Re: Hero Honda Karizma ZMR

Need feedback on the Vadool Swift engine oil - did anyone used it, is it SS or mineral?? and also feedback on Bosch Spark plugs?? let me know your feedback..

Re: Hero Honda Karizma ZMR

Replies in bold sir jee.

Vadool? What on earth is that?
If you're referring to Veedol Swift, it has been reported to be an awesome oil. [MENTION=28527]sibun[/MENTION] da, is it semi synth?

Re: Hero Honda Karizma ZMR

You meant Amogh lol

I am using shell AX7 oil, will visit soon to SVC if i hear "that" noise again.

Re: Hero Honda Karizma ZMR

Knocking sound in zma and zmr are very common once the engine is hot.. but if you get a solution, let us know

[MENTION=32908]AmoghDox[/MENTION] Awesome snaps, buddy!
Where were the above snaps taken? I can't imagine snow-capped mountains on the way to Mumbai!

Btw, even I'm getting a metallic rattle if I rev the engine suddenly to 4-5k RPM. It resonates only at a specific rev band, and not below or above it.
This is different from Amogh's problem since this rattling is not noticeable while riding.
The mechanic who changed my headlight said it's coming from inside the silencer pipe, and the unit is faulty with some loose internal components. Since it's a sealed unit he advised me to get it replaced under warranty, instead of attempting any repair.
His point seemed legit to me, and I'll probably take the bike to the SVC to see what the Hero "authorized service engineers" have to say about it!

Re: Hero Honda Karizma ZMR

When your bike is cooling after a ride a mild tik-tik noise comes from the exhaust . This is the catalytic converter metal cooling and contracting . It is normal - no need for any worry . Tappet noise is continuous and sounds like a sewing-machine and occurs only when the engine is quite hot .

Re: Hero Honda Karizma ZMR

Hahaha true! it was not taken from my cam, I took some of the pics from my cellphone, that above pic sent by my friend he must've edited/ did unnecessary PP to that pic
will call you today see you soon.

Thanks, bike was in motion and even while downshifting/up-shifting it was noticeable noise (tappet) hence i was bit concerned.

Re: Hero Honda Karizma ZMR

@sounakray, you cannon't separately adjust the high beam and low beam. Both the beams would move if you try to adjust the beam adjustment screw. What I have observed is Karizma has better high beam than ZMR. The ZMR has vague dispersion on high beam and is compounded by using 55/60w bulb. The 55/60w Extreme Vision and Nightbraker bulbs are made for use in cars where the spread is made keeping in view to be in sync with other headlight. The placement of filaments is slightly different for 55/60w bulbs than 35/35w bulbs. So, the reflectors of both ZMA and ZMR are made keeping in view the 35/35w bulbs.

Using a 55/60w bulb in ZMR results in poor high beam dispersion, and it looks like a low beam mostly. The low beam and high beam are spread very closely. Where as IN ZMA, this problem is less (its still there). The high beam in my ZMA points much much better than ZMR. This is what I have observed.

@Divya Sharan, Veedol Super Swift is a semi-synthetic oil, equivalent to AX7 in Shell. This is a very very good oil, as good as AX7.

@AmoghDox, the ticking noise from the engine could be loose tappets (more valve clearance). Adjust the tappets, 0.1 mm for both exhaust and intake valve. The tappet noise is more pronounced if you use a w30 oil and will be muted slightly with a w40 oil, and will be muted significantly if you use w50 grade oil.

Re: Hero Honda Karizma ZMR

Thanks [MENTION=11210]ravi@17bhp[/MENTION] bro for categorically confirming what was till now my logical guess. Having different filament positions is what I meant when I said the bulb might have a different geometry.
Also, we shouldn't forget the fact that the X-treme Vision is an H4 bulb, while the stock one is an HS1 (specially meant for bikes), and like you mentioned, there might be minor difference in filament geometry (or it's allowance margin) between the two standards.


And BTW, I surely didn't expect that the high and low beams would be separately adjustable in a single-bulb dual-filament lamp, set in a rigid reflector unit I was just hoping that if I raise the light throw a bit higher using the beam level adjusting screw, then may be the difference between the high and low beams (I.e. the distance between the patch of road illuminated by each) would be more pronounced. This is because the light beams and the road will converge at a larger distance, thereby magnifying the gap between the illuminated patches.
Although it's a sound logic in theory, I'll have to actually try it out to see how it practically works out. :P

Thanks once again Ravi for such a clear and detailed explanation!

Re: Hero Honda Karizma ZMR

not Honda alone.. its preset in R15 and RTR FI its even present on super cars like Mclaren F1
its like a test run for proper functionality of fuel pump.. just like how all the dashboard things and rpm meters test themselves

did not see your reply below ..

----consecutive posts auto-merged-----

The tik tik sound occurs when your bike is turned off right??

if so, there is no need to worry about it.. it only means that your spark plug is working awesome and even after turning off it tends to spark for a while..

Re: Hero Honda Karizma ZMR

[MENTION=11210]ravi@17bhp[/MENTION];1028938 thanks for the clearing my doubts, I didn't notice the tappet noise since yesterday till today morning whenever I rode, ticking noise was audible very clearely day before yesterday when i was returning from Mumbai, I will take my motorcycle to SVC for the tappet settings which you've explained.

Re: Hero Honda Karizma ZMR

Let me know when you plan to go, n we can go together. I also need to do something about that silencer noise I'm facing...

Re: Hero Honda Karizma ZMR

Hi Raja, I was talking about the ticking noise which was audible when motorcycle was in motion.

----consecutive posts auto-merged-----

Sure thing mate, we will plan this weekend, you might want to show the clutch settings of your ZMR too

Re: Hero Honda Karizma ZMR

The tik tik sound you're referring to isn't from the spark plug, its the catalytic converter contracting back into shape. The sound comes from the exhaust.

Re: Hero Honda Karizma ZMR

The tap tap sound from exhaust is normal. Divya Sharan explained above why it is.

The sewing machine type noise from the head of the engine is because of loose tappets. Faulty cam chain tensioner also causes similar sound but its very different (a little plasticky noise). Make sure the cam tensioner is not faulty.
