Looks like the top gear range on the speedo is 15-40. Sounds right Frank, but right now it won't run without stumbling at that speed.
Battery is here but the rear tire is off. Rear brake pivot was almost frozen but it loosened up nicely with a little oil. Rear axle was clean as new and bearings looked good. Chain is good also and rear sprocket looks good.
I'll need to pull the flywheel to change the condenser and or points.
I'm sure the front brake pivot is close to frozen and when I put the front tire on I'll get a little oil on that pivot and free it up as well.
I read that it was supposed to go 43 MPH on the original specs, on 49cc and around 4 HP.
