Re: Hero Honda Karizma ZMR


The service mechanic opened up the fuel pump and drained out all the petrol which was inside.

There are three hubs.
One comes from the battery, which is the source.

The second connection is from the fuel tank. As you can see a tube is attached with a tool similar to a clamp/plier. That was to stop petrol from flowing out.

The third hub is for the injector.

Anyway, the pump seems to be fine. Now I suspect the fuel filter and the injectors. The problem still persists.
Bike lags as though its out of petrol somewhere between 3.5k-4.5k range.

I've been using system g for a while, so the injectors should be clean.
Have no idea what the problem is..

Re: Hero Honda Karizma ZMR

Leave the bike on main stand for at least 30 min. 1 hour preferred. Best time - morning.
Keep the screw on top, don't turn it in. The reading should be between min and max markers.

1500 kms is the max stock Hero oil can help.

I'll share my routine with all. Some maybe myths but they work for me.

1. Morning starts - 90 sec idling at least. (to office)
2. No revving above 4.5k or below 3k for the first 4-5 kms daily.
3. Absolutely no lugging EVER!
4. Idling for 30 seconds after every long city commute (>15 kms or 40 mins) before turning off the ignition.
5. Evening starts (ideally a gap of 8+ hours) - 45-60 sec idling. (from office)
6. Chain lubed always with grease.
7. Chain cleaning every alternate lube session.
8. Chain lube every 500 km.
9. Full sprockets dismantle + clean + lube every 3k kms.
10. Redline for a few sec once in a while every month.
11. Always fill in 1100 ml oil (1 L works too).
12. Air filter replacement at 9-10k kms. (no compromise)
13. Spark plug replacement every 12-14k kms. (no compromise)
14. Replace O rings every alternate oil change.

Removed my snorkel again to enjoy the roar. Will be put back in a few days. No harm to engine!

Re: Hero Honda Karizma ZMR


Bro also check the battery terminals and connections once for loose contact.

I remember meeting a ZMR owner at SVC who had same issue and the problem was with loose battery connections.

Just sharing my view Hope it helps.

Re: Hero Honda Karizma ZMR

Get injectors and fuel filter checked. My case was worse than yours. Not just lag, the engine would shut itself down specially while changing gears. I still don't know whar the problem was. But after getting the pump, filter and injector cleaned and fitted back, the problem has vanished and its almost a year and a half since its vanished.
Also add the ignition coil to your checklist. Very important. Get it checked.

Re: Hero Honda Karizma ZMR

Thanks all for the response. I was hearing mixed opinions about dipping the stick full or not. Now cleared.

Re: Hero Honda Karizma ZMR

1. Ha ha ha. Good catch! I meant not to lug.

2. Yes, inspired by them only. Many say its not needed for NA motors, but I feel it this way:
You go to the gym.
You warm up. - That's me idling at cold starts.
You exercise.
Finally you warm down/strech before going back, else you have body ache. - That's me idling in the evening.

3. Case all the way! Had it open for sometime, but put it back.

Re: Hero Honda Karizma ZMR

hey guys.... There is one issue these days on my bike coming up.. i thought before sharing with the service center I will give a try here as I think you guys will be more helpful..

many times when I run the bike the engine seems to gasp for the pull and feel that u giving the throttle but engine not responding like missing .. but when I go above 70 the engine tends to be ok..... also the pull is non linear . My bike runs on fully synthetic Motul engine oil with Knn Filter..... after running for some time it seems to get better......

I read somewhere that there might be some impurity in fuel tank. is that the issue???


and yes I do idle bike for 2 min before the ride every time.

Cheers!!!

Re: Hero Honda Karizma ZMR

(Assuming air filter, spark plugs and tire pressure are normal)

Maybe clutch plates too. How many kms covered?
What RPM does your bike show at 64 kmph, 72 kmph and 88 kmph respectively?

Get the accelerator cables/throttle body cleaned as well.

Re: Hero Honda Karizma ZMR


I will check the rpms and let u know..... kms- 35K....

Re: Hero Honda Karizma ZMR

FYI, ideally these should be the figures.

In 5th gear:
64 kmph - 4000 RPM
72 kmph - 4500 RPM
88 kmph - 5500 RPM

Re: Hero Honda Karizma ZMR

Where is the K&N installed ? Throttle body or inside the air filter box (under seat).
How often do you clean and re-oil K&N ?
If you are getting K&N cleaned from workshops, I doubt if they use K&N OIL to recharge the filter.

Re: Hero Honda Karizma ZMR

Thanks abhi, now my faith has been restored I thought there was no solution to this 😕

Re: Hero Honda Karizma ZMR

Its installed inside air filter box.
I clean it around 8K kms but do keep a chk on it.. I clean it myself I have my Knn Kit of cleaning it ..

Cheers
