I own a 03 Black 636. The other day on the freeway i noticed a 03 f4i wanting a little action. I was late to meet the fellows so i was already cooking pretty good. He pulled up beside me at about 90 and we rolled from there. I didn't even down shift and it was over from the start. I let off at 155 and he was at least 10 to 15 bikes back. He wouldn't even look when we slowed down. That's what you get.
