Thanks

That's the spirit! Just wait and watch.

The post is linked in his signature. I'll just quote from the guide he posted.

whats the cost of airfilter and sparkplug?

Airfilter costs around 120 and spark plug around 140 odd I think.

The Iridium Spark Plug costs 550.

how we can adjust the disk brakes?

By 'adjust', if you mean tighten or the like as it is in the case of drum brakes, not possible. But, you could change the disk pads to Non OE ones and get more bite.

Thread Approved and Merged

Disc brakes are self-adjusting . i.e it has a mechanism which keeps the gap between the disc and pads same as the pads wear down . However you can adjust the distance the brake lever travels to engage the brake (free-play) . Check the owner's manual for that .
I should again tell you that if oil gets on your brake pad (or brake shoe) once , it is impossible to clean it out , and the braking shall remain compromised (plus it may soon develop a squeaky brake noise) . It's not relevant whether your pads are 15 days or 15 years old in this case .The disc(steel) is however cleanable with some effort . Moreover brake pads(or shoes even) are too cheap parts to risk safety, and your braking may actually improve with after-market asbestos pads , than the OE non-asbestos ones .

thanks sibun for helping

Thanks sibun. is that instruction completed???

this is the sound from engine. I dont know you can hear it well. plzz try.
Is the sound from camshaft bearing.??

wats the use of iridium plug?

Self cleaning plug, better option would be the G Spark, its also self cleaning but only Rs.120~130/-

As i have told before do not fiddle with the new bike. New bike will vibrate. As the engine gets free and a thin layer of carbon gets deposited on head, your bike will be smooth.
My extreme was also vibrating a lot, but after 6k the bike has gone exceedingly smooth and still smoothening. Also use 10W 30 oil rather than other oil to help in engine settling.
Also as i have told else where hero honda engines take as long as 10k to be completely free. So do not fiddle with it now.

You cannot adjust disk brakes. As the pad will wear out, a slight increase in lever travel will be there.
Yes, my instruction is complete.
Yes, that sound is from camshaft. The bearing race is broken and presently the camshaft is running without balls. The small bearing has broken than lies opposite side of timing sprocket. Also the rocker arms are damaged by the broken camshaft. Do not ride in this condition as it is quite risky. Escalate the issue to hero honda and if possible upload the video by an e-mail to hero honda. First repair the camshaft and then think about mileage. Low mileage is also because of the camshaft as it is not properly opening the valves.
You have a 3 years or 40k warranty. Fight for it. Usually no use of wasting time with service center, just send a complaint to hero honda or regional office. If possible find regional office address and go and directly meet the engineer. Do not leave it and also do not ride it in this condition.

Hi Sibun!!
I tuned carb as per your guide

step1. Engine warm up
step2. air screw tightened (clockwise rotation)
step3. increased idle to 2000rpm by idle screw
step4. i rotated air screw (anticlock directio) until i get highest rpm ,my case it was around 3300rpm approx
step5. air screw rotated in clockwise to reduce the idle & it came to around 2700rpm
step6. now idle screw adjusted to 1000rpm
niddle is stable at 1000rpm , accelerator is fine

Is the method is fine or any mistake or other tips i can have from you ?

slight variation in the needle (1000 to 1200 rpm ,is it fine????

@Sibun,
Can you help me finding NGK G-Power plug for my ZMA in Bhubaneswar ??
