Re: Karizma/Karizma R

Thanks a lot [MENTION=52772]AK3D[/MENTION] and [MENTION=11210]ravi@17bhp[/MENTION] ! Will replace the RR unit soon.
By the way, are there any cheaper alternatives for the Karizma RR unit ? Has anyone tried it and what about its reliability ?

Re: Karizma/Karizma R

The best you can get is from Karizma only.

Re: Karizma/Karizma R

From what I understand Ravi, the bike will run even without a battery. However best not to let the battery die out as the battery capacity then diminishes, leading to a lower lifespan.

Only buy the older RR unit for the Karizma, as mentioned in my earlier post. That is of a superior quality. [MENTION=32286]psr[/MENTION] - pre 2011, right?

Re: Karizma/Karizma R

If the RR unit fails, the AC current from alternator would reach the battery and the end electricals unregulated, which would destroy the battery and the bulbs. As Yashwanth mentioned above, the mechanic said to him that the bike starts only on battery power, which means he has disconnected the power from alternator. Its logical to do so in case of RR unit failure. Please correct me if am wrong.

Re: Karizma/Karizma R

From what I discussed with [MENTION=32286]psr[/MENTION] a while ago, it seemed that he ran the bike without a battery for a while, and it gave him no problems. His input would be better for us so we know what's going on .

Re: Karizma/Karizma R

Okay. It would just be a guess without accurate details. My guess was based on the info Yaswanth posted above. If the bike is started without battery, then alternator is not disconnected and power is being supplied, in which case we have to see what exactly the mechanic did to disconnect the RR unit. Or did he directed the alternator skipping the RR? Lets wait for PSR sir's view.

Or maybe the battery is fine, RR unit is fine, and may be there is some loose contact/short somewhere in the wiring.

Re: Karizma/Karizma R

The bike will run without the battery, "Only " if your RR unit and other electricals are running fine/ are in healthy state, otherwise not. If the RR unit fails(or wiring by passed) and the battery is disconnected, the bike wouldn't start as there wouldn't be any supply of power for igniting the spark plugs. In this case (RR unit failure/over heating), a properly charged battery in a healthy state would last for appx 350-400kms(upon constant riding). We had a similar situation, on one of my friends bike, where we bought a new charged battery in Perinthalmanna(KL) and rode back the bike to Bangalore.

P.S: The new battery is better to be used under emergeny/Stop gap solution, not as a permanent fix. Chanhing the RR unit( in case that's the fault, would be ideal ).

Re: Karizma/Karizma R

Let me share what I experimented and what results I got...
1. When my battery went Kaput, I did not replace it immediately since I wanted to experiment .I wanted to see if Karizma will run normally with flat battery..I kick started the bike and engine came to life and would ride normally....In the night also the bike ran well with headlight , horn and Turn light working properly. It then dawned on me that with battery not helping out the RR Unit must be under full load operation..So I touched the RR to feel the heat, and almost got burned....So the next DIY was to fit a Aluminum heat sink for this. After this I ran the bike like this for 3 months without any issues, and later installed an Amaron 9 AH battery..What I found was the RR unit heating was only marginally less WITH the battery, and so Shared the Heat sink DIY in the thread here.
I had never run the bike without battery for long, only for 3 days for short trips of 8~10 Kms in day time, when I found the bike to behave normally....I know of tourers who had failed battery and have returned home safely in ZMA.
If the RR unit OR the Stator Coils becomes defective, then ZMA is at the Mercy of the Charge in the Battery Only.
@yashwanthBK there are no alternatives for ZMA RR unit. Try to get the pre 2011 model RR like @ AK3D said, since they are more robust . Fix an Aluminum plate as heatsink under the RR unit ...DIY had been posted earlier in this thread.

Re: Karizma/Karizma R

I am guessing this is the DIY you are talking about. Can you please post a pic of the heat sink attached to the RR unit?? It would be of great help

Re: Karizma/Karizma R

Yes, I failed to consider that his RR would have been in working condition at the time

Thank you. Of course I didn't consider that his RR must've been fine then
The amount of information and learned people in this thread is very encouraging. Here's hoping it stays that way.

Thank you [MENTION=32286]psr[/MENTION] ji for the input.

Posted in my two links above. Check the positioning.

Re: Karizma/Karizma R

We 4 just did a 1200 kms trip from thrissur to velankanni and back on 2 bikes - Karizma zma & fazer...

the trip was just awesome especially the long rides in the deserted NH67 during the nights .. We maintained a steady pace of 70 kmph and even blipped to 90kmph at times..Got an awesome 43.7 kmpl for the karizma with a pillion on board and a hefty luggage of 9kgs..

reaching the destination i found noises coming from the panels (quite irritating too)





the same panel (comes with 3 screws) towards the battery compartment resulted in this wacky noise .. how much does this panel cost ?? is there a way to remodel the broken thing or something ??
also there is this squeaky sound from the rear suspension whenever i sit (i went on the trip straight after my 3rd service) ..i have set the rear suspension to setting 3 to get better handling .. Any idea on what suspension setting is the best for both terrains (cruise and city) ??

Thanks in advance

Araldite...

Re: Karizma/Karizma R

Actually the existing RR unit in my ZMA has been damaged, the mechanic said he could see smoke coming out of it. So he had simply disconnected the RR unit. Which means the battery wont get charged while running and the bike will run as long as the battery has power.

Luckily @SriramEfunds came to my rescue and had offered me to sell his RR unit for half the price, which he had bought earlier it seems. Thanks Sriram anna !
Went to the mechanic today, got the RR unit replaced, and now its working fine! (Except for the headlights, but i think its because the battery needs to get charged up a bit). Running without the extra Aluminium heatsink for now, planning to fit one before touring.

Also had a great time with you Sriram anna! Doing D.I.Y's, discussing bikes, etc. Your knowledge, especially on 2-strokes, simply astounds me!
Special thanks to @AK3D sir , Ravi anna , @psr sir , @phanikar sir for the immediate response and the information.

Re: Karizma/Karizma R

Hey guys please help me out... Should I fit the k&n filter in the air filter box or to carb directly.. If I fit the filter directly to the carb should I remove the air filter box completly.... And any other things that should kept on mind... Also my rear tyre is pissed of which brand of tyre should I opt for....
