Im about ready to get my 74 cb550 back on the road after a winter freshen up. But I dont have a carb sync, also it would be nice to know of a good shop, or somebody that could help me with this thing. There is a honda dealer but I went in there once asking if they could help me set my floats on my carbs and they said the carbs had to be on the bike for them to do it. I figured that part out but it doesnt really make me want to go there again.
