Thanks fior the replies all
Looks like i will be getting my Butt up to Force 4, Been there before, so know where it is. Will be needing some 2 stroke as well, and probably some greases and bits and bobs, so all together can make it a worthwhile journey.
I have ordered the sealing washers and spare plugs, as well as the impellor replacement kit, annodes, lower leg seal kit (if needed) and also a few fuel filters, along with Pikey Daves link on indexing the plugs, Diagnostics kit, and hopefully a manual on the way(maybe) I think I might be able to manage.
Of course if I get completely screwed will ask my kid brother for help, such is the bonus of having a motor mechanic in the family
Having said that he usually works on Landies, so he will probably turn up with a sledge hammer and a crowbar as his tools!
Again thanks all
