Hi Everyone. First post here...recently acquired a 1972 Gus Kuhn 750 with a Combat engine. Currently having the frame and brackets repainted, but the wheels, tank, seat unit and cycle parts are in pretty good shape, so am just cleaning 53 years years of crud off and putting her back together as she is.
The 32mm Amal carbs were running with bellmouths and are a bit scored, but I am keen to get her back together, get her running later this summer and then if the motor needs sorting I'll get that sorted over the winter. The bike has just 19k on the clock, I don't believe the block has ever been apart, as the nuts at the base of the barrel look untouched. Everything including the fact I am just the 4th keeper points to the fact she's pretty original - oh and a 2 into 1 Dunstall exhaust system too.
I have put a camera inside the bores, l/h pot is fine - r/h pot has a small amount of scoring on one side only, so am inclined to clean up and get her going as is before performing any automotive surgery. Am replacing isolastic rubbers, which have sagged with age, but am v excited to get her up and running. Any thoughts on whether I should go further with the motor at this stage most welcome.
