Here's the box I ordered Larry.

TCI Replacement 2020 It Works
- Thread starter Team Junk
- Start date
Well, FWIW, there is no reason I can think of why this shouldn’t work - as long as the amount of advance is about right - and again, I can’t see why it would be all that different from an XS650.
I think I’ll upgrade this thread to:

i think they compared advances and it was the same or very close. so it's very do-able. they may have to use a gn250 pickup and gn250-like magnet poked into a gn250-like position, but at least if they do that it should work fine. if they do have to mount a gn250 pickup, it should be adjustable a few degrees in both directions
Magnet Neo magnet much more powerful than the stock magnet.
Pickup I'm using a Honda scooter pickup (stator and pickup $7.50 at the smiling retailer) in the simulator and the waveform on the scope matches the stcock TCI and pickup. We are experimenting with a Honda pickup to fit in the stator housing.
Placement will go where the stock pickup idle pickup is located.

You running the stock coil?
Good progress Jim
. You deserve the .
I had a few brain farts bouncing around:

- Perhaps the copper could take the form of a press fit sleeve around the magnet - Then drill hole to size of sleeve??
- Upload a full scale graphic of 160 Degree protractor with a dot to align with the timing mark and a dot/hole at 150 Degree for drilling - Interested parties then print image and glue to cardboard and cut out - coloring in would be optional..
- Slot the holes in the inductive pickup to allow for a couple of degrees fine adjustment - could offset errors in drilling.

So I've only been kind halfway following this thread and someone might have already mentioned it, but what do you all think about adding a second pick up and box to run a 277/270 re-phased motor?
See post #54 on.

Would I de-rail this whole thing if I said I could re-build the stock TCI boxes for like $20?
Think I got a couple O dead ones.
You offering that as a service?

fixing electronics can be very frustrating -- not the fixing per se, but what happens alongside. for example there's nothing wrong with the box but the user can't hook it up right. or the box was broken but the user can't hook it up. or the box was broken and the user immediately breaks it again...

Yeah, I get that. At this point, all I could do is say I've replaced parts. I don't really feel like tearing my bike apart to check a bunch of boxes.
Maybe I could eventually work up a bench-test simulator rig, but, like everyone else, I have a day job, a kid, a wife, and still wanna ride motorcycles. ;-)
Most likely failure on these TCI boxes is old capacitors drying out and old diodes failing. Pretty sure the chips are solid, and everything else. I'd say that's about 90% of the "failures" out there. Those aren't hard to swap out on a through-hole PCB, so long as the solder pads don't start lifting.

Ok, I looked back through the posts and saw the rephase details. Once you get a 180 bike up and running we can talk.
yep to all of above. but you can do this with them -- unplug the connector and hang the tci being tested in your left saddlebag. don't really have to tear much apart to road test a tci
