Strewth. That loom is a mess! It's hard to say what goes where as the loom has been hacked about so much.

The blue wire should connect to the tab at the bottom of the holder. The white wire should be connected to one of the filaments in the bulb.

Got the blue and the white in the right position now had a look at bulb holder and a bit of the original wire was left just got the 3 tabs on the white bit to fiqure out where the black wire goes lol

Black wire? As far as I'm aware, there shouldn't be a black wire. If your bike (Extrema) is anything like the 99-05 machines, one bulb is for dip and the other is for main beam. Therefore, each bulb should have two wires. It could mean somebody had bodged a third onto the other filament.

No mate its the older shape only one bulb dual filament and a side light bulb changed model and headlight shape 99 mines a 98

Rare! Nice RS Luke.

02-16-2015, 04:31 PM
Right. I just need to get this clear in my mind. Have you got the rectangular headlight with a single headlight bulb?

02-16-2015, 04:34 PM
It's more oval but still has a single headlight bulb and I'm seriously thinking off selling it now due to lack of parts or swapping for a 99-05 rs50 lol

02-16-2015, 05:05 PM
I'll post a picture up when I go round my mates the bikes in his shed lol there's one in racing planet USA for $99.99 I'll Post that up for.a rough idea

Right, I'm with you now. Yup, that's the correct headlight for the bike. I had to look it up elsewhere as I had always thought the Extrema had two bulbs and not one (You learn something new every day).

It's now obvious that three wires go to the bulb holder. I reckon that it'll be Black. White and blue. Here's the problem. Since your loom has been hacked about. It's tricky to say which colour wire does what. By looking at the other wires in your picture. I'd say that the blue wire is the Earth. While the black and white wires are for the two filaments.

Don't get rid of the bike just yet. Help is at hand.

I'll put a picture up or the original wires left on the connector and maybe I'll get somewhere lol

Got the blue and white wires to the filament (belive to be original and the other blue and orange to the side light (also original but the black wire is really puzzling me as I have 3 tabs to connect to but only 1 original wire left

02-17-2015, 01:59 AM
Having examind the photo's. I can now say (with confidence) that wiring should be as follows:

Blue: Earth
Yellow: Side light
White: Main beam
Black: Dip beam

Your blue wire on the headlight bulb is in the wrong place. It should be on the tab that's currently covered in solder. The black wire should be in that position. I suspect that a previous owner (and bodge artist) has cut the black wire and pushed the blue wire through the hole. Then they jammed the bulb in the holder so the blue wire touches the side of the bulb. It is fixable. It depends if you're handy with a soldering iron though. Either that, or you need another bulb holder.

I'll take it all down my mates later and have a good couple hours with the bike and I'll let you know mate

02-17-2015, 08:27 AM
Wooo hooo one working rs50 head light lol thanks spudgun had a play with the wires and now it's working mint lol next question is how do I adjust the chain on these things there doesn't seem to be an adjuster lol

02-17-2015, 12:38 PM
I've no idea.

02-18-2015, 05:52 AM
Lol this bike seems to of been built to be the most awkward bike to work on lol ill fiqure it out anyway wheels coming off soon so I can check how to adjust and fit new rear pads

02-18-2015, 11:55 AM
There are things about the RS50 I don't like. As you say. They can be awkward to work on. Even something simple like changing a spark plug is a pain. However, things can be made simpler with a few tricks.

02-19-2015, 02:03 PM
Yeah true only problem is I'm still to learn those tricks never really had a sports style bike always had supermoto gsm rx smt rcr and mx so lots of space to work these sports style have tiny space on which you can work lol
