Re: Hero Honda Karizma ZMR

The 2003 ZMA had aggressive Ignition map in that it had more ignition advance and hence was slightly quicker...but the FE was low, and so the Ignition was re-mapped by Honda from 2005 models.

This engine is STILL produced by Honda and used in CRF 230 ,which is the most preferred beginners dirt bike....
Powroll BBR makes Big Bore Kit to take it up to 247cc...

Did you know that in ZMR the Fuel Pump sits outside the Petrol Tank , very near the Left side shield ?

Re: Hero Honda Karizma ZMR


Yup.. I know the 2003 ZMA's were slightly quicker than the later ones.. i had it during school time.. my dad got it for my bro and i used to ride it after he completed college.. so from 2005 to 2009, i used it when I joined college.. and before that I used to ride it once in a week to school.. The ride too was not as smooth as the later ZMAs..



Thats my Bro with the ZMA.. My Dad sold it off without letting me or my bro know else we would have stopped him..

And yes sir.. I know that the Fuel Pump is located beneath the Fuel tank on the left side.. i am always with the mechanics when they service the bike as they did a crappy work once.. and I had to pay for it in terms of waste of time..

They somehow managed to break the fuel inlet noze (plastic part) which lets the fuel into the Fuel Pump and they used M Seal to fix it and never informed me.. One fine day whenever i turned the ignition on.. fuel smell was flowing and i didn't realize it was from my bike.. i left it and after a week the fuel drastically leaked and it started falling on my legs..

so when my friend Manoj and split open the fairing and tank, we noticed that it was fixed using M Seal.. I have the pic of that part at my house somewhere.. I will upload it when I find it..

we spent almost 2 hrs on the middle of the road split opening the front of my bike.. we had a work around the same way those SVC guys did and it took us almost 10 trial and error method on how that would be seated.. and finally got it fixed temporarily..

had to place order for that piece.. my friend Manoj has very good knowledge when it comes to all this.. and when we went to order for that part.. they tried to cheat us saying it comes as a complete set along with the FI unit.. it costs sowewhere around 5000/-

I had to give a complaint on the Hero website to get the work done properly and they finally got me that part alone for 460/-

so Of course I know the Fuel Pump is beneath the Fuel Tank in ZMR

I try to fix things myself when it comes to my bike.. if I can't do it.. i take it to the SVC..

Re: Hero Honda Karizma ZMR

But sir, compared to a p220 engine, zmr is less in pick up and top end both. Then where is that extra cc going? Is it not contributing in anything? There has to be some field in which zmr gains due to that extra cc rite?

Re: Hero Honda Karizma ZMR

Where is the extra cc bro? Are you talking about 3 cc here?
Well, less power lends one big advantage to Karizma - long term reliability.
The engine doesn't rev up to insane levels, peak power/torque is in the mid range (as per today's standards). This leads to lesser wear and greater life.

Re: Hero Honda Karizma ZMR

Correct me if I am wrong.. I don't think cc has anything to do with power and torque here.. or does it?? as its just the size of the block.. right?? or do I have a wrong understanding..

ZMR fishtail issue

My ZMR is doing fishtail even at the speed of 20 kmph. Last Dec I met with an accident when the bike fell at 60kmph while taking a turn. There were scratches but no serious defect. I don't trust the service center as they are good for nothing.

Now I am scared to take turn even at 20s. Kindly help.
The rear wheel is too thin for my like, I am willing to change the tires to Pirelli sports demon to avoid this, will it help?

Thanks,
Shrey

Re: Hero Honda Karizma ZMR

You have had a Great Looking Bike...the 2003 ZMA looks really beautiful...sad you no longer have it...

The Karizma has a near flat torque curve..ie., there is power on demand in almost through the RPM,and gears,which is what the engine is designed for..remember it is designed to be a dirt bike where low end power is essential in steep grades...and to further augment it the CRF 230 has 13/50 sprocket scheme....The Compression ratio is a relaxed 9:1...the CRF also comes with 26mm carburetor and produce 18+ HP...In India where Fuel Efficiency is more important, the ZMA had been tuned to maximize FE .....
The CRF 250 R/L/M/X all are 4 valves per cylinder LC with 10:1 or higher compression ratio...Wish HH had got that series of bikes here
If you rule out the speedo error, then the ZMA and P220 will be almost same in top end + or _ 5 to 8 Kmph....

Re: Hero Honda Karizma ZMR

I regret for what my dad had done in my absence... I asked him to sell of my P180 after we shifted to Delhi and bring the Karizma here.. but he sold both the bikes.. and yes sir.. you are right.. she was a beauty.. only 2 of these colours throughout Chennai.. and one of it was mine..

Few more pics of my beauty sorry for adding pics of a ZMA here guys..



made a lot of changes in just 2 days.. removed the full fairing of the Suzuki GSX and fitted the original back.. and then after few months.. replaced the headlight assembly as it had faded out...



