A stupid question but is the roller bearing damaged and worn? The gearbox on Ratty had over 45k on it (probably over 50k as the PO had fitted a mini Speedo on the bike at some point). When I checked the roller bearings they were fine, no play, no nasty rumbling and no tight spots. The rest of the engine was in a terrible condition as a result of the PO blasting it with a sand gun. The roller bearing was good to go again but unfortunately the shaft was worn beyond repair and I purchased the two gear shafts from Ted. I have no idea how many miles were on that gearbox but again the roller bearings were absolutely fine.

The bearing doesn't feel great, quite gritty when spinning it.

I've tried heating the collar, clamping the bearing and giving the shaft a wack. Not budging at all.

There does seem to be a seal between the bearing and collar. There is no way to remove the gear, the groves are too big for it to slide off the other way, the bearing and collar are holding it on.

That is a standard car bulb and there is an H4 equvalent, i will see if i can find a number for you cos im bored

Bryan,

I first made the mistake of fitting a normal H4 halogen bulb, and found the charging system would not cope well when driving in towns etc.

I have a volt meter fitted and noticed the voltage drop below 11.5 volts when waiting at traffic lights and road junctions.
I switched back to the standard 410 bulb to rectify the problem, but now have an LED which obviously has an even lower power draw.

Thanks Skoti, that looks the best and easiest option.  Mine must be missing a retaining clip or something for there to be an oil seal used to hold the P45T bulb in.

One last question, did you use a 4300k bulb? 6000k might be a bit blue?

Yes, I used the 6000k bulb and it's a bit blue. Maybe the warm white would look a bit better on an old classic motorcycle but that's your choice.

BTW
there should be a spring below the headlamp bulb retaining cup to hold the bulb in place.

« Last post by beardylondon on Today at 07:38:45 PM »
Hi All

So I am starting to get my head round fitting the new coils....

As per photos below, the original wiring is coloured blue and black/white and yellow black/white the other side.

The new ones, as per bottom photo, the wires are solid red and white, so my question is, which way round do the wires go?

thanks in advance!
