lay down gearbox

Forums

Canada calling. I have just finished assembling a basket case '53 Model 7. In static mode all gears shift up and down nicely, as they should. But in transit the gearbox shifts from 2nd to 4th, missing 3rd. After the ride I put the 7 on the  entre stand and checked the static changing, all ok, then ran the bike on the centre stand and observed the shift from 2nd to 4th. Any suggestions before taking the outer cover off?
