Wizard765 Posted July 25, 2013 #1 Posted July 25, 2013 Just thought I'd pass along the symptoms and see what you guys think. I started a thread about coils but now I'm not as sure about it.. Started some time ago getting not so good mileage but thought it might just be the methanol in the gas around here.. Lately was running rough and missing so I changed the plugs. One of them had some carbon build up on it. After the change it ran better but about two tanks later started doing it again. When the tank was down to about two bars I put in a whole can of seafoam and ran it hard for 1/2 hour then parked it for 2 days. After that it ran better for a while but still not right. Before the Seafoam it would not go above 5500 rpm. Would just sort of flatten out at that. After the Seafoam it is now at 6000 rpm that it flattens out. Sometimes it gets jerky at that rpm like it's catching and not catching etc.. So I was thinking a bad coil but now not sure.. What does the gallery think?
Yammer Dan Posted July 25, 2013 #2 Posted July 25, 2013 Stop at Wally World and give it a can of BerryMan's Chem Tech. A little stronger. Just get tank below 1/2 and run it thru it. It will be close to the Sea-Foam. Carbs been synced?
saddlebum Posted July 25, 2013 #3 Posted July 25, 2013 I think you may be right about the coil. It is not uncommon for a coil that is on its way out to start breaking down at high RPM
Huggy Posted July 25, 2013 #4 Posted July 25, 2013 I'd check the carb sync and I'd run some Stabil through it. The old Harley guy's do it on a regular basis. And they should know, after all they need all the help they can get to keep them on the road! And I do it with my XJ. It will clear out any gummy build up that may have accumulated in the carbs with out having to do a teardown of them. I put in what ever amount is required for storage and away I go.
dysfunctional33 Posted July 25, 2013 #5 Posted July 25, 2013 I am going through a similar issue with my 84 VR. Check your carb sync and make sure your carbs are all seated nicely all the way down in the boots. I found that my #1 and #2 carbs were popped up and not seated all the way. Once I put them into place and got another carb sync done she started running better. I am still waiting to see if its a lasting cure. I do need to sync again though after what I'm pretty sure is sabotage by a psychotic neighbor. I'll post my results next week hopefully...
easternrider Posted July 26, 2013 #6 Posted July 26, 2013 When it acts up, is it right away, or is it after a little driving? Now you say that it will not go over 6000rpm. When you hit that, is it dead on power, but just enough to keep going? Just thought I'd pass along the symptoms and see what you guys think.

Wizard765 Posted July 26, 2013 Author #7 Posted July 26, 2013 Thanks guys: I have an update.. Dismantled the bike to get to the coils and TCI. Got another set of coils with lots less miles on them from a friends parts bike. Had a tough time getting them out of the rack they are on. Eventually they did come loose. His parts bike is an 83 so the TCI is no good to me. The rack on the 83 has all four coils on the same plane so that the two back ones are hard to get at the screws. the 84 has those back ones at a slight angle to the screws are easy to get to. Anyhow coils look good but I decided to have a look at my TCI while it was out. Good thing I did. First I could not figure out how to get the circuit board out. Eventually took it to another friend that is amazing with a soldering iron. He was able to take it apart without any damage and all 8 of the diodes were toast. So I ran down to the local electronics store and bought some diodes ($3.00 including tax) and he put in the new ones for me as well as putting the thing back together. Looks good now and I'm hoping this will solve my problem. Will be reassembling it tomorrow but while I was taking it apart found a couple of broken tabs on the fairing so have to fix that as well before I can test ride it... Should know by Saturday.. I'll keep ya'll posted on the outcome..
paysaw Posted July 26, 2013 #9 Posted July 26, 2013 HI wayne I have 2 TCI units from 84 bikes,One I think is good and one is for parts.Let me know if you have issues.You can use my TCI as a tester.Good luck with her Wayne and post your results. Ray PS . I have 84 coil set too..
Evan Posted July 26, 2013 #10 Posted July 26, 2013 Good luck Wayne!! Glad all this happened before your up coming trip east.
