Hi all, I have been scouring these threads for a while now while rebuilding / modifying a 1978 CB550 K4. It had sat for about thirty years when I bought it (for too much), but only has a little under 5k miles on it. So far I have pulled the carbs, de-racked them, completely cleaned and rebuilt them and am happy with the way they turned out. Set them up as best as I could guess for K&N style filters and a 4into1. We will see how well I guessed when I start it for the first time in 30 years here in a week or so. In the middle of several projects: brake MC, tank coating (aftermarket, the original was rusted through), electronic ignition, new clutch plates, etc.
Anyway, I have enjoyed this forum but am at the point where I may need to ask a few questions and post a few photos as opposed to just browsing and searching.
