i see lol.
i was hoping to get a rough idea so i can get it running and half set up so i can drive it tuned. i cant afford hours on the rollers etc. i know how to get them in sync, im just not sure on how you go about jet sizing etc.

quick googling came up with this (http://www.bmwe21.net/forum/viewtopic.php?p=80216&sid=9cf7e412d34006f1815d487f6717b9ec) it might be of use
