Hey, hey, hey, bikerpsycho came in from work and reminded me that the bike has got a cut out on the stand, if the stand is down and you put the bike in gear, the engine cuts out.
Never had this in 'my day'

you just rode off and if the stand was down it scrapped a bit then folded up, if you did'nt come a cropper first

So we went out, started the bike and put the stand up and guess what, all appears to be well so far, the engine did'nt cut out. So a big thanks for your help Chris. My only excuse is that I had a senior moment
