Dano Posted March 13, 2009 Share #1 Posted March 13, 2009 Finally pulled my TCI out for a "shake and bake", took the cover off and discovered a lot of battery acid fume corrosion from where the PO had taken the vent hose off the battery. That's the reason I had to repaint the frame last year when I did my second gear. Soooo, not sure if the board is affected way down deep in it's recesses, I'm looking for another TCI to fit an '84. Anybody got one they want to part with in good shape? I've got a few days as I also pulled the carbs to clean out.

woz111 Posted March 13, 2009 Share #2 Posted March 13, 2009 Hi Dan, take a look at the track ways, so's long as they are still intact you should be able to repair it. if you can post a picture of it here, I'll have a look at it and tell you what I think? Its a shame you can't buy new pcbs? Link to comment Share on other sites More sharing options...
83VR3711 Posted March 13, 2009 Share #3 Posted March 13, 2009 Hi Dan, I am trying to remove my TCI to inspect it as well. How did you get yours out?? Right now my girl is down to a frame and a pile of wires, but I have yet to figure out how to remove it..... Thanks in advance, 83VR3711 Link to comment Share on other sites More sharing options...
bongobobny Posted March 13, 2009 Share #4 Posted March 13, 2009 Dano, from what I've been told, any year except an '83 will work. I do have 1 spare but I'm afraid I might need it for the '85, and won't know for at least a couple of months for sure. Link to comment Share on other sites More sharing options...
Dano Posted March 13, 2009 Author Share #5 Posted March 13, 2009 Hi Dan, I am trying to remove my TCI to inspect it as well. How did you get yours out?? Right now my girl is down to a frame and a pile of wires, but I have yet to figure out how to remove it..... Thanks in advance, 83VR3711 I just removed the carbs, airbox and battery box. Use a short stubby phillips (#2) screwdriver and you can remove the 2 screws that hold it in. Of course, they're upside down, but it can be done. Yours should be especially easy if you've got the fairing off, you can pull the whole bracket out that the TCI, coils and pressure sensor mounts to. 2 bolts on each side (#10mm) and pull the whole bracket. Good luck, Dan Link to comment Share on other sites More sharing options...
GeorgeS Posted March 13, 2009 Share #6 Posted March 13, 2009 I used a 1/4 Ratchet, and socket with #3 Phillips Apex tip. You can get more torque on the heads that way. Those Screws are tight. Link to comment Share on other sites More sharing options...
painterman67 Posted March 13, 2009 Share #7 Posted March 13, 2009 Dano, from what I've been told, any year except an '83 will work. I do have 1 spare but I'm afraid I might need it for the '85, and won't know for at least a couple of months for sure. make sure of the year. I found out the hard way. Now asw for youryear there are usually a few on ebay. Also pinwall cycle on ebay is a real good plce to start. Mine is a 91 and a 88 wouldn't work in mine only 90-93 . I think 83 -85 but not sure and 86-89. Hope this helps. David Link to comment Share on other sites More sharing options...
Snaggletooth Posted March 13, 2009 Share #8 Posted March 13, 2009 (edited) The '83 TCI is all alone. I ended up with one by accident and tried it. My '84 started and idled fine but I believe it's the advance curve specs that are different. I had the specs on an old post somewhere. If I can find them I'll post them. As a replacement on an '84....won't work for the long run. Edited March 13, 2009 by Snaggletooth Link to comment Share on other sites More sharing options...
Snaggletooth Posted March 13, 2009 Share #9 Posted March 13, 2009 Here are the different specs on '83 and '84 TCI's These specs are from the original spec sheets I found. 26H is from an 83. 5*@1000 rpm and 32*@7000 rpm. 41R is from an 84. 5*@1000 rpm and 32*@4500 rpm.

Dano Posted March 13, 2009 Author Share #10 Posted March 13, 2009 I am aware of the difference. The 83 pulls its vacuum for the timing (pressure) sensor from above the butterfly in the carb, 84 to 89 uses the same TCI (vacuum pulled below the butterfly). I believe the 90-93 uses a different profile for timing. Thanks for the input, tho. Dan Link to comment Share on other sites More sharing options...
muffinman Posted March 13, 2009 Share #11 Posted March 13, 2009 Check Pinwall on ebay. Jeff Link to comment Share on other sites More sharing options...
Dano Posted March 14, 2009 Author Share #12 Posted March 14, 2009 Pinwall is 300 bucks with shipping. WIth no side jobs and 200 bucks a month extra gone for health insurance increase, guess I'll be doing whatever to bring this one back to standards.

Snaggletooth Posted March 14, 2009 Share #13 Posted March 14, 2009 Take a look at this sight. Not the same but might be some useful info for you on it. http://home.ptd.net/~theragos/index.htm Link to comment Share on other sites More sharing options...

Yammer Dan Posted March 14, 2009 Share #15 Posted March 14, 2009 Didn't we have someone that rebuilds them?? Link to comment Share on other sites More sharing options...
Dano Posted March 14, 2009 Author Share #16 Posted March 14, 2009 Spent 2 hours last night here at the "electronics" work bench, cleaned all the corrosion off(totally removed the board from the housing-ouch!!), put it back in and re-soldered the connections. Some of the circuit board slots didn't fair very well from the removal, but I've managed to get them all soldered back together. Checked ohms from the terminals to points on the board and had an average of .1 Ohms across them. Now I'm looking for the terminal point diagram on here so I can check pin to pin resistance. If someone could help me finding that, I would appreciate it! Carbs later on today after some BBQ for lunch! Thanks again guys, Dan Link to comment Share on other sites More sharing options...

woz111 Posted March 14, 2009 Share #18 Posted March 14, 2009 Hi all, I have rebuilt two units and both work fine, if anyone's got some non-functional TCI units please send them to me stating the year of the bike and I'll see if I can repair them, like I stated though, if the pcb boards too damaged, trackways burned etc then there's not much that can be done:178: Link to comment Share on other sites More sharing options...
Yammer Dan Posted March 14, 2009 Share #19 Posted March 14, 2009 Frogman is very good when it comes to this stuff. I get lost trying to follow his directions. Electricity and I don't get along. I have my extra TCI on "Ugly" now. First time I washed her when I got her with just water hose I couldn't get her to start again. Still got to get in there and take old one out.

Rocket Posted March 14, 2009 Share #20 Posted March 14, 2009 Didn't we have someone that rebuilds them?? I think it was DonB, that did that. But he was burned by a new member & was having trouble, getting some replacement components. So he may have stopped, doing this service for us. BTW has any one seen him on the site lately????

Turns out his setup only deals with the 83-89 tci boxes. David Link to comment Share on other sites More sharing options...
Fvogt Posted March 14, 2009 Share #22 Posted March 14, 2009 1983 - 89 are analog & 90-93 are digital so the pickup at the flywheel and the wiring are different. Fred Link to comment Share on other sites More sharing options...
Dano Posted March 14, 2009 Author Share #23 Posted March 14, 2009 Thanks Freebird. Printed out the diagram for my folder and am getting ready to check it to make sure my solder connections are good. Dan Link to comment Share on other sites More sharing options...
