Check all vacuum hoses are on as they should be, and then take a look at the idle screw which is right next to the throttle cable attachment to the
throttle bodies. Back this right off and see if it changes the idle. Can't think what else it could be. It has to be air getting in from
somewhere.
I think there is a cold start cable somewhere too. Check this is as it should be.
Can't think what else it could be.

Don't pay a garage to do them. You built a car for God's sake - I'm sure you can fit your own wipers!

Seems to be revving really high if the throttle butterflies are closed....must be air entering somewhere...there is a cold start lever on the bodies,
this could be intefering....engine needs fuel to rev that high....

If it is like my '99 Busa there is an idle adjuster knob. Could be that some joker has wound it all the way up?
