Now I have put together a 125cc motor and put that on the utility base as I didn't have all the parts for the 160cc motor , now it goes well and is almost complete, plenty of power. AussieTrev gave me a couple of siesed 125 motors and I managed to soak the bores and pistons in molasses and it lifted the rust off, making it easier to take the piston and rings off. Here are a couple of pics, the barrel in 1969, here's the seriel no . cheers speedy
