Here is an update. Took the windshield off and gas milage increased from
34 mpg to 49.3 mpg.. Reducing wind drag was the answer, can live with
that milage. Getting the tire air pressures adjusted has reduced wobble
to very little. Bryan has an idea for a steering damper that may eliminate
what little wobble there is now. Comfortable cruising speed is 50mph,
tops out on straights at 55, can hit 60 coming off a hill and hold it on the
straight, 50-55 is good enough for me. Wobble only occurs at 5 to 15 mph
when starting up. Learning to drive a hack is an ongoing process.
Bryan and Daniel did an amazing job in putting this rig together.

Ralph, the MPG number doesn't make sense.

Most "experts" will tell you that windshields USUALLY improve fuel economy, although not always. Having run my Laser 5i both with and without the large windshield seemed to some impact on economy, but I find it hard to believe that you'd see that kind of change (either higher or lower) due only to the inclusion or the exclusion of the windshield.

I suspect you had something else going on when you did you MPG testing.

JD, I was referring to the windshield on the sidecar. It is 20" tall and does
not streamline the sidecar. Remember that the SC is creating a drag effect
on the scoot to a certain degree and the windshield creates an additional
wind barrier.
After going to several reference sources I decided to try what some were
saying and took it off. As I said I went from 34 mpg to 49.3 after I removed it. Any thing that streamlines the tub improves the mpg.
I would not take one off the scoot as it does streamline it. Driving a sidecar is a whole different story. It does not operate like a trike but more like
having a wheel barrow beside the scoot, as one person said. When you speed up it wants to pull to the right, when you slow down it will tug you to
the left. Once you understand that you are preparred for it but at first it
will scare the crap out of you.
Hope this explanation helps.

Hmmm.... Thanks for the explanation, Ralph.

Now it leaves me with only one question: Based on the all the difficulties you describe when riding this contraption, you added the sidecar because...? LOL!

Simple!!! It is fun!!! And a challange!!!! And with 3 wheels I dont fall
off!!!(bad knees do not make propping a scoot up very easy).And I am crazy!!
Take your pick, any or all.
But for some reason I cant get Bryon to drive it or ride in the tub. In fact,
I cant get anybody to try it! (Bunch of young candya@#es!!!!!).

I thought that was Bryan warming up for the "True Grits Fun Run".
