I recently put a new chain and 16 T counter sprocket on. While I love the low end grunt, my TC 1 light flashes all the time when throttling up through 1st, 2nd, and even 3rd gear. This is on pavement too. Anyone else experiencing this. Never did it before. I'm not spinning my tire either. I thought TC had nothing to do with engine RPM and Counter sprocket. Thought it measured wheel spin. Guess I'll have to go back to a 17T
Let's see if it has anything to do with production year of the bike.
Mine is March 2014 and it's perfect with 16T on TC1. Haven't tried it on TC2 yet. My bike also has new ECU (part number ending wih "2").
