Thank you for the welcome!
Both bikes are on the rough side, the 4x4 had been sat outside for a very long time, lots of surface rust and flaking powder coat, dry rotted tyres etc but it really hasn't been hacked about.
I cleaned and rebuilt the carb, went through all electrical connections and cleaned them, put a new fuel petcock on the tank, new oil and filter, new spark plug chucked a battery on it and it fired right up. I need to go through the brakes next.
I haven't spent much time on the 4x2 as I have only had it a couple of days. It is missing a few key parts like the fuel tank, gear selection pedal, cam cover etc.
I will try and post some pics in the next few days.
Thanks again!
