Wiring up a wr400

Recommended Posts

I'm looking at getting a wr400 and doing a motard conversion, but I'm a mx guy and I've never messed around with lights and blinkers.

 

There's 2 bikes I'm looking at, one comes with just a headlight, the other comes with a head and tail light.

 

How do I go about wiring in the other parts I need? As far as I can tell all I would need it a horn and blinkers front and rear.

 

As I said, I'm a noob when it comes to electronics, so I'm not even sure where to start.

 

Thanks in advance

I'm assuming the two bikes your looking at are either the 426 or 400 WR's (your previous posts would suggest that).

The main concern you should be looking for in a conversion bike would include:

1. Is there a battery on the bike, and
2. Can the electrical system handle the excess load of street electronics.

With that being said, WR400 stator is 85 Watts (peak), and the 426s put out 130 Watts (peak).  So both would suffice for concern #2.  However both bikes do not have a battery as they are running a AC wiring system so they'd fail on concern #1.  The later WR450 models are easier to convert because for the most part half of the work is already done.. There's already a battery, you can convert the AC side of the bike to DC with a simple stator and voltage regulator conversion, then add a wiring harness like this [url=https://www.bajadesigns.com/products/dual-sport-kit-yamaha-wr250f-wr450f-03-06-no-headlight.asp](BajaDesigns Dual Sport kit)[/url] for all the extra stuff (horn, signals, high/low beam, tail/brake light.)  As I said in a previous reply, they're not really a great bike for street usage, but if you're super keen on pursuing the subject there's lots of reading and topics on the subject.

Here's a specific thread dedicated to the electrical conversion a WR400 to street:

Looks like a bit of an operation.

Why do you need to convert to dc? What's wrong with the stock ac setup?

Yes, it is an involved operation to get a WR street legal.

 

DC relays, LED's, normal bulbs, and switches don't like AC power.

I have a Baja designs kit on my 400, and tusk makes one too. They aren't too complicated if you have a reasonable amount of mechanical aptitude. The BD kit is about 500 bucks but as previously mentioned you have to address the AC/DC issue. Baja Designs have rewrapped stators to address this. My bike doesn't have a battery, but it does have a rechargeable battery pack behind the headlight assembly for a little extra juice at idle.

That being said, it's an awful lot of work and expense for such an old bike. If you go for it make sure your state still allows dirt bikes to be converted for street use. Here in Oregon only grandfathered pre '06 bikes are allowed that aren't factory street legal.
