Re: Hero Honda Karizma ZMR

I'll do that too. Thanks.

Re: Hero Honda Karizma ZMR

Sir, let us for a moment consider that its a ZMA we're talking about. So water in petrol should lead to jerky rides all the time right? Or will it be ok till some rev limit?
This logic because we're talking about carb'ed bikes. How (badly) would it affect FI is out of my little knowledge bank. Pls enlighten!

Re: Hero Honda Karizma ZMR

I think if water is there in the petrol then somewhere the bike would stop & wont start for an indefinite period. Not sure about the exact behavior in case of FI, but in carburetor bikes the bike would start slowing down the moment water comes in contact with the niddle (as it would be floating around). You would revv hard to survive but the issue would continue & bike would stop somewhere.. this has nothing to do with the revv range. The issue would keep resurfacing till the time that water droplet is there inside the carburetor.

Re: Hero Honda Karizma ZMR

Yes, that would be the last stage when petrol would no longer reach the combustion chamber. But till then the bike should stutter, right? Or will it behave according to engine revs?

Re: Hero Honda Karizma ZMR

I had just edited my post guessing this question.. I have personally experienced the water in petrol issue, but that was a carb-ed bike.. engine revvs wont matter.. it is a fuel supply issue & engine would react every moment the water present intervenes with the fuel supply.. I remember i had to open the carb at the middle of nowhere & had to clean it long back though..

Re: Hero Honda Karizma ZMR

We will Talk about ZMR /ZMA and Fuel Injection....Water in petrol behavior depends on the quantum of adulteration....water being heavy will settle at the bottom of float bowl, and for small acceleration the Idle jet which is higher in height will be sipping good Petrol,.....and if you try to accelerate ,thereby introducing petrol through main jet, the water will add to the idle jet feed and make the engine hesitate,and loose power.....In Fi the mix will come under pressure due to fuel pump and get injected as spray into the chamber....so at reduced level of water it will actually aid in combustion, but once larger quantity starts coming in, the calorific value goes down, and the Spark plug will get short to ground due to water wetness....Practically what I had seen is hesitation and jerk in carburetor, and lack of accelerater pedal response in Car Fi...and if the Pedal is pressed hard the engine will switch off....This had been my experience...I have no Fi TWO wheeler to give specific input.
Would like to hear and learn from other members.

For cleaning out carb float bowl, you can unscrew the bleed screw at bottom and bleed the Petrol in the float bowl.

Re: Hero Honda Karizma ZMR

wat would b the speed of bike at 2.2 to 2.5 in 5th gear?

My bike is still unregistered am driving around with a disabled speedometer

Re: Hero Honda Karizma ZMR

2.5 is 40 kmph. Avoid riding in that fashion. Upshift post 3.5k.

Re: Hero Honda Karizma ZMR

Calculation.. 16kmph every 1000 rpm in 5th gear..

Which means 16*2.2 = 35.2 or 16*2.5 =40

That will strain your bike engine.. shifting at 3000rpm + will do..

Re: Hero Honda Karizma ZMR PSD

Hi;I am proud owner of Karizma ZMR 11500 done almost 1 year. I want to change stock rear tyre with PSD 110/90 18, in bangalore tried almost all the places and could not get them. Even tried places referenced in the earlier post to hear that they are out of stock.Also I am thinking to change engine oil from stock to Shell Ax7 10w40.Any suggestions regarding tyre please

Re: Hero Honda Karizma ZMR

I upshift way past 4.2 or 4.5k rpm The problem is my downshifting .. I am not yet used to the engine sound of ZMR and having hard time figuring wether to downshift from 5 to 4 or not..

Re: Hero Honda Karizma ZMR

Its been 4 days that my bike is with the mech. That injector joint is no where available. They say it'll take 15 days to arrive on booking. Feeling damn depressed

Rreneav bro- is that part in stock near your place? And how many days may it take to arrive?

Re: Hero Honda Karizma ZMR PSD

We dont have much tire options for 18" alloy wheels.. psd is the best option.. else the stock.. other than this we dont have much tubeless options. I am currently running on michelin sira street on front and back.. front tires are pretty good.. but the rear tirea are slippery on wet conditions..

EDIT.. Forgot to mention.. they are not tubeless.. i am using them as tubeless
