    5N9 isn't listed in the manual that i got the specs from, closest is only 5N8 ('82 650J).
    Maybe in 83/84 (for the motor) they used a 650 top end and 750 lower.
    Clearing out old stock and mix and match, like my 750(RL) in a 900 frame.
    As for Wizards 2200cm3 stamp thats seems odd compared to specs, but i just stafrting to learn about these bikes, and haven't see any other in person other than my bike.

    5N9 is the frame code and model number for a 1982-84 XJ650 Maxim, Canadian model.

    With the last 6-digits of the vin (xxxxxx) we can determine which year it actually is.

    Also, the 650 Maxim grab bars are one piece, not a 3-piece design like on the XJ750 Maxim models.

    do you know if a grab rail from a 750 would fit? i wonder if they are the same width? i have 750 rails i think but im missing the rear third of it.

    Why would you want to buy another 750 grabrail,as you already know that it isn't the proper part? Yes,you are missing the rubber covered loop that connects the two sides of your grab rail,but even if it were present,it would do nothing to solve your seat locking dilemma.I am not trying to insult you,just trying to help you find the most sensible and cost effective solution to your problem.And I am still jealous that you have a 7.5 in a 6.5 frame!

    danno,

    i dont really understand what the proper fix is to my seat problem. Im assuming that you were going to send me a pm pertaining to this based on your previous message. however, i didnt get one so i dont understand what the safest way to resolve my seat issue is.

    and im glad your jealous. :lol: :

    truth be told, ive never ridden a motorcycle. not even this one. Tomorrow i begin my motorcycle safety certification course. im a little freaked out by how powerful this bike has the potential to be. I guess its good to have some headroom.

    right now im just waiting on new carb hardware to show up. i got the tank smoothed and primed and im just waiting for it to harden to smooth sand and shoot the final coats.

    Im really excited to have scored this bike. the following here in this forum is great. I dig this bike because its totally different. and now that its a frankenbike i dig it even more.

    thanks for all your help.

    now to hijack my own thread,

    any idea why my transmission would shift backwards? it goes one up 5 down instead of 1 down five up.

    my friend got it up to third while when he was test driving it. and said that it shifted fine but it did it backwards. the seller told me about this. it sounds like something is flipped over, zigged instead of zagged. right?

    Hey,TJ,not the first time a pm hasn't gone through! A grabrail from any 650 Maxim (with a seat lock assembly and key) will rectify your situation. I have all available for $25 plus shipping. (sorry Rick,this was my initial offer,even if my pm didn't go through.).Don't pm me,rather contact me at rukittenme@yahoo.com,if interested. Sorry for the confusion.

    Hey again,turtlejoint.If memory serves correctly,the 750 Maxim shift shaft is in a different location than the 650 Maxim shift shaft (probably to accomodate the 750's adjustable footpeg assembly).The difference in location is slight,and my best guess would be that you are shifting from the other side of the shaft (not that there's any thing wrong with that...)
    If it bothers you,I am quite sure that you could that you could swap your trans cover and shift shaft (a very simple procedure,although I would recommend a new cover gasket and shaft seal,as long as you are in there).If you want to swap yo stuff for me stuff,I can bring you back to the original shift pattern. I kind of like the 1-up,4-down shift pattern as a theft deterrent (As if I need need one ,as much of a beotch as my bike is to start !).

    I think you'd really need the entire internal shifter mechanism, too, as the shaft assembly inside the cover exits the cover in a different loccation (due to that adjustable shifter that Danno mentioned, as the the 650 frame doesn't have the mounting bosses for the adjustable assembly, so they probably used a staright 650 shifter pedal on a 750 engine, and that will give you a reversed "pattern"). It's not as quite as simple as merely substituting the COVER, as the shifter shaft and lever assembly are different also, and perhaps some of the other internal components.

    Some additional advice on what other issues you might run into might be needed,
