First of all I have Googled for a picture of a stock TCI. What I have seen doesn't match what I found on one of my 84 parts bikes.
Is this a TCI for an 84 ?
Does it work on any other years ?
It has the Yamaha numbers 41V-85830-00 on it.
When I Googled it it shows up as an "Obsolete control unit assembly"
Just wondering.
