Seized Screws

Hi people,having just got some Gilles Vario bars thought i might look at taking the clip-ons off or loosening everything off but the switch screws are not moving at all,would it be easier to get them out when i remove the standard clip-ons or keep trying with them in place,any ideas would be a great help.
many thanks Phil

 

Are you using a JIS screwdriver? If you haven't got one then I think a PZ2 is the closest match to the JIS.

 

deffo dont use a PH, it has a cam that will slip at high torques and screw-up your head

 

Where might i get the proper screwdriver?

 

Most tool suppliers can get them, look for your nearest sealey supplier.

Many other companies make them as well.

 

US PRO 1616 Tools 4 Piece Japanese Industry Standard Screwdriver Set JIS ph1,2,3 https://www.amazon.co.uk/dp/B07W4VXDRV/ref=cm_sw_r_apan_glt_fabc_J94YBRMD0PT9SD62P3XM

These are decent enough for the money.

All cross headed screws on Japanese motorcycles are JIS by the way.

 

just got a PZ2 from screwfix,they still won't budge think i might just have to take the clip ons off then butcher them off and get replacements