The original front fender had broken.. so we thought to get a custom made and then get it painted and we never had time..

Re: Hero Honda Karizma ZMR

Same top end. ??
Look you are comparing two totally different machines......one is the fastest indian and other the best tourer.......p220 can never touch karizma in touring comfort.....nor can a karizma touch p220 when its top speed and 110+ cruising.....pulsar definitely is faster than a zma....

Re: Hero Honda Karizma ZMR

You just quoted what PSR sir concluded, pls read the variables above it too. (The CRF 250 R/L/M/X all are 4 valves per cylinder LC with 10:1 or higher compression ratio...Wish HH had got that series of bikes here)

Re: Hero Honda Karizma ZMR

Boss.. you didn't read it properly.. PSR sir has clearly mentioned.. almost same top end + or - 5 to 8 kmph.. and its a proven fact that the P220's have the maximum Speedo error.. when the speedo shows 142 kmph.. they are actually doing 132 kmph.. and ZMR has negligible speedo error and again it has been proven... besides.. 4kmph is not much of a big difference.. P220 has got the grunts and punches.. no where has PSR sir mentioned same top end..

Re: Hero Honda Karizma ZMR

One thing everyone has cleared it to you. Second important fact: majority guys here have attained 127-130kmph. So according to a pulsar Speedo, add approx 7kmph(error MAY increase with speed), it would be roughly 134-137kmph. And p220 guys may have crossed the 140 mark on their Speedo? So 3-5kmph difference is absolutely nothing unless you are racing on a track which the zmr is not meant for. However only one fact I agree is that we cannot compare the two bikes as they are of a different breed. I just pitched in the topic as I was curious as to why a 223cc beast churns out only 17bhp. The answers which I got were more than sufficient and made me even more proud to own such a quality machine

Re: Hero Honda Karizma ZMR

Guys, i so often read about these top end & bhp/touque comparisons between bikes.. & i keep wondering with one question "why this kolavari di on all all these & only these things !!"

The first thing to wonder is, irrespective of what the top end speed of any x, y,z bike is, how many of us really ride at the top end ?? & how many times we really go to that level !! once in 10000 kms ?? the why keep talking about top end ?? Infact what is your average daily speed inside the city ?? a mere 60-70 kmph ???

Second, is a bike all about the cubic capacity, power & torque ?? If i have experienced it correctly from all those bikes i have ridden over years, I am sure a good bike along with a good riding experience is judged on a hell lot more factors; the overall weight of the bike, the weight distribution across the entire length, power to weight ratio, feedback from the tyres, feedback by the chachis, vibrations, a truly assured braking system, overall dynamics (i know how better i feel after i removed those extra wide mirrors from my ZMR ! ), sitting posture & you own weight transfer frequency... As far as i have experienced the avg speed at which you actually ride your bike depends so much on all these factors irrespective of the power n torque ! I so much believe that the attainment of speed is actually more about the word "confidence n control over your bike" , may be power-torque coming only second ! After all most part of our lives we actually ride inside the city, don't we ??

As harsh as it may sound, the truth is all these P220 or ZMR(s) are average bikes made for typical indian conditions n customers.. I cant say my ZMR is the greatest ever bike just bcoz i own one.. The truth is almost all of us own it coz we could afford that only... LOL.. The truth is neither a P220 is complete nor a ZMR is.. each one of these bikes give something & take away something else.. While you may zoom past other bikes with a P220 in the busy city roads, you would feel much better on the highway with a ZMR over a long journey... Then why waste time comparing or keep praising the one we own or keep showing the other bikes down !!

Last but not the least, the power & torque generation is just not about a cylinder & a piston.. may be we are forgetting technology here (compare a 600 cc Honda hornet producing 101 ps compared to a 650 cc Ninza producing a mere 71 ps) !! May be we are forgetting power distribution here !! & may be we are also forgetting efficient & sustained use of distributed power by the components too !!

Re: Hero Honda Karizma ZMR

Thats the thing I wanted to say....they are both different bikes and we do not need to compare them anyday........p220 has 21bhps of raw power....but its not as comfortable as a 17 bhps zmr...its all about weight distribution,gearing ratios,power delivery and sitting posture......

Re: Hero Honda Karizma ZMR

Everyone here agrees that p220 is different from zmr amd we just eanted u to know that psr sir never mentioned anything about dame top end. If u rrad him post again..

Well.. what i wanted to know was why zmr is under powered when they could have given it a few more horses just like how p220 dtsfi was upgrades to p220 dtsi.. and thats the explanation he was giving me..

You might not have understood it as u might not have gone thru the previous posts by me and few others.. no way will i compare my machine with a p220 as i know what my machine is capable of doing..
