320 miles and still not arrived at the red zone (8000rpm). So cool but the front brake needs improvement...
I would like to keep the drum brake: any advices or experiences ?

Some news:
I have cleaned my drum with a brake cleaner and installed news Vesrah brake shoes.
The first tests show a great improvement, with more miles the results will be better: _YWN__LUV__ANGRY_.
Success for such technologie, with cleaning and grinding the old one could be used later on.

I realize I miss lot of power for a 175cc, 55 mph is too low._rnt_
First test without air filter: no change.
I am going to look the timing, and after the carburetor...=)
Compression test needs equipment I don't have but will be necessary too._want_

I am waiting tools to set the timing (timing light and puller) , it's the setting when I opened the engine...
The manual says 5 degree offset...

I tried bigger jets without clear improvement. The timing seems to be little bit different from the original setting. I need to test different positions....

Last news:
- I adjust the timing and tested with a timing light: engine is running smoothly with less vibrations but still under 5000 rpm
- Remove the silencer, no improvement.
- Compression test by 91F is 155 psi (engine still hot).
- I am suspecting a wrong position from the disc:
