Re: Hero Honda Karizma ZMR

Thanks!!! Close to 20 at what rpm??? You mean at redline?

Re: Hero Honda Karizma ZMR

NO, unfortunately not.. a bad comparison may make you appear better.. but it doesn't make you real good..

this march only one of my team members asked me, boss i sit for less hrs than the other guy & still deliver results.. so am i not worthy for an L1 appraisal ! I just said, my dear friend you still deliver in 9 hrs while he does it in 12.. lets talk next year when u bring it down to 5..

Re: Hero Honda Karizma ZMR

But now if a person is in a dilemma between p220 and a zmr then always what we say is that ours is a bit relaxed. Hence more suitable for touring in the mid-revs as you mentioned before. So when compared to a p220 we can claim that our stress is less rite. That's my question. But yes when looking at the figures we do get the notion that our engines are stressed than ideal conditions. My point was in keeping the pulsar in mind. Cause I have adviced the same to many buyers and I hope am not wrong!

Re: Hero Honda Karizma ZMR

big thanks to [MENTION=32286]psr[/MENTION] sir, my ride has indeed become vibes free after using rimula r4
and also i am thinking of replacing the right rvm since the allen screw had to be replaced and the svc stores person said that they do not stock the allen screw.
can any one tell me if it is available any where since the rvm is in good condition.

Re: Hero Honda Karizma ZMR

Good to see tech discussions in the right direction.....a longer stroke engine is slow to rev and because of the peak piston velocity limits ,has red line ,and limiter,at a comparatively Lower RPM...but the longer longer stroke helps in strong torque,and if Fueling and gear ratios are ,designed and selected properly ,will result in Flat Torque curve through out RPM.

Honestly the people to be thanked are engineers in Porche and international Bike riders, who had reported valve train problems ever since the ZDDP was reduced/removed from Gasoline engine oils...I had followed their threads and found that using an engine oil with ZDDP ,and without the friction modifiers is the way to go in our engines.....their posts led me to search for a Diesel engine oil which would be locally available for use, and found Shell to fit the requirement.... Internationally Many Kawaski and Suzuki riders are shifting to Diesel oils for this reason...a recent Paris Dakkar rally participant on a DR 650 had used the Shell diesel oils with good results.....
So these are the people who taught me, which I share here..

Re: Hero Honda Karizma ZMR

@ all above...
MPS values of prominent Indian bikes (Top bike is the most reliable one. Bottom one is the worst) Read at normal conditions


Bike MPS
Duke / 200NS 16.33 m/s
Pulsar 180 16.92 m/s
RTR 180 17.34 m/s
Ninja 250R 17.85 m/s
RE 350/500 18 m/s
CBR 150R 18.09 m/s
Karizma R/ZMR 18.76 m/s
CBR 250R 19.25 m/s
R15 / V2 19.57 m/s
Pulsar 220 20.8 m/s

Here, bang for the buck is always the Duke. But when it comes to touring, the best tourer is always the Ninja 250R, Followed by the RE and then our ZMR

(I never considered the CBR 150R as a tourer. Coz I feel cramped on it )

So compared with the prominent contenders like P220 and R15, ZMR is indeed a good package. Also, in the R15, one needs to redline it often at lower gears to maintain the torque curve. ZMR owners because of its linear mid torque range need not do that. That means, we seldom rev karizma engines compared with others and so more engine life.

Re: Hero Honda Karizma ZMR

What??? Which company are you a manager in? I'l stay away from it lol. (typical manager mentality! )

True about ZMA/R, but not exactly about R15 bro. V2 has peak torque low down at 5.5k RPM IIRC. It does make peak power at 8.5k, but delivers the moving force much below. You need not red line it often. That complaint became history when V1 was phased out.

Re: Hero Honda Karizma ZMR

Oops sorry bro. I meant about a R15V1. Coz I usually rides my friend's V1. Have never tried a V2. Maybe the torque curve is more linear on it. V1 was like a diesel car. Till the turbo charges in, it was like a passenger boat. Afterwards a speed boat Also, I think R15V2 and ZMR will be on par with reliabilities then. Coz R15 uses aluminum forged pistons and all. So as per my knowledge, if the piston design is made to a higher grade, the closer the manufacturer can make it near to the MPS redline value. Also, the CRF230engine is always known for its reliability. Have never ever heard what is a seizure for a karizma.. EVER. So....

Re: Hero Honda Karizma ZMR

I don't use the Allen Screw.. I am using the normal screw and it is much better than the allen screw.. by the way.. which ones are you talking about? the small ones that fix the RVM to the fairing or the Big one??

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

RE cannot be considered a Tourer IMO.. I mean.. i find it no where near comfortable with all that vibrations everywhere.. thats the main criteria to be a tourer if you ask me..

I understand the love for that machine by many people but that bike just doesn't attract me.. the bike doesn't run above 100kmph at long stretches.. and the amount of heat it produces makes it difficult to ride it during summer tours.. the Pro Biker Gloves tore off in less than 3 months for my friend and I am using mine for almost 2years now.. and there are only 2 tears on them.. middle finger and the ring finger.. that too because my friend used my gloves while riding his Classic 350...

Ninja 250/300 are acceptable.. these are monsters in sub 500cc machines..

Re: Hero Honda Karizma ZMR

i am not able to find it anywhere and i am talking about the big one that fits the mirror to the holder.
i guess allen screws are used so that parts are not robbed by any thief

Re: Hero Honda Karizma ZMR

Maybe.. but what makes you think the thief won't be carrying a allen key with them??

Re: Hero Honda Karizma ZMR

may be you are right.
they are carrying that too
have you replaced the big one with the normal screw, did you get it in the svc or any other hardware stores?

Re: Hero Honda Karizma ZMR

On layman's terms:

Going uphill (steep)–

A short-stroke engine needs a higher RPM on a lower gear, say 2nd gear.

A long-stroke engine doesn't need high RPM on the same gear compared to above.

[MENTION=32286]psr[/MENTION]. Please correct me if I am wrong.

However, when we talk of Bullet CI 350, the above doesn't hold too much ground (barring the fact that long-stroke engine last longer, and Bullet is proof personified). There are massive transmission losses in a Bullet due to an egoistic separate gear box, baba Adam's push-rods, sub-standard quarrelsome pinions, and of course the religious oil leaks from all places imaginable. The separate clutch is a boon though (only if you fill it with ATF).

Re: Hero Honda Karizma ZMR

Dream Machines stocks spares to the big screw.
Also, I need a ride on 28th as your pillion. I won't be taking my ride. Its not in the best of health.

Ha ha ha... Baba aadam k zamaane k push rods. Ha ha ha.

Re: Hero Honda Karizma ZMR

he he.. Oracle.. 12 summers already spent in my professional career.. btw, I know where you work I was offered to manage the team for the same account when I was with Infy.. world is very small u see !

quite right abt V2.. it shows it's true color once you cross 5K mark on RPM.. no need to redline.. i never had to..
