I was very unlucky this time in Junk yard .
Couldn't find the RR Unit nor the P220's headlamp kit. I thought of putting P220's Ellipsoidal for High Beam but in vain.

Can u take a picture of your RR Unit and send me so that I can atleast guess its size. Hunting in Junk yard is pain. I guy showed me a RR Unit telling its of Minidor but it looked like a HUGE Transformer (also there were no wires for it, all the wires were cut to its neck). It was bigger than 2.5aH battery.

Try ur luck someother time

APE RR is small enough to accomodate with a bike. This is it.



And this is also a single phase from Bajaj GC1000, slight mods required



Minidoor RR is slightly bigger and costly too, but its not that as big as a batt, go for APE its very compact. This is Minidoor RR



From these pic only, I got the logic that it should work with our setup.

Thanks for that info

Then get ready for the treasure hunt ya

So, finally anyone got the right RR unit to extra charge the battery yet?

I really doubt that I was communicating with my regional lang after reading this

Dude, pls read the last post before this page, will give u a snap update of ur question.

I could not understand your first line.

I have already found those attached pictures of RR units, but, do they really help the charging? How was the result, after installing the same into Unicorn? Did anyone try it already?



UPDATE FROM MY SIDE:

Dude, no intention of hurting u anyway, just took it in a casual way forget it. I thought the entire post was self explanatory, my fault.

Yes, those RR's will boost the charging rate to use an HID or a higher watt bulb with an avg batt. The bottle neck in the stock setup is the RR which gives nearly 3.5A to the batt(enough for a 35W halo, not at all sufficient for the mod. U can go for any of these RRs to boost the charging rate as the coil will be atleast 60W, so it can drive a min of 5A out of it.

The circuit u've posted for Apache, nothing to do with a Uni so I dont think its useful. Correct me if am wrong. And whats the role of KB100 RR? Its suppose to feed a mean 2.5AH batt, so its obvious that it wont feed a 9AH. I didnt understand ur reading from the KB RR 3.4V. It must be, 3.4A I hope. Any way it has to give a voltage range of 13-14V, else it wont charge batt. Assume that its charging @ 3.4A, still its almost equal to stock RR, so there wont be any improvement.

For boosting mods, u need to check the amps out from the RR, its a thumprule in this.

I hope I've cleared ur doubts along with ur hurt feelings if any.

Shree, u've something to say in this as both u owns Uni.

The KB100 o/p voltage is with load or w/o load? And, this RR unit is to be connected directly to the lighting coil after disconnecting the lighting coil from the original RR unit. And this KB100 RR unit will only give a measly 1-2A which is designed to charge the 2.5Ah battery. I would suggest a better RR unit. And please post a diagram of how you have done the connections. We can verify that.

hii bro.. i hve the similar problem of lighting now i want to change the stock bulb of my xtreme with 55w bulb im having these doubts plzz solve them for me..
- how to convert all electricals to DC ??
-for coil rewinding wch rectifier should i use ??

Upgrade to 55/60W, do the coil rewinding only, no need of convert it to DC unless u intend to use an HID or for a flicker free light in idle speed. I dont think the RR has to be changed, as the extra current from the new coils are not restricted for lighting, its restricted for batt charger to increase batt life. I own a P150, done coil rewinding 2 years back, no other changes other than thicker guage wires with a relay will improve the brightness + stock switch life

Converting it to DC means bypass the light coil to the batt by swapping of RR unit to a higher cap one and slight wiring mods too. Not a big thing if u know the wiring diagram and have some knowledge in electricals. But its better to do this with a reliable auto electrician not with a mech, else u can enjoy smoke from the harness. (harness cost is 1500 and above and hard to source)

Changing RR Unit is necessary in case of Honda and Hero Honda bikes bcz RR Unit plays role to provide power to Headlight as well.

Shreeni, all bikes magneto power is regulated thru RR only. The point is while regulating AC, its just shorting the coils to maintain the voltage around 12-13. Its not restricting the current while regulation, but when the DC conversion stage, the Diode plays the role in current restriction. The OEM RR will have a less amps diodes to make it in a healthy rate of charging. For further reference, you can see this



Or refer Abhi's custom RR diagram. Note that after regulator stage the rectification starts, there's your lifeline man. Here Uni's lighting is AC, lighting wire is tapped from here, so there is no restriction for the light supply, only the batt charging is restricted to get the max life out of it. So no worries I think, once u do it without swaping the RR will make it clear. Its almost same as the normal AC+DC bike.

The less amps diode is not for healthy charging. It is to save cost as well as provide adequate charging. If it would have been bigger, it would have been better!

While maintaining 12-13V, if the power source is bigger, more shorting would need to be done. This can heat up the RR unit and damage it. That is the only reason why RR unit may need to be changed. Other than that, it is fine for AC o/p

1 of my friend just changed the RR Unit on his UNICORN with stock coil and he can easily run 55/60w at its optimum brightness. How is this then?
