 to 600 rupees. If your bike is in warranty, ask them to replace it under warranty.

64kmpl???. That's amazing man. How much mileage you used to get before? i guess around 50-54??

What do you think is responsible for such a drastic change in mileage?
May be emotions/sentiments. Dazzler is trying to play all sorts of tricks asking you not to sell it.

Update on my bike: I am getting lot of vibrations in the bike. This happened after my previous service.i.e 23k service.
They adjusted tappet and everything but still some sort of vibration is there in the bike.
In this service also they could not arrest it. They told they will call their workshop manager to assess my bike. so i will be waiting for their call.
And also my RPM is not stable at all. In morning its around 1200 but after sometime it shoots to 1500rpm and sometimes even worse 1800-2000rpm making the bike very harsh and noisier.

I try to manually reduce it to 1200rpm again and in the morning again the rpm would go below 800rpm and bike cannot idle. so we need to increse it a little to make it idle.

hey guys,.....
iam new to this website
you can call me bhargav , i am doing my Engineering in Bangalore
my bike (CB Unicorn Dazzler) is 1.5 years old done about 15300Km,
i commute to my college daily in bike(60%city 40%highway)....!!!
i'll get the service done once in every 3000KM.......
by bike's mileage is around 42-43Kmpl..................
plz tell me ways to improve it
these are the things i do for my bike:
1: start using choke and leave it for 15sec every morning...
2: won't exceed 45Kmph(3500-4000RPM 5th gear) for the first 4 KMs
3: fill petrol only with trusted bunks.
4: check the air preasure every month.

I have to say this there is bit of breaking involved while iam travelling through the city......
and also can anyone tell me the best brand for engine oil

please help me out

Well just want to put in some numbers as stated in the manual.

Tyre pressures Front 25 Rear 29 without pillion and Front 25 Rear 33 with pillion. Best to stick to this and check pressures on cold tyres (run less than 2kms) since these are cold tyre pressure recommendation, check it every time you refuel or every week and after any long period of time when the bike has been left unused. Also store bike in shade as alternate heating and cooling of bike tyres when kept in open for long leads to the tyre rubber becoming brittle and cracking.

Spark Plug replacement: Every 9000kms
Air Filter replacement : Every 15000kms

Best to change both of these simultaneously at 10-11000kms. My spark plug at 10500 kms is still looking good, but I will probably change it at 11k along with air filter.

Spray chain lube every 500kms (literally 5 minutes job, one can of Yamalube cost me Rs250 and will last for more than 2 years at the rate I am using it) Do not ask service centre to do "chain overhaul" because that is bullshit and they charge Rs80/- for it and apply used engine oil. They don't even bother adjusting chain slack and the road grime sticks onto the sticky and gummy used engine oil and increases friction. For the first two days everything will seem smooth and as soon as excess used engine oil has flung off the chain, your troubles will start.

And finally, my mantra to high mileage. "Do not accelerate fast, avoid applying brakes!" This I have learnt by my own methods and am not copy pasting from anywhere else.

Why this mantra? Because the amount of fuel your engine burns is first and foremost decided by how open your throttle is. The secret of getting good mileage is to open the least amount of throttle for maximum amount of time. However whenever you want to accelerate, you open throttle more than what is required for the engine to run at that rpm. And this is an obvious requirement of acceleration so if you keep doing this, you will burn more fuel than what was required. Same thing for braking then, if you keep braking frequently then you will have to accelerate more and that will burn more fuel.

See it like this, you are in traffic and suddenly brake to 5kmph and then accelerate to 20kmph only to brake again to 5 kmph. This will burn more fuel than if you had kept the bike at 10kmph and not accelerated/braked at all. You will get BEST POSSIBLE mileage if every drop of fuel burnt is used to MAINTAIN your speed, not INCREASE your speed. And that's that!

As far as changing gears is concerned, the best shift point for all gears in Dazzler is between 3000-4000rpms depending on load. When I am riding alone, on level roads with light to moderate traffic, I shift at 3200rpms, with pillion at 3500rpms. With pillion on uphill climb, shift at 4000rpm or above. And smoothly accelerating after shifting, no hard acceleration after shifting at these rpms. If you want to accelerate hard then you will have to increase the rpms of your shift points.

And here is the deal now, I am running Joel's big bore setup in my bike and I get a consistent mileage of 48kmpl with max of 50kmpl (twice) and low of 38kmpl (consistent spirited riding with gear changes at 5000rpm and frequent braking and acceleration) but I have also got 45kmpl when keeping the bike at 6000rpm/80kmph consistently, with least possible throttle input, when touring on the highway. So I am speaking from experience.

Hope this helps.

Want to add a point regarding touring-

Many of you would already be knowing that around 53kmph in 5th gear, you'll find increased vibration from the engine. It is sort of a vibration that makes you feel like you have to shift the gear up to the next one (which you can't btw.. only 5 gears) to make the ride smoother.

When you expect to ride inside city and if you are conscious about fuel efficiency, shifting at 3.5k to 3.8k is your best bet. In this case you dont have to worry about the vibrations as most of the time you will be doing less than 50kmph.

If you're on a highway and expect to ride at 80 to 90 kmph, my suggestion would be to shift at these points:

1st gear to 2nd: 4k RPM
2 to 3: 6k RPM
3 to 4: 6k RPM
4 to 5: 6k RPM
in 5th: maintain > 5K RPM

You'll notice that you will be accelerating hard in lower gears, but reach 53 kmph before you're on 5th gear. As a result when you reach 5th gear you will be at around 5.5k RPM with quite a lot of road speed and NO vibes at all.

This is a personal observation, and is no trick of any sort; just natural mechanism of the gearing system and drive. My highway mileage is just above 58 kmpl (idle RPM at 1400RPM). And I'm mentioning this method here because I really loved the way the bike starts cruising in the 5th gear, with NO signs of engine stress/vibes and minimal noise, when you use taller gear shifts. Very useful while touring.

Also, a note to self: Buy a chain degreaser and lubricant (TVS?/Yamalube?) and check ride/mileage improvement.

Took my Dazzy to a Long Spin Yesterday. 495Kms trip in One Day

Full Tanked my Bike. Suffered from Heat. Suffered from Heavy Rains.. When I say HEAVY its Heavy with winds. Brushed off Floods. Conquered 5kms Rough Roads. Average speed of 80kph with group. Conquered Hills and Slopes

No Hiccups, No MisGears, Loves High RPMs,(I so love its engine, its like a bird whistling). No Electrical issues, Tire is grippy enough for a city ride. It can shoot QUICK from 0-80kph easily. Dazzy reached home with 3more Bars left of Fuel, .

I am so amazed that I have a Gem with me. Dazzler, InVicta and MegaPRo users, Be Proud!
