Probably the best "adjustment" you can make on that "pocket racer" is to adjust it into a scrap pile and buy a durable, safe, long-lived, high class Harley.
By now, you have found that it is a pile of rust anyway, with the "engine" concealed behind a plastic shroud. The tinny little two-stroke was designed for a chainsaw. It won't propel you over about 35 MPH, is not legal for highway travel, and is at least fifty times as dangerous as the most unstable chopper on the road.
The best way to get in the wind is through ABATE. It is a motorcyclist rights group that offers the best training ever: on the road training with the old-timers in the front so new riders can see how the professionals have been riding safely on average forty years plus.
You must first contact your local State Department of Licensing, take their classroom and closed course riding instruction, then take the written test and the drive test for your desired power classification of motorcycle.
Don't think that as a neophyte, you know how to ride. Join ABATE, let the PROFESSIONALS give you the benefit of their decades of riding expertise, and ride like we do.
How hard is that?
