    Recently bought a non running XJ550 that had an tci failure. tried a spare Honda CB550 Ignitor i had and she fired right up but only idle's.. seems to me either there's no advance timing built in to the tci or if it has it then most likely not compatible with this particular engine. So now i'm thinking of mounting an mechanical advancer on to the pick up coils shaft to make it advance.. I also have a spare CB125 Mech Advancer with counterweights that I can use, if compatible.

    Ideas?

    :)

    Hold-on, man.

    You shouldn't be trying to add Honda Parts and a Mechanical Advancer to your Bike and expect it to suddenly run right.
    You might be doing more harm than good.

    The problem you have is not having the right Igniter.
    Once you get the right YAMAHA - XJ - 550 Igniter ... you'll be back in business.

    Goin' Rube Goldberg and addin'-on stuff ain't going to bring you nothin' but grief!

    I got my spare 550 TCI unit, from a running bike, off eBay for ...are ya ready?... $2. Plus shipping ($8) but who cares! They're out there, I run across 'em all the time for anywhere between $10 and $200. Rick's right, and you can round up the parts easier than fix the problems you might be about to cause yourself.
