That is a real Eye sore with that alternator stick ing out were you can see it.

I have the Poorboy Alternator conversion, it is concealed under the left side cover, you dont know its there, unless you look into the shark vents yu may be albe to see it if you look close.

My 2 cents

I don't think I like the one in these pics above, just looks weird. I seen a bike with the poorboy kit, looks much better in my opinion. What does the poorboy kit cost and will it fit on a 1100 Interstate?

You Can buy the Poor Boykit from Don Piggot

His E-mail: [email protected]

I thinkthe kitwas $175.00 for his kit, Then you need a Alternator, I used a Alternator. e-mail Don for a current quote.

Nippon Denso 50 amp Alternator w/ internal voltage regulator for a

"1993 Geo Metro". Alternator puts out about 14.3 volts at 1500rpm(my originalGenerator put 14.3volts at 2500rpm)Generator put out at a higher rpm in compared to Alternators. Can be rebuilt with new brushes for about $20.00.

I think the Alternator from Napa was about $180.00 + core charge $50.00 so figure around $250.00 this inclues the little bit of wire you have to buy to wire direct to the battery, and a belt to drive the alternator. I also put a real small digital LED volt gauge this is optional $25.00

so about $425.00 I think my Napa dealer gave me a bit of a discount. You have to explain to him that you are converting your bike to all Napa repair and maintenance parts. they may give you a discount like they did me.

Thanks for the info westgl. Will that give me more power to run extra lights? I put light racks on back of my bike and two small driving lights on front but hooked them up to switchs so I can turn them on and off as I want.

Yes, you should be able to.

What wattages did you add/change?

Original is 360watt for a 1986 GL1200-Interstate.

I put a brighter headlight, 4 additional running lights 2 each side front and rear on mine. Two extra tail lights. Then I put two extra 55watt driving lights, you can see that just the extra driving lights alone is 110watts additional. It is easy to use up that original 360watts fast.

To figure your new wattage take your Voltage x Amps

Mine is 14.3volts x 50Amps =715 watts

Not to bad, just about doubled my wattage from stock, another plus is that the voltage is made at a lower rpm of only 1500 rpm (2500rpm for 14.3volts with stock)

NICE ! ! ! !

For me this conversion is a must have, that and the Spin-on Oil filter adaptor from randakk

Glad to see others have used the DT Alternator kit also. I installed the kit over the last couple weekends on an 86 Aspencade, and although the instructions are a little vague was able to get the kit fully installed and the bike running. The guys from DT were very helpful with a couple calls I made to them. And I am in no way a mechanic. I could do it from scratch again in a couple hours.

I am having trouble with the timimg. I have the crankshaft in the lined up position "T" straight on its mark, and both camshaft pulleys in the straight up position. The bike starts but will not even idle, plus alot of backfiring.

Any ideas or pointers anyone could give me. In the process of putting the kit on, I had to flip the right side cam pulley as it was on 'backwards', this allowed the new alternator pulley to fit into the keyway. This made me have to remove that belt and reinstall. Does that belt have to go on a certain way? No one locally will look at it for less than $200. I am in Northern Cal, any one know someone who knows enough to just set the timimg outside of a shop?

It is interesting to read the comments here. I am glad there are choices
when is comes to conversion kits. I chose the Dupli-Tech kit over the Poor Boy simply because the major moving parts are encased rather then in the open so to speak. Now I'm not posting this to degrade one sytem or the other. But just to give you my thought process in selecting the Dupli-Tech over the Poor Boy. Both systems have their good points and their downsides. Both have compromises, but both are way better then the poorly designed factory system.

The alternator on my Dupli-tech install does not stick out any further the radiator, well maybe a 1/2 inch or so. Granted, I will not win any "best of show" with the bikes that I have installed the kit on (two 84I's). I won't be entering any shows anyway. I just want to ride.

To some, the cost and the alternator location are the downsides of the DT system. You make a good point and I fully respect your opinion. A third area is the exposure of the back side of the alternator. The cost and location doesn't concern me as much as the exposure to the elements. I am working on a design for a protective sheild, as it were, to reduce the exposure. We'll see how it goes.

As for the Poor Boy....It is a great system also. But as you think the design through, you will see the compromises. I will leave that to you. This is not a criticism, just an observation.

Bottom line....both are excellant attempts at circumventing a factory flaw in order to keep us ridin' and a smile on our faces.

Peace!

Guys. I wonder if your -comment would change if that unit was a supercharger instead of an altenator. We have all seen and heard the phrase " to each his own". Well I think that fits here. I think that idea is a good one but like so many I prefer Don's. And that is what I have got.: clapper:
