New Baffles, need to re-jet?

A buddy of mine just offered to sell me his Big City thunder monster baffles that he had on his R* for cheap. I've got K&N intake, and cobra long shots on the bike right now. If i take the cobra baffles out and put in the BCT baffles will I need to re-jet? Thanks in advance for the info.

No, you won't need to re-jet, and it's unlikely you'll even need to make adjustments to the PMS...but it's possible you may need to adjust it a bit.

If the bike has been jetted for the exhaust and air intake that are on it already [it wouldn't be running well if it hasn't]. A change from one fairly non restrictive baffle to another shouldn't cause enough difference in gas flow to require re-jetting. I went from strait throughs to quiet baffles on my V&H Strait shots on my roadstar and noticed no change.
