There is one believe that one screwdriver fits all. They are wrong!
Using a non-suitable screwdriver will make more pressure is needed to turn the screw, this in case make the screwdriver sometimes slips away from the screw head. When this happens, the screw head can be damaged and sometimes up to a point where it can’t be used anymore. This is bad if you original screw set that comes with the bikes. I have once tried to buy original screw for my Yamaha 125Z and it cost me about RM3.oo (USD0.90) per piece!
In the above picture, it is shown a 18-pieces screwdriver set RS brand tool. The Mikuni Super Tuning Manual shown there is printed on A4 paper to give you the idea of the size of the tool set.
Even though I have 18-pieces of the screwdriver, I think I need more than that, maybe another 30 pieces of it with different. Maybe that is just pure indulgence of tools.
