Hi all, I have been doing some research lately and it seems the 91 - 92 B400's have different cams. After looking through the service manual it looks as if the 93 cams give less valve lift (not sure on duration). Has anyone out there swapped out their '93 cams for earlier ones? Would this swap give any noticeable difference or should i still continue my search for GSXR 400 cams? Hope someone on here can give some advice, thanks guys.
