    Hi.

    I just bought myself a XJ550 -83 4v8 bike and I'm wondering if parts for a -83 Seca would fit?

    Just to be clear I tried to google and also check the forum, but I really didn't get any wiser.

    The reason I ask is that most parts on eBay is either Seca or Maxim, and from what I found on the forum (see attached file), the 4v8 is more like the Seca than the Maxim.

    Could that be a fair point? Does like the carburetors, engine, gearbox, electrical scheme etc. works on either bike?

    Thanks a lot of the help!

    A new but excited XJ550 owner :)

    The 4V8 is very similar to the North American XJ550R Seca models, but it has some extra features that the North American models did not (and should have!), such as:

    - oil cooler
    - dual front disc brakes
    - standing handles on both sides
    - pass/flash high beam switch
    - different wheels
    - and probably a few other goodies

    Most of the XJ550R Seca parts will fit, especially as it pertains to engine and bodywork. Front forks are different, of course, as well as front brakes.

    Awesome, thank you very much that easies thing up a bit, and makes sense with the parts you mentioned :)

    Do you guys also know if there is any big difference between say -81 -82 and -83 Seca models? And -81, -82 and -83 models? A lot of things on eBay is year specific, however, some initial checking seems like the parts are the same.

    Thanks again, highly appreciated :)

    Besides bodywork colors, there's nothing (that I can think of) that's really unique between 1981-83 models.

    Does anyone know by chance where to find a service manual

    I found this site that had real good drawings of all the different areas, but no real 'guidance' on how to for example change oil, service carbs etc.

    Found a thread on XJ Bikes: that states: "HCP1094 Clymer SERVICE-REPAIR-WORKSHOP MANUAL for all 1981-83 XJ550 and 1984-92 FJ600/XJ600 models"

    ---

    Is this indeed the correct book on Amazon? (See attached file, I was not allowed to post a Amazon link).

    I'm just thinking since there are differences with for example Maxim/Seca and 4V8.

    Thanks!

    Also.. Many of the parts listed as 'Seca' on European ebay for exmaple probably are just 4V8 Euro model anyway. Peopel us the word to distinguish them form imported Maxims of which there are
    surprisingly quite a few. Apart form the camshafts I beleive most Maxim engine parts are also common, only the running gear and instruments are different... probably.
