Being Stateside you will have the short needle carb (if you bought your motor from a US distributor). Are we talking lean bog out of the corners or just flat performance. The half tank or below lean bog would normally be rectified by the LSN on the shorter needle carb, and any flatness on the top end by the HSN. Unless you are really lean on the top end, then this could cause some bottom end bog too.
If it's always occuring below half a tank, I would first check your tank for leaks around the mid point seam, or is it only happeniing with the GO ?
