Mrzrex Posted May 16, 2015 Share #1 Posted May 16, 2015 I have a 1983 XVZ1200 and when it rains it starts missing horribly and actually will drop down to one or two cylinders. I barely made it home from work. When it dries out it runs fine ?? Spark plug wires ? I was reading the one post about coil removal and looks to be a nightmare !!! Any suggestions please ???

VanRiver Posted May 17, 2015 Share #3 Posted May 17, 2015 Wet TCI. There are several threads on the subject try the search. Yup @mralex714 nailed it....a total wet TCI. Time to relocate it to the top of your airbag and keep her dry before there is permanent damage. Link to comment Share on other sites More sharing options...
Mrzrex Posted May 17, 2015 Author Share #4 Posted May 17, 2015 What is the TCI any how ?? And that would make it miss terribly ??? Link to comment Share on other sites More sharing options...
Venturous Randy Posted May 17, 2015 Share #5 Posted May 17, 2015 It can also be related to the wiring coming out of the igniters. Get a small can of WD40 and if it starts missing, pull the cover off of the clutch slave(the rubber square cover where you bleed slave) and spray down in the hole area very good. Let it set a minute and go riding. I have had the same problem and my TCI is mounted on the airbox. Randy Link to comment Share on other sites More sharing options...
Mrzrex Posted May 17, 2015 Author Share #6 Posted May 17, 2015 Wait that doesn't seem to make sense ??? The clutch slave ? I thought the TCI or igniter is under the battery box ?? Link to comment Share on other sites More sharing options...
GAWildKat Posted May 17, 2015 Share #7 Posted May 17, 2015 On a stock 1st gen isn't the TCI located in the left fairing? Or am I just thinking the mkII? I know the one on Mike's bike (an 87) sits on top of the air filter. But it was relocated by the previous owner. Link to comment Share on other sites More sharing options...
Great White Posted May 17, 2015 Share #8 Posted May 17, 2015 not sure on my 83, but the 86 I stripped for parts had the 41R up behind the headlight. here's what I do when faced with a weird wet miss/short situ: I wait for it to start it's miss/short behavior. Then I take a can of "wire dry" and spray a connector or wire (with engine off). I start it up and if the miss is still there, I shut it off and try another connector/wire and work progressively along the harness/circuit until I find it. It's a little laborious, but it's often the only way to find a weird miss/short when the usual offenders aren't the problem.... Link to comment Share on other sites More sharing options...
Venturous Randy Posted May 17, 2015 Share #9 Posted May 17, 2015 On 1st gens, both MKI and MKII's, the TCI is originally located under the battery box. I originally moved mine into the left side near the radio and then moved it on to the airbox. The igniters are located behind the stator and the wires come out under the clutch slave cylinder.

Mrzrex Posted May 20, 2015 Author Share #10 Posted May 20, 2015 I started out toward home from work and didn't get a 1/2 mile and started missing real bad. Seemed hard to believe that it could ingest that much water in such a short time ?? I was wanting to take it on a little trip but afraid to now !! I drove it last year to a concert and it started raining on and drove for for miles in the rain with no problem at all. I guess that is why I am a little confused about this problem from one year to the next. It is always garage kept too :-/ Link to comment Share on other sites More sharing options...
mralex714 Posted May 22, 2015 Share #11 Posted May 22, 2015 It might not be a bad idea to pull the TCI and open it to check the capacitors. Many folks here relocate them to the top of the airbox to keep them dry. Link to comment Share on other sites More sharing options...
Mrzrex Posted May 31, 2015 Author Share #12 Posted May 31, 2015 Do all the wires need to be cut and extended ?? I love the bike but NOTHING is easy to work on !!!!!!! Link to comment Share on other sites More sharing options...
mralex714 Posted May 31, 2015 Share #13 Posted May 31, 2015 Do all the wires need to be cut and extended ?? I love the bike but NOTHING is easy to work on !!!!!!! There should be enough wire to relocate it to the top of the air box. Link to comment Share on other sites More sharing options...
