Engine stops when engaging 1st

[Sannox]

Heard that too Trebus but never tried it :-) drained the oil and whipped off the cover, the clutch plates are not stuck, so at a loss, the clutch switch is fine, checked that back at the main connector block under the tank, the side stand switch is also fine, checked that at the plug behind the LH cover, clutch is adjusted ok, the only thing that's a little confusing is when the bike is on it's stand, engine off, select 1st and try and rotate the back wheel, pulling in the clutch lever seems to make no difference, which suggests the clutch....
