i think its 7 am i right. some talking about 4 and 5 thats why i am asking

Stock one is 4 Amp battery.

It is different from previous cbzees and now its MF too...

Leave it for now, main thing is where did ur fuel disappeared,i doubt someone has stolen it 4 sure.

I'll try tightening them up next time they get loose. Thanks

I don't see any fuel stains around. Don't know if there is a fuel theft

but there has been an increase in it in my nearby area

Yes mate its 4Ah, i guess u didnt check its vroucher in showroom . IMO u will have to open that cage to check its Ampere ratings

All HH bike except ZMA-R and ZMR came with 4Ah MF Battery,New ZMA-R and ZMR comes with 6Ah MF battery.

But the Yamaha R15 V2 with dual horns have a 3.5amp MF battery only.
BTW, if we need to upgrade battery to Amaron 5Ah or 9Ah MF battery, could the alternator match its current rating?

Exactly but may be they have a powerfull dynamo to compensate with that and to assure it remains charge forever .

Alternator will charge it(with less current IMO),but wont overcharge for sure .

Mileage = Leaner or Richer carb

Greetings. I want to know about the carb tuning, how do i tune to get more mileage, is it towards the leaner or richer side. Or is it anywhere between the starting point of become too rich and starting point of become too lean?

Don't tell me not to play with the carb tuning, 'cause it's too late

Regards.

Lemme just try some formula...

I'm not an expert in science, but recollecting past memories i think Power [Watt] = Volt x Ampere I
or W = V x I
Our bike is 12 Volt DC and its alternator as per manual is 140watts
Hence
I = 140/12 = 11.67Ah.
Hence Alternator produces 11.67Ah of current.
Is this correct??

Yes thats correct but thats ai'nt 11.67 Ah, thats 11.67 A. Ah is used to denote the CAPACITY of a battery.
12V 4Ah : this battery can give :
4A for 1 Hr
3A for 1.3 Hrs
2 A for 2 Hrs
1A for 4 Hrs

Alternator is capable of producing that much of current (MAXIIMUM POSSIBLE). it doesnt always give 11 Amps. Depend on load and voltage of battery it changes. Current from alternator is divided into 2 parts IMO. 1 for battery charging, another for Headlights.

Yes absolutely correct...but it is at a specified RPM and more...at idling,and low RPM the alternator may not be able to produce the rated current.

Depends for wat purpose u r tuning to:
1) For better Mileage : Tune it Leaner (not too much otherwise it will affect engine )
2) For Better Power: Tune it richer ( Not too much as it would again affect ur engine)
3)Optimum Performance: tune it to the mid point (as close as u can get)

Don't tell me not to play with the carb tuning, 'cause it's too late

I hope u r getting lesser mileage than expected,tune i to Leaner (slightly)

. 1 CLOCKWISE turn of the Fuel Screw (I hope u know where to find it

) will be enough.

Regards

True...many of Karizma owners have switched from 7 AH(old) and 6 AH(new) batteries to 9 AH Batteries without any issue till date.Stock Karizma alternator rating is 188 Watts = 15+ amps ...and this current value is at 3,000 RPM or more.

Problem unsolved

@ PSR Sir : my stalling problem still unsolved

. at IDLE , RPM needle keeps moving between 0.8K to 1.5 K and finally engine stalls. I was running lean from past few weeks, can that be a problem ?? may be my sparkplug needs to be cleaned

Thank you for correcting me.

so it means no need to worry in changing to dual horns and when upgrading battery na?
