Am in the process of tuning my new 2008 203DCXLE/ Yamaha VZ250TLR combo. In the Yamaha Performance Bulletin (same engine, but on a Champ 210) they mention engine height as - "Mounting Height 4-7/8" Above A/V Plate" - what the heck is a A/V plate???and where are they measuring from & to?
Just curious, am getting close on the set-up on mine - @ 5500 am going 69 mph, GPS. In the bulletin they show the 210 doing 73.1 @ 5925 RPM's, so I guess it's OK to turn this engine close to 6000 by Yammie's specs.
Here's the link to the Yamaha Perf. Bulletin:

Anybody know the answer to where they are measuring this "Mounting Height" ?
