Re: Hero Honda Karizma ZMR

Ok, so you were referring to graphics card wala fan!
I wonder if it'd help much though! Would circulate more air compared to no fan/motherboard fan for sure. But, the overall practical usability has a big "?".

On second thoughts, actually cutting the fairing (making intelligently designed gaps/holes) and fitting the fan (with protection from monsoon) may help in B2B traffic and high speed highway runs.

Re: Hero Honda Karizma ZMR

I second what divyasharan said, the mod you are planning would have a big "?" associated with it.
Would you be able to switch on the fan every time you stop in traffic? Even if you do, the airflow provided by the fan would not even be equal to air that hits at 10kmph. Does the zmr need extra cooling? I have ridden it and never experienced any overheating issues myself.

Like divyasharan mentioned better would be to carefully and keeping the aesthetics in mind, cut the fairing so that extra air can be directed towards the engine.

Thank u Uncle ji..

Waise log sahi kehte hain... knowledge age ke saath hi aati hai.. :P

Re: Hero Honda Karizma ZMR

It gets real hot at times bro. Say I return to city from a >150 km one way trip. That means ~150 kms were done at good speeds and last few kms at snail's pace. At this time, you can literally feel the heat. Rest of the time, its fine.

Re: Hero Honda Karizma ZMR

That one is chota fan uncle.. see this one..


And why cant we use water coolers as in Cabinets or like liquid nitrogen(used in extreme cpu overclocking)

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

Uncle ji, today as I am free so was thinking of getting these fuses from an automobile shop.. but I am little confused as there are 4 sockets in which one is empty.. do you have any diagram or something which could help me to puse the right kind of fuse in the right socket

Re: Hero Honda Karizma ZMR

We can't use this fan at all because it can't make do without its heat sink. Radiators don't need that. Secondly, liquid Nitrogen who start going nanny in the radiator and would eventually crack it.

Regarding fuses, get at least 2 spares of each and keep them with you.

The arrangement is like this:

15 7.5
15 7.5 15 7.5

Re: Hero Honda Karizma ZMR

Well mine does have serious heating issues. Even upon changin of oil, I get a strong burning smell. Am not able to pin point the problem. No leaks nothing. Had checked thoroughly. When the engine is hot, I get that katkat sound from the engine and a loss in power to such an extent that at WOT, the bike jerks as if its running on low fuel. Happens only when engine is hot. Is it an indication of seizure? My guess is the radiator but am not sure.

Re: Hero Honda Karizma ZMR

Engine getting extra hot is a pointer to bad tuning(afr very lean) which again explains the burning smell and the loss of power as in, the bike feels as if running out of fuel.
The burning smell may be because of the seals and gaskets taking the toll or the oil burning if there is a leak(even a small leak which is not visible enough can result into this).
Regarding the khat-khat sound its an issue with cam chain tensioner or the cam chain itself or may be even the tappets are making that sound. An experienced mechanic can be able to solve the sound issue without much problem.
The only thing that I am not very sure about is why are you experiencing power loss only when the bike is hot, the bike is overheating itself is telling us that its running a lean mixture. A loss in power when the bike gets hot can also be bacause of worn clutch plates. The clutch starts feeling sticky and severe power loss accompanies. Anything of this sort?

This is not a seizure, don't worry. Also do check when you turn on your bike the next time if its giving out any white smoke by revving it to around 5k rpm.(While stationary and after the engine heats up for about a min or two)
How much has your zmr clocked? Report back after checking.

Re: Hero Honda Karizma ZMR

AFAIK, he has done 32k kms approx. Abhi, that Simota is making your bike run lean. I suspect an issue with the cam. Do check for whitish smoke. That will give a clearer picture. IIRC, you replaced clutch plates 10k kms back!

Re: Hero Honda Karizma ZMR

Like Divya Sharan said If you have Simota air filter , remove and go back to stock ...or face early problems with engine

Re: Hero Honda Karizma ZMR

Well, the zmr using an open loop fi system should be able to compensate for the increased air flow, right?
I suspect something to be wrong with the fuel pump or the injectors for the bike to run lean. Clogged injectors can be a reason.

Re: Hero Honda Karizma ZMR

ZMR is closed loop PGMFi....so lean running is possible only if the Injectors are getting clogged or the air filter is allowing air beyond the ECM's control parameters, or the fuel pump's pressure is low...

Dear All

I've been trying to make up my mind to buy a bigger bike (over the Unicorn). My requirement is for a fuel-injected bike that won't cough and sputter every time I start the bike after 6-8 hours.

I am nearing 40 and the R15 I rode for a month was in no way suitable to me. Too stiffly sprung, I had to lean forward and I really wanted to avoid riding it.
My Unicorn was a lot more preferable to it.

I then tried the CBR250 that belonged to an acquaintance. I was still not happy. It was not refined as the Unicorn. I also disliked the leaning position, if only slightly so.

I tried the Duke 200. Refined engine, I could sit upright, the pickup was good & contrary to what I had read, it was not stiffly sprung. It was the best of the lot.
I didn't miss the comfort of the Unicorn this time. I recently did the CHENNAI-BANGALORE trip on my Unicorn. 330 KMs in 6 hours. The bike at 146 KGs, was just about able to withstand heavy cross winds. I wonder how the KTM (at 124 KGs) would fare. Constantly controlling the chain slack is a big pain with the Duke.

To those of you who have ridden these other bikes I would like to elicit your responses here. Each of these bikes - R15, Duke and CBR250 are technically superior, newer in the market and are designed ground-up when compared to the Karizma ZMR. In what way does the Karizma hold any advantage over these bikes? Are there any good reasons to buy one? I rarely see new "hero" ZMR bikes which makes me wonder why these young men are buying 90s technology.

I have heard that though the ZMR is inexpensive compared to these, the maintenance costs are higher. Plus the spares are not easily available. Not liquid-cooled etc. Your takes please.
