Just one scratch in a jet can alter flow rates- it has been noted on these forums before..
They are not expensive and you know exactly what size you are putting in.
When you change MJ jet you may be looking at avery small range of sizes eg: 165/168/170/172 are in common use on the WR 450.
Each is noticeably different on the bike and I doubt you be able to get the accuracy required by drilling compared to OEM unless you have access to right machine tools - then you may have a chance.
