New here and looking for some wisdom of the crowd...I’m looking at purchasing a 1977 Honda CB550K w/ 14,000 miles. The seller says it’s in good condition and he has cleaned and replaced all the jets, but it needs some tuning. It looks good in the pictures. Any recommendations on what else I should look for (known issues w/this model/year) when I check it out? He’s asking 2k, does that sound reasonable? Your comments are much appreciated.