Huggy Posted July 26, 2013 #12 Posted July 26, 2013 Thanks guys: Will be reassembling it tomorrow but while I was taking it apart found a couple of broken tabs on the fairing so have to fix that as well before I can test ride it... Should know by Saturday.. I'll keep ya'll posted on the outcome.. How do you fix your broken tabs? that's something I need to do.
Silverado6x6 Posted July 26, 2013 #13 Posted July 26, 2013 I just removed my 83 tci and replaced the diodes but it was a whipping a dead horse attempt as the eprom probably died a long time ago, bike had been in storage for 17 years, found water in it and when I get the next venture tomorrow an 89 the first thing I do will be to inspect its tci, mod and relocate it.
paysaw Posted July 26, 2013 #14 Posted July 26, 2013 I just did 4600kms on my 84 last week going out east.
easternrider Posted July 26, 2013 #15 Posted July 26, 2013 I just did 4600kms on my 84 last week going out east. And I bet yours was the best bike of the three that went. (inside joke)
paysaw Posted July 26, 2013 #16 Posted July 26, 2013 Oh, thanks for reminding Alex ...LOL.I told Wayne you will be there for him if he needs you...LOL
Wizard765 Posted July 27, 2013 Author #17 Posted July 27, 2013 How do you fix your broken tabs? that's something I need to do. I fix my broken tabs with Plastex or Plastifix.. Bring it over and I'll show you..
Wizard765 Posted July 27, 2013 Author #18 Posted July 27, 2013 Ok I'm officially in Panic Mode now.. I got it back together. Before I put the plastic back on I started it and it ran GREAT. revved up to 7,000 without a problem seemed fine and strong so I put it all back together. Did an oil change etc. fixed my tabs and cracks and this morning took it for a test run.. Now I'm totally messed up. No tack. Running rough (like in 3 cylinders). No power at all. This is way worse than when I started. So my guess is the TCI is pooched. Please confirm??? Does the TCI send the signal to the Tack? I'm suppose to be going on a trip to the East Coast in a week so this puts me in PANIC MODE!! Ray I think I'll take you up on the TCI you have and see if that fixes it.. Thanks everyone for your input..
Huggy Posted July 27, 2013 #19 Posted July 27, 2013 My bike is in NO condition to go anywhere!!!! Its all apart and all over the garage!!!!!
Wizard765 Posted July 27, 2013 Author #20 Posted July 27, 2013 My bike is in NO condition to go anywhere!!!! Its all apart and all over the garage!!!!! Bring something you want to fix over.. should be easy as all the parts are off the bike
Huggy Posted July 27, 2013 #21 Posted July 27, 2013 Bring something you want to fix over.. should be easy as all the parts are off the bike I'll probably take you up on that! As soon as I get to the point where I need to fix things. Like I the left saddle bag has a hole in it. Looks like its been hit or dropped. Also found a crack in the bottom of the trunk. Its had something dropped on it or its been hit with something. I'm going up to Aircraft Spruce in Brantford and see what is best for this looooong crack. Its at the bottom along the back and runs the width of the trunk!! I'll let you know when I can make it and I'll throw it in the car and come over!!!
Wizard765 Posted July 27, 2013 Author #22 Posted July 27, 2013 Richard: If you are going to the Brantford Airport they have a kit of Plastifix. It's around $100 and is what I'm using. You can fix a lot of plastic with this kit and way cheaper than Plastex which I think is the same stuff. Anyhow pick one of those up and I'll be happy to show you how to use it.. GREAT stuff.. Wayne
Squidley Posted July 27, 2013 #23 Posted July 27, 2013 Wayne, The tach is run off #2 cylinder, so it does sound like your TCI is pooched. I dont know if Dingy has any more of the updated Ignitec systems left, but it sounds like your going to need one.
paysaw Posted July 27, 2013 #24 Posted July 27, 2013 I talked to Wayne and I have a couple of 84 TCI units her can try.Also, I am giving him my coil pack for good measure.I hope this helps you Wayne. Ray:080402gudl_prv:
Wizard765 Posted July 27, 2013 Author #25 Posted July 27, 2013 Thanks Ray I appreciate your help. Brad I also appreciate your input which is number two cylinder sitting on the bike
