Hello, I am very impressed with your bike maintanance and caring, I have a 2004 model Cd cdawn marron color which is same in look with headlight, wiring, cables, tail light, but the back tyres are 2.75inch wide instead of 3.00 of yours, 2.75 is not so much gripy or comfortable, and also the meter console has no fuel gauge ,I have equiped the bike with side luggae vanity box so now the equation is more of a unstable side, So i will be changing almost new like back tyres(12,500 KMs total bike ran> this odo might be funny for so less riding) to 3.00 inch, and by the way how much do the handlebars vibrationreducing weight cost you , I will also try to put it, by the way which engine oil you use I use hero honda's.
I will post my bike's photo soon.
OK ,bye for now

Your's is perfect .
I seldom clean it since it's covered and my regular use of EP90 oil doesn't let it get very dirty . SAE90/EP90 gear oil used as chain lube is self-cleaning . It flings off the chain at speed and takes all the dirt with it too , try it . Dirt mainly accumulated whenever I have used grease or a heavier oil(140) . I think I have cleaned this chain-set just twice in 10k kms . That too with kerosene and toothbrush and rags right on the bike . But I do drip some oil on it every weekends or before long trips to my village . Never un-mounted the chain - just unscrew two #10 nuts and remove bottom cover only , brush on the oil with toothbursh(always kept ready inside the oil bottle),close it . Baas, 5 minutes job . You can call me lazy bummer or whatever - but I ain't spending any more effort on a 500 Rs part . I feel it is more important to lube it regularly(weekly) than to service it very good once and forever. I've seen the the bullet guys take out and clean their chains and lube it in molten grease/wax in pans .. .
Kerosene is freely and cheaply available in west-bengal either subsidised(from ration shops if you have card) or from open shops (non-subsidised and dyed blue in colour) . Same elsewhere in India too I think - mitti ka tel . Look around .

There is indeed a rubber cap on this vent hole . It has piece of shaped foam inside it and the rubber cap is held-on to the tube end with a wire-circlip grip (same as the fuel lines on tank and carb) . The free end is pinched into a duckbill shape. This hole is there to allow excess oil and splashed-in water etc to safely drain/drip out , and the cap allows that . But it prevents water ingress from outside - in a way it's a valve . I have dismantled and cleaned this tiny part recently . I could not help my admiration for the amount of thought that has gone into the design of every small parts on the Splendor like this air box . You'll notice that the airbox is also having an o-ring seal for the cover .

You can rejuvenate difficult to obtain ,old o-rings by first cleaning it with warm soap-water and then drying it and keeping it immersed in motor-oil (the one you call mobil) for a few days . Take out , wipe off and install .. it'll last a few years more if intact(not broken) . Usually I will also lightly grease even a new o-ring before installation , lasts longer .

hey hello,
I have also cd dawn old steel mudguard one, so want to bring brightness to the very low power headlight so what are the equipments reuired to get this type of lighting done and also store in Jamshedpur, As I also live here Jamshedpur Sonari. by the way which year bike you use

What if it is not in its place? any side effect?

I tried make it hot boiled in water hoping it may retain its shape but nothing happens.

U can get little brightness up by changing lights to led and removing the wire to the back light will increase your brightness. Also u can switch to philips premium H4 bulb has more brightness. You cant get higher brightness and no one can do this....there is no shop in jsr who can do this.
I've 2003 model.

Best would be if you can replace the entire headlight assembly with current CD-Dawn's MF Headlamp assembly including it's 35/35watts HS1 Halonix bulb . The current CD-Dawn's headlamp is quite good . Buy the OE set . Cost is reasonable . You'll get it at the HeroHonda authorised parts dealer for Bengal - Bansal Motors , Kolkata at Wellington Square near Jyoti Cinema hall .

I've created by my own before but dont know where it has fall down. the wire-circlip was broken due to junk...
Will make it again.

Btw , what's that trick ? I've no idea how to undo that chain lock correctly , may need that someday .

Can't describe it in words,I will post a picture which is self explanatory.

