Hi, I've done all this and it's still the same, I tested the coils and even used a fifth coil and tried it on each of 1 to 4 cylinders. I now noticed the battery that was placed, btx20hl 18.9ah (20ah), could it be the battery?

I have already replaced coil #2, the problem persists...

ok, I'll check the coils, starting with number 2, the loss of power is not exaggerated but here on the island it's all mountain roads, we either go up or down never in a straight line, so I feel the loss a little. Once again, thank you very much and as soon as I have news I will pass it on.

I've already changed the TCI (I bought it from Carmo electronics), the problem still exists, but thanks for the help. I simply don't know where to look to resolve this.

My Yamaha XVZ 1200 - 83 has a problem that I can't identify what is causing it. After warming up and running for 1 hour the tachometer drops out it missfires and power loss until it stops, if I try to start it straight away it feels as if the battery is dead, the tachometer continues to not work and it continues to lose power and I hear all the relays going off, I wait about 15 to 30 minutes and it goes back to normal. Can anyone help?? Im form Portugal, Madeira island to be more precise, finding material or parts for this bike is very difficult around here.
