1978 bone stock Super Sport, stock pipes, stock airbox, but Cycle X ignition (just installed). After cleaning the carbs it developed a problem with sooty spark plugs. I got a lot of good advice from the Forum, mostly from Dirt Digger. Charging system good. However, I assumed that the jets were stock 105's. The PO had changed them to 115's for some reason. It runs OK but not great, accelerates hard (thanks Cycle X), and sputters a very tiny bit at steady speed. I have a set of 105 and 110 on order. Do you think that will make a big difference? Start with the 110's or just go to the 105's?
