This came to life one very early morning .My coffee may have been too jacked that AM.
On a site I use a lot. I stumbled upon printable timing dwell tapes. So I drew this contraption.
As you know I'm no longer doing the shim/machining thing. For my riding the machining and shim has little effect.
I've been doing more research with the secondary. So I don't really count ratio anymore.
But I thought maybe some guys would find it interesting or useful.
What would be much more useful would be to permanently etch the tick marks on the secondary.
