Is 85W coil available?

Post by Juke22 »

Hello,

I'm converting my 2000 bike to street legal, and I would like to keep it AC if possible. I'm willing to do everything possible to avoid DC.

I can't quite recall, but i think the hi beam filament is 30w, and taillight is 10w. I got a brake light off a WR that i think is 21w. the blinkers will be about 10w, and horn is 18w?

that'll be around 85w.

Please correct me where i'm wrong. Will it be possible to run street legal on AC power? Are the 85w coils still for sale?

thanks for any insights.

It is 85 watts at high RPM, not idle at a traffic light.

Ricky Stator used to sell them.

Thats where I got mine. Illinois requires an electric horn, most of which are DC. For this, I put a small rechargeable battery in the air box. So long as I check the charge before going for a street ride, works just fine.

Ah KDXGarage, i totally did not think how hard this would be to convert. None of the kits seem to exist anymore, so i'm trying my best... is it possible to run street legal on AC only? Maybe if i don't use the horn, and run low-beam headlight.

So you only needed battery for the horn? Everything else runs off your 85w stator? is it fully kitted with street legal lights? thanks.

It's not hard at all to convert it to street legal, and it's best to piece together your own kit.
The problem is, to be street legal, you need a DC system.
To be completely legal, you need the DC system to be charged by the bike (not just a removable battery that you can take in your house when you're done riding and recharge and then plug back in), so that eliminates having a rechargeable power tool battery etc to power your horn, headlight, brake light, tail light etc

To be street legal and legitimate, if the bike stalls, the headlight and tail light have to stay on, and the horn has to remain operable as well when the bike is not running but ignition switch or light switch turned on.

Not converting to DC is such a hassle because your lighting will be severely compromised since you won't be able to run an LED headlight on DC, & LED lights always have to run on DC. They "can run on AC," but not very well, and not for any reasonable life expectancy, and with diminished output that negates any benefit of running an LED.

With a rather simple DC conversion, you end up with significantly higher output lighting that works extremely well off-road and have additional capacity left to charge a helmet mounted remote battery pack light, which makes night riding in the woods amazing as you can see not only where your bike is steering towards, but also where your head is turned towards.

I suppose if you absolutely never ride at night or anywhere within an hour or two prior to sunset (in case of any emergency situations that leave you out past your planned return), you can be totally fine with lower powered lighting with inadequate lumens for actual night riding, and ride extremely slow and cautiously and on the shoulder of the road, but why? It's very simple to convert to DC.

If you're adding an aftermarket stator, there's even less additional wiring work required to go DC. Instead of grounding one of two stator leads to the chassis, you run both of them directly to the regulator rectifier and get rid of your stock voltage regulator. Then for any lighting, horn, etc, you run a ground wire insulated back to the output of the regulator rectifier. It's very simple. I'm not sure what your hangup is, but once you learn how to do it, you will understand how simple it is.

I would also like to finish converting my 220H to street legal. I just don't know what I'm doing. A list of parts needed would be great. I have a Tusk conversion kit, but can't figure out my front light bulb situation. I have most of the kit installed. I have a 85w lighting coil & source coil from Ricky stator, but they are not installed. I can afford to buy whatever I need. I just don't know what I need.
If you lend someone $20, and never see that person again, it was probably worth it.

Where can I purchase a "regulator rectifier" to get rid of my stock voltage regulator? I have no idea what I'm looking for.

Just google REGULATOR RECTIFIER FOR MOTORCYCLE. Lots of offerings. Trailtech has them for $30 and up. Give them a call. I found them most helpful when I was hooking up one of their electronic speedometers.

Be sure to check YOUR state to see what is required. Each state may have unique requirements.

Would this regulator rectifier work?

Recommend contacting TrailTech direct. Use the contact page on their website www.trailtech.net. Or try phoning 844 378 8143.

I've found TrailTech tech support very helpful. None of this offshore call center nonsense.

My first bike was a DRZ400s, so i have an OK idea of how the DC system works. I thought AC would be easier, but i guess i'm wrong..

Can I power everything on a small lithium battery pack or do i need a motorcycle battery?

Do i still need the 85w stator if I go DC?

Is there a sticky thread for converting?

thanks

Did you look up what your state requires?

Few states allow one to turn an off-road bike into a street legal bike.

I would be able to use Dirt Legal here in Kansas. People in the nieghborhood have been doing it fot some time now.

Yeah Utah, needs to follow all the street bike requirements.

Juke, Molly's, anyone else that wants to convert from AC illumination system to DC battery charging & illumination system:

Bufftester provided a fantastic set of diagrams & notes for achieving this in 2015. See this forum thread:
