It also depends how good the original case are, it looks like both the early NSR (r2jmc18) and NF5 RS cases start out as the same casing, opening up the top transfers (stock on the left, modded on the right in the above pic) is one of the mods that is done to the RS cases.

You ever back to back test modded vs stock cases them Matt with no other changes?

I know Mark Jordan reckons case work on his KR1S racebike is worth nearly 6 bhp
