Re: New build, Racer.
I can't think of any other way of getting a accurate reading. A radar gun would be perfect! I'm sure there is a math equation that would tell me based on two points. I know some law enforcement use that method when they can't afford radar guns. They paint 2 white lines on the road, and time how long its takes to cross them(I'm guessing here). I would assume the lines are measured perfectly, and the person has a stop watch.
I will go over the chain and get back with you. I didn't try rolling the bike:/
Also, I cleaned, and returned the air filter facing down. Heading to the store for plug and filter. Will post pics after.
