@Raj:
Rewinding cost depends on the person who is doing it, but 200gms of AWG copper wire generally costs upwards of 230 bucks in my city.
Piaggio Ape RR costs Rs.1100 only.
I used the stock AWG 21 gauge wire.........very thin and low resistance wire, nearly 175 feet of it to rewind all 12 poles.
I did the works on stock coil but kept a new one in handy if the mods did not take properly for precaution,I still have that for any future use of mine.
Yes, I had the pic of the 12 pole stator assay and it is there on the Ownership thread posted.
Photo posted on the ownership thread had both versions of GS stator assay,
The ones posted by Vishnukmd was of the 2009 batch.
The one posted by me is of the 2010 batch.

You may have other questions too.........please let me know.

Thank you for replying so quickly. I got the hang of the procedure i need to follow. Now its a matter of finding someone to rewind the coil. How much did you spend for the coil rewinding and rr unit? Did you use 18 or 19 gauge wire? And lastly did you buy (cost) a new coil or used the stock one? Do you happen to have a photo of the coil? I think the photo posted on the ownership thread is of the newer version of gs. Isn't it? Thanks once again. Raj

Now whats left is refining it.
So that u can use the bike as it was without DC ........every switch working with ease.

3.Former AC phase relay: The head light and pilot lamps assay used the AC phase connection from your stator assay, with the stock rectifier gone and change in connections the AC phase is now inactive,what you have to do is to reroute the erstwhile AC phase through your ignition key wire which will lead it to your battery.Otherwise your headset would drain battery and can be turned on even when your bike would be without ignition and key.......now that would be awkward aint it ???

So this are the basic things on what needs to be done........if you have any questions please clarify, then if you want to know more ask me.

2.RR-Regulator Rectifier: Piaggio Ape RR is the most sophisticated RR unit in the electronics market,if unavailable you can use the Bajaj GC1000 auto RR or the TVS King RR,if still not found ,use Pulsar220RR........but you know complications increase and quality decrease as you move down the alternatives of ApeRR.
Now,the two wires from ur stator assay would go and connect to two gray wires of the ApeRR unit.The other two wires of the RR unit, vis, yellow and black would move to the +ve and -ve terminals of the battery.

Now that completes your DCfying the bike.

@Raj: I had done the Full DC mod with the wet work being done by an experienced motor electrician in my neighborhood.The concept was mine and he just completed the job with sophistication.

Drvmtm is my close friend and I kept a tab on how he did things and got an insight at his house after a lunch on a certain day, so I adopted a similar approach with his suggestion and converted my bike to Full DC.

There are three things that makes up the basic of this:
1.Coil rewinding 2.Selecting the correct RR 3.relaying the former AC phase through ignition switch to the battery.

1.Coil rewinding: The stock stator assay provides one black wire out of the coil which goes to the stock rectifier.Leave alone the stator sensor which is an aluminium unit attached with the coil,it is not our concern.Now, you have to rewind that coil and have to give rise to two wires instead of one black wire.

Hi there, I am Raj. I have a gs since dec 10 and always been disappointed with the light. I see that you have changed your bike to dc with doc's help. So have you rewinded the coil? Whom did you approach for the job as it can be done only by a professional? What gauge wire did you use? Do you have a picture of the coil after you remove it from the bike? Also did you have to change the oil gasket after you remove the coil? My understanding is that the gasket will break while opening and it has to be changed. What about the wiring job? And lastly did you bolt the ape rr unit to the bike? I know there are too many questions. Please be kind enough to answer them. I have little idea about dc conversion but afraid to do so in case something goes wrong. Raj
