Update on the LC-1 on my 2001 R1150 GS:
The fuel injectors I had sent off for cleaning (RC Engineering) came back today. The report showed they had flow rates of 315 and 294 cc/min before cleaning; and 321 and 319 cc/min respectively after cleaning. The 21 cc/min difference between cylinders before cleaning seems like a lot, which I believe could account for the slight surge I still had after installing the RC-1.
So I installed the cleaned injectors and went for a ride, syncing the TBs after the engine was fully warmed up. The surging is now gone! I had forgotten just how smooth and torquey the GS is with the richer fueling. The LC-1 transformed the bike. I rode like a hooligan coming home – big smile on my face, 30 degree weather notwithstanding.
Thanks Roger for your help every step of the way. For me, this is a modification well worth doing.
