I have a GSXR1100W with 46mm Hilborn throttle bodies and Microsquirt ECU. It showed up a weakness in the charging system being able to keep up with the increased current draws, especially at sustained low rpm's. I adapted a 45 amp Triumph alternator to cure the problem.

1299cc race motor with SBM billet block. Ended up producing as much power as with the FCR41's, but with more complexity. I have gone back to the FCR's. Might be better with larger TB's, but you still have to match up to the smaller manifolds on the head. I have kept all the gear and may revisit one day.
