Review on 45 Speed Steel Gauge for Gyros 22010 by Van Masterson

Bought these to get finer jet control on a 2002 50cc 2-stroke Yamaha Vino that was converted with a 70cc big bore kit. They are very durable, be sure to use a hand drill and lots of oil. In terms of accuracy, I think these are AWG readings. So make sure you do the appropriate calculations when re-ejecting or you'll mess up your size.
