Like I said, I noticed it on my F7 this last week with all the sub-zero weather. Just cruising along at 50mph at -10F if I punch it, I only get 7600rpm. But like you said, do it two of three times and it revs normal. I think it has to be a cold pipe.Originally posted by schifty@Jan 27 2003, 09:31 PM
no broken springs.
rob- could it be that simple? the pipe stays cool even if i have been running at say 20-30mpr cruising speed and hit it in the open field ?
