I ended up getting a chopper roller w parts, and being familiar with the cb550 thought it would be cool to have a chop as well. Jsst trying to get all the facts on them. Do you happen to know what jet sizes your bike has... Im trying to figure that out as well. I took them apart and they are a #37 and what looks to be a 1.8...? It dosnt seem to make sence...lol
