OK so as i said in my welcome post im trying to chase down a gremlin.. the biggest problem i have had with this bike is the electrical issues I seen somewhere to try cutting the Black/White wire to the TCI unit but when i tested all connections to TCI They all tested good. Now the question is does this mean my TCI unit is toast... I don't have the liberty to borrow a TCI unit but the local shop says if he has one he will sell it to me for 75 which is a good price since well they dont make them no more and when they did they want the same amount as I paid for this bike... I have found after market here and curious if anyone has used them http://www.regulatorrectifier.com/catalog/1984-1985-1989-Yamaha-XVZ12-Venture-1200-CDI-Ignitor. I emailed this company and was informed they come with 3 yr warranty but this is gonna be a winter project if you even call the weather in sw missouri it seems as if we go to summer to winter and back... so any imput of what i can test on the TCI box to check to see if it is good or bad?
