How can I tell the year of my motor on a cb550?
« on: February 27, 2013, 05:57:25 PM »
Looking at finding out the year of my cb550 motor that I just recently picked up? Is there a way to find this thru the stampings?
Thanks all,
MAtt

 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

No, sorry, don't know what size they are. Bike has run fantastic since the day I got it.

Do a search....