Replies in bold.
See the reply in bold just after photo of air screw o-ring.
Both the o-ring and the rubber cap and clamp, all are available. If you want i can courier it to you.
You can change the back tyre to 3.00-18 without any problem. But adding a side luggage carrier will never dis-balance the bike. Look for other things like improperly seated tyre, or chain adjuster not adjusted equal in both sides.
The handle bar weights are from pulsar.
Each weight cost Rs.70.
Two allen bolt each cost RS.10
Two square 10 no. bolt Rs.4 each.
Welding the bolt to handle weights cost Rs.20.
Also you have to make hole in the factory grips to fit the weights.
And regarding your running, my 4 months running is more than your total running.
And regarding the first model CD dawn, i know it very well because our tenant had it and i have ridden it a lot.
While it looks same as JOY it has some difference:-
1. Lighter in weight than joy
2. Front shock absorber is like splendor and longer than joy
3. The front mud guard is different
4. The quality is different as else how will you see the price difference of almost Rs.10,000. Joy materials were of higher quality and CD dawn was launched to eat into boxer market which it did successfully.Still CD dawn had greater quality than competition. As you know hero honda never compromises on quality but still joy is best quality from hero and this has been confirmed by my mechanic and showroom. But sadly it didn't find acceptance in market.
So naturally i find all other bikes to be a shade lower in material quality. Even my new extreme i feel is lower in quality than my joy.
5. Joy has multi focal headlight and back light while CD dawn has plain reflector.
6. Cd dawn has much better light output than JOY.
7. CDI is different and magnet is also different.
8. Cd dawn has side handle lock but joy has ignition handle lock.
9. The meter console is different
10. CD dawn feels free to REV than joy because of different CDI and lighter magnet.
11. The front tyre of CD dawn is 2.75-18 while joy has a factory fitted 2.50-18 and i have not changed the size.
12. CD acceleration is slightly higher than joy because of weight advantage and also change in CDI.
Post a photo of your CD dawn and i will guide you how to retain showroom finish.

No man i didn't wasted my time seeing fault in other things,
u guys told me before adjusting air filter & Carburettor should be cleaned, so I said it is cleaned 500 km back.
I was agreed to change it because it's very cheap. You guys told me to check your timing. I respect you so I was doing what you're saying.


Anyway, i feel sorry if i irritated you. that was my mistake i apologize

Yes man i want two float bowl o-ring (if its not Rs.800), two o-ring 27x2 (9130102800), carburettor host pipe clamp, and that rubber cap please

I didn't get irritated. It was because i was sure your o-ring was faulty but you didn't listen to me. Simply if you has opened the air screw you can easily know the fault.
See my post no. 1089.
Ok, today night i will see the part and let you know. I will also ask the float bowl o-ring and let you know.

How is my new Champion plug looking in 500 odd kms ?




Looks awful to me !




Me too running MRF Nylorib 2.5x18 at front on my Splendor+ , replaced tyre to downsize as soon as I bought the bike since I was comfy with the lighter handling of this size for a long time from my Yamaha RX to Crux . Hopefully this won't cause any long term problem with the front suspension etc of the Splendor .
New CD Dawn has really good and nippy acceleration and torque , better than my Splendor+ at the low end , haven't tested above 50kmph though . Better electrical and lighting too because coil redesign . I just rode my friends new one the other day . It's lighter and sprinty, handling and ride feel is different , didn't like turning/handling over the Splendor's .

@Pinaki Ji
The spark-plug looks to have nice light chocolate color.
Did you lubricate the threads with oil ?(First few threads have hard black carbon deposit)

Your spark plug is of correct color. However a little leaner will help in sharpening the throttle response and prevent carbon deposit on head. However it is best tuning if you are riding for long distance daily like me. Else if riding in city a slight leaner will help.
I was not talking about the new CD dawn. I was talking of the old CD dawn which had the same engine as ours.
The new model CD dawn shares the same engine as splendor pro, passion pro, CD deluxe(new model), splendor nxg. Those engines are different and their fueling and firing are also different.
The new series engine is more free and has more pick up because:-
1. The maximum torque is 8.04 NM @ 4500 rpm and 7.8 bhp @ 7500 rpm. The y2k engines in splendor/passion/ Cd dawn(old model) have 7.8 Nm @ 5000 rpm and 7.8 bhp @ 8000 rpm. Joy has 7.8 bhp @ 8000 rpm and 8 Nm @ 5000 rpm. So they making torque and power at lower rpm makes them have nifty acceleration.
2. They have thinner chains which decreases the mass of final drive and thus friction and thus feel free to REV.
3. They have DC CDI so their firing is uniform unlike our AC CDI.
4. Our rocker arms are of sliding types on camshaft but the new models have roller bearings on the rocker arm.
5. The carburettor and air filter are different so has better tuning and hence more better performance.
6. Now all have 44 rear teeth sprocket and the increased torque of 8.04 Nm increases their pulling power.

@sibun
if my engine is as same type as splendor/passion then why it doesnt go beyond 80 kmph :-( having 42 teeth sproket & 3.00-18 tyre. Never ever gone, previously even it was 80 kmph on 2.75-18. In fact now it sud go beyond 80 coz of more diameter of a new tyre.
