I agree, I don't see them doing a shaft T7. Just saying, if they did, it would be the only one and it would sell. 600km... That's really cute.
So three times a day for some of my riding. What I used to do on the FZ-1 was spray the chain at lunch, then at the end of the day when it's still warm. I let it go a little longer than you do. Every 500-600 miles was fine for me.
