Hello, everyone! A very good subject is being received, thank you!
To recall the problem again:
The engine works well and accelerates to maximum rpm smoothly and without interruption.
The butterfly valve opens normally, as it should be
Tires are factory-sized, pumped evenly.
There is no brake to hold, no bearing to hold.
My weight is 70 kilograms, I think it's not a problem
Only the maximum speed is small.
The machine was purchased from America. If it is used on a farm, can it be limited?
I'm assemble the engine now and putting it on the frame. After all I'm going to do ECU initialize. I hope there is the problem....
Thank everyone and I am open to suggestions )
I'm still suggesting testing of the shift motor. And video of the top speed vs engine rpm vs gear setting behavior. Once it's back together, of course.
