    A 5G2 - 10 would be the right TCI unit for your bike.

    OK I gave myself a kick in the butt (sometimes I'm lazy on saturday mornings)and had a look at the parts diagram. It seems that the proper TCI unit for my '83 Maxim 750 is the 5G2.

    Actually, the 5G2 unit is shared by the following models and years:

    '82-84 Maxim 650
    '81 to '83 Seca 750
    '82-83 Maxim 750

    As for the 4H7 TCI unit, it is shared by these:

    '80-81 Maxim 650
    '82 Seca 650

    They also list a 5V2 TCI unit for these last models and years, don't know why.

    Hope this would help.

    Excellent wrap-up, indeed.

    I don't understand at all what all of these advance numbers could mean, though. Could it be enough to make a '83 Maxim 750 run very rough if you put a 4H7 unit while a 5G2 is the right one?

    I can't remember exactly which one I put in, only thing I remember is that I was told it would run ok, but it didn't. This said, there are plenty of things that could be wrong except the TCI (compression not tested, valves not set, carbs not balanced), but it would be a good start to put the right TCI in.

    The advance is telling you when the spark fires in degrees of crank rotation before TDC. Having the wrong advance curve will definitely affect how well the engine runs as spark advance is dependent on the valve timing of the engine. While it is possible to run with spark timing that is different than stock (sometimes it's preferable, depending on the engine), if you get too far off the engine will run very poorly. If it were my bike I'd get the mechanicals done first before trying another TCI. Fix the things that you know are not set correctly before messing with anything else; eliminate the known variables.

    K-moe, Your right permissiontoland advertised and I purchased, as he has more units others may wish to contact him? If he can send it to the UK then and it is as described. I will bump the thread for him. :)

    One good turn deserves another!

    the tci for the 550 650 and 750 will start any of the xjs 80 to 83 but your bike will not run properly without the correct tci
    you need a tci for a 550 ? what do you consider a reasonable price?

    Im coming to find out how hard they are to come by and so i honestly dont want to offend u and low ball you. Im a biker and really just love the ride, the freedom and on this bike the balls she has for being a 550. If u dont think my 550 would run right with a 650 TCI can u explain your reasoning? Cause you have 650 TCI right?

    I have the 550 tci and a few 650/750 tcis
    the timing is different on the 550 than the 650/750. we had a member using a 900 tci for his 550 and switched to 550 his problems were solved.
    the 550 parts in general are becoming harder to find on ebay even new parts needed parts

    ebay selling tci for 80$ my near by parts yard 160$

    place an ad in our wanted forum you will get some decent replies

    Yep that sounds like the one that was in this bike. The blue is what i know. Now that seem like a pretty huge advance considering my knowledge on the HEI im trying which i believe only has a 17 - 36 degree curve.

    $80 sounds fair but i am skeptical purchasing used electronic on ebay. My whole purpose of joining this group is for knowledge and a bwtter sence of reliability in everything. See i would have felt dumb offering you $25. If you would sell me it i wouldnt have the money for a little while but if u hold on to it i will be buying it bfore too long
