Got a better copy of the F3 NC30 manual today and it came with these parts manual additional pages:

I translated these pages at the weekend. Seems the gearbox was changed due to changes to the shape of the dowels on the gears, exhaust redesigned for more performance and to meet new regulations and the top rad was increased in size to cope with 4 & 6 hour endurance races.

So it looks as if there where early and late F-3 exhaust's then? Me and Tony compared photos of ours and they where so similar but had slight differences that we could only put down changes to the later systems.

Yeah it appears so I know for the RC30's there were several different HRC exhausts so would figure they did the same for the NC30's too

Bought volume 29 of the racers magazine on ebay last week. Great pics and details on the F3 bikes!

Fancy posting some scans?

I'm not that great with scanning, but take a look over here:

The RCB400 is a strange but great machine!

The rcb was cbr400 based I think? The wheels from my Bluefox cbr have rcb stickers on them so can only assume they were on one before my bike

bloody hell thats expensive, there only 1000 yen in Japan

Yes I paid way too much for it.
Midnight ebay buy...

Yes they are a lot cheaper in Japan but you will have to pay shipping also.
Shipping is free with this seller. Another one is way cheaper and ordered a few last week from him.
I also found this website:

I bought a lot of the Suzuka 8 hour magazines 1994 until 2000)last year through Yahoo but I am still looking for the 80's issues.
