Do a search on this site for DrS' 10 page build thread, contains a load of very good info. My three page thread is not so informative as I outsourced so much of the work!
Fantastic bike! Inspiration for my own build.
I've been using these threads for info/inspiration for my own RC100 S build currently underway. Rich's site in his signature is invaluable too.
Currently at the same stage as yourself - don't know the frame# yet as it's under a thick powdercoat grey, but now have all parts except the yellow toestraps to complete (Burkeredh had already done most of this when I bought it from him though!). Now has the original RC30 '531' legs ( thanks to Robmac ) along with RC35's as well, so can be interchanged between both options.
Got to get the rear wheel re-dished to suit the asymetric rear stays, anodise the fork crown, paint/graphic/reassemble and photograph and I'll be there! If only it was that easy! Watching with interest on this one- hopefully your progress will give me the 'kick up the arse' I need to get mine done!
Hopefully I can add to the advice from those who already have some great examples of RC100.
