I just got a 1979 cb750 10th anniversary. So far Ive had the carbs cleaned and changed the oil. Carbs seem a lot smoother. I found some fine metal shavings in the oil filter. The bikes running but the rpms are jumpy, its backfiring, and the #4 cylinder isnt firing, the pipe isnt getting anywhere near as hot as the others. After it runs for a while it starts to run a little smoother. This is my first bike and any help would be greatly be appreciated.
