Does anyone know what size the thread is on a busa's oil presure switch? I'm trying to get the bit's together to fit a mechanical gauge and need to get a suitable T piece. While i'm here where is best to put an oil temp sender? At the moment i'm thinking it's going to be best located through the side of the billet sump. Any problems with this?

Anyone know?

My temp and pressure senders are taken from a sandwich plate at the oil filter.

I think the thread size is 10mm....but it would be safer to check!

I didn't know you could get a sandwich plate for the hayabusa. Where did you get it from please?

I bought one off ebay and then got a bolt/nut bit made up to suit.

Didnt explain that to well! There is a machined thread that holds the plate in place and that you screw the filter to. Had to get this made. Unfortunately I don't have any pics!
