The information about the engine and all other Novarossi engines available in Japan you can find them at:
www.mugenseiki.com web page, but you have to click on the Japanese version of it, when you're in, then click on the left menu on Novarossi, then on the first of three options (for 2.1cc engines). If you have altavista search engine you can have a translation to english of the web page. Have fun.
With respect to info on the results of the JRMCA, got them navigating on several pages, including Novarossi's web page.
