[CALVIN]

I asked on the CRF 100 forum and received a response to sent a pm to a frequent modder, but no reply so...

I'm installing BBR BIG Bore kits on two crf 100's. The CRF Only review of the kit said the reviewer planned to rejet, add a rev box, open the air box etc., but i find no follow up articles.

Anyone with advice on how to get the most out of adding this kit?

Thanks!
