So I’ve moved on from the TPS to exup
Stripped it all down and cleaned/greased it.
Having put it all back together I started her up and could see that the valve moves about 45 degrees clockwise and stays there whatever the revs. When I switch the engine off it stays at the same position. Switching the ignition on will cause the valve to reset to the correct position over the hole.
I’m sure I’ve got the cables the same way round as before (black outer at the bottom - I might try to swap them over to check anyway) and the valve rotates fully without the cables attached.
Looking on YouTube it seems the valve is continually moving in line with engine revs.
One odd thing I noticed is that with the ignition on but the engine off, I can hear the servo motor under the tank crackling intermittently (hunting?). It’s a very quiet noise and to be truthful Ive heard it before and just put it down to it being held in the correct position. Obviously I cant hear it with the engine on and there is no smell of burning.
Just thought - Could I have messed up on the TPS setting and that’s causing the Exup to have a paddy??
