Re: Hero Honda Karizma ZMR

Completes 40,000 KM of journey in my ZMR.....

Re: Hero Honda Karizma ZMR

Update on my bike's condition:

With @plasmabhai's help, my ODO moved from 56666 to 56752 now. The bike came to life in 1 crank and idled in a stable fashion.
Gear shifts were horribly hard (@ravi@17bhp's point well noted). We thought it must be the oil, but still Ravi anna had mentioned about it. Anyways, we playfully adjusted the clutch freeplay and voila! It's so much better now.

Also, there was some smell from the engine in the first 15 kms but there's none now. Will keep a watch. No leakages so far.

The bike goes for an oil change and sprocket cleaning this Saturday.
Still looking for a few replacements like - front right indicator housing, windscreen, exhaust shield.

Update - I should be fit to ride from the 2nd week of October or so.

Re: Hero Honda Karizma ZMR

There is one from Castrol as well, keep the drain periods around 1000 kms for optimum performance,

Re: Hero Honda Karizma ZMR

Overuse of anything is bad.
Shell AX5 is 10w30 as mentioned above. - http://www.snapdeal.com/product/shel...0w30/713377814

Re: Hero Honda Karizma ZMR

Once I used 8ml/5litres approx.. The bike became sluggish for a while.. Not unrefined like you mentioned..

Re: Hero Honda Karizma ZMR

friends my bike is now taking much time to start also sometimes it happens that it doesnt starts at all
i think its time to change my bike's battery
wanted suggestions for new battery which one should i buy exide or amco or amaron
and of what amperes the stock one or 9amp bcoz i am going to install a hid projector in coming days

Re: Hero Honda Karizma ZMR

Exide is a better buy. but if you install HID, increasing the batter power is not going to help. the battery should able to receive more power from alternator.

so rewinding would help, but not recommended.

Re: Hero Honda Karizma ZMR

Correct me if I'm wrong, but the alternator already produces a healthy 238 W power. If the OP opts for a 35W HID, then it's the same rating as a stock bulb. The only thing he should worry about is the high current flow when the HIDs are switched on for the first time daily. That alone consumes >2.5 A current. High grade wires and a strong 8AH/9AH battery are needed.

Re: Hero Honda Karizma ZMR

actually what i meant is the alternator will produce peak power @ around 5000rpm. but practically it is not possible for us to ride at higher rpm always. especially in city areas. so what we have to do is to make the alternator to produce more power at lower rpm itself.

if upgrading the battery alone to higher power solves the issue, then our bike stock battery will never drain out and always have more than 85% backup. but this is not the case. most of the time our battery will have less than 50% backup that too if we ride mostly in city.

so either we have to ride @ higher rpm or rewind the coil. this is applicable for stock bulb also.

Re: Hero Honda Karizma ZMR

Since I find this discussion interesting, I'll take it forward.
Even though the alternator produces peak power at 5k RPM, the battery still charges at 3k RPM. Just that the charging is not at its peak.
Also, the battery dies not 'only' because of low charge, but because it has achieved the pre defined number of charge/discharge cycles, low electrolyte levels, worn out electrodes etc.

That's what my understanding says.

Re: Hero Honda Karizma ZMR

This is not hunk/extreme which produces 140 watt @5000 rpm.

Here we are talking about ZMR which produces 238 watt @ 5000 rpm and that too the alternator is three phase unlike other bikes which has single phase.

In a ZMR 35W Hid is piece of cake and even another 35 watt Hid can be used as fog lamp with the stock 35 W hid bulb. Only upgrading the battery for initial start up is required. Zmr produces more than 165 watt above 3000 rpm.

Re: Hero Honda Karizma ZMR

for start-up , ballast will take care of high voltage AFAIK. if ZMR produces more power which is more than sufficient for stock battery, then all i can assume is that most of the generated power goes in vain (unless bike electrical runs 24hrs). in that case we can upgrade battery but what are we going to gain by installing upgraded one.?


in that case we can change to new one right.? is it necessary to go for higher capacity.?

ok. if i install higher capacity battery, whether the alternator/practical riding rpm is sufficient enough to keep the battery fully charged. if not then purpose of installing higher power battery is not met. i mean why we need to do electrical mods which is not 100% useful.

to conclude, installing higher power battery is really necessary for ZMR ....?

P.S: No offense guys for dumping with so many questions, iam not an expert that's why i needed more explanation to tease my brain .

Re: Hero Honda Karizma ZMR

None taken! I ran on my stock battery for 3 years and 45000 kms in the process. I used a 55w Osram for > 2 years. Then, I opted for the stock battery again. Completed 11+ k already. So, no need to upgrade at all.

Re: Hero Honda Karizma ZMR

Ok if you want to learn, then let me make you understand in layman english.

So here goes the explanation:-

Lets consider three entities. We will compare it with a dam. Lets consider the battery as Dam, the reservoir as charge holding capacity(AH), the gates as load, and the inflow into reservoir as Charging.

So lets begin the simulation.

Ok lets take a smaller dam or battery as our simulation goes. Ok it will serve the purpose as the water coming in will be released through sluice gates. So the river will be adding the reservoir and the load will be draining.

Now lets come into second scenario. The river is flooded then the reservoir will rise rapidly. We will drain that by opening more gates. Same thing in bikes. The battery after getting fully charged will reject the charging and will be dissipated by heat in the rectifier. Here is no problem in battery.

Now lets come to another scenario. Suppose there is a drought and for irrigation more water is required. But a smaller dam will have smaller reservoir as a result water cannot be supplied in sufficient quantity. Lets come to biker terminology, you have two horns( highway blasters), a HID, a auxilary lamp for night touring. Suppose you are running on highway and night, you give indicator, the light is glowing, the auxilary lamp is running, and you are braking and suddenly you see a dog in front of you and you press your highway blasters. If battery doesn't have sufficient reserve then neither you horn will blow, your hid will switch off as it will not run at low voltage and your bike will stall at worst case scenario.

So why did i compare the dam and battery here.

You see the flood analogy, here the ZMR alternator is like flood, will charge bigger battery with no sweat. But we have to store the flood water in big reservoir for draught season. Thats where the bigger battery comes, which will store more amount of charge. Draught condition is when a lot of load is there on the electricals for temporary period which the alternator cannot supply.

Now got the answer or do you want any more clearing of doubt. Come on ask me.

Re: Hero Honda Karizma ZMR

@sibun Divya Sharan

thanks guys....now clear. so far i thought ZMR alternator is similar to HUNK/XTREME..where it produces low power.

but now came to know that its much more powerful....!!!!

P.S: First time i was explained in a weird way but crystal clear...!!!
