This may be getting off topic, but what exactly does it mean to allow for more timing? Does that mean the cylinder is firing when the piston is closer to the top of the cylinder, or the top of its compression stroke?

Anyway good to see another vert making good power and keep up the good work.

Thanks and good luck with your vert as well.
