Hi b4ort, it’s a dell’orto so not original i think everything on this bike has been suffering from a slow lingering death🥴 it was running ok with the air leaks ‘cos the mixture screw was 3 turns out to compensate possibly, i would love to do a nut an bolt resto(maybe in my old age with one of the grandkids) but i just wanted something that worked to have a bit of fun on, anyway i go back to blighty ina few weeks and the parts are from inmotion so will bring them over with me next year, watch this space it’llbe a 1 year later thread ressurection😂 cheerz mdeerz
