Are the carb companies still making parts for them?
I was mildly surprised when reading online that Amal carburetors still makes all parts up to new carbs for the 50's -70's British bikes.
I remember back in the day I had a 650 BSA so read as much as possible about the workings of English bikes. I remember one had a quote about Amal carburetors that I still remember. "You can get more horsepower out of an Amal than any other similar size carb, it is like a gas soaked rag in a two inch downspout." Jim.
