Identifying CDI's

Ok so I have been looking at what good/bad bits I have with my bike and I need to identify my CDI........
It has the following numbers on it: 21119-1271 (this is listed on the microfiche on the main site as the part number for the H1 and J1)
and
131800-5240
Can anyone tell me which CDI this is, two reasons.......I need a set of pickups for the engine as they are missing and secondly I dont want a jap restricted box.
Cheers
Jason

im pretty sure 1271 is a jap spec H model cdi, 14,500rpm redline, 180kph speed restrictor. i cant remember off the top of my head which pickup rotor is required for it, but can find out in a couple of days.
uk spec cdi is 1332, usually has a blue sticker with an M on it, gives 14,900rpm limiter and doesnt know what 180 limits are.
there isnt much in it tbh.. if you are racing, get a cdi from BDK, much higher rev limit (~15,500-16,000rpm) and better advance curve.
