look in the wiki
I don't know what the stock jet is, but you could check the spreadsheet (linked on wiki, or search the forums) to see if anyone is running a Derbi with a stock jet -- or, better yet, to see if they have an all-stock bike except with the pipe you're looking at. Generally, when you add performance parts, you upjet (get a larger jet), but you should do a plug chop to verify your jetting once your pipe is installed (also in the wiki).
