How would you get the most LOW down POWER!

<< < (3/3)

Arigato:
Raise the compression, gear it down.  The aforementioned reed spacers work well too.

From what I understand, and I could be wrong, the reason the shortened silencer helps bottom end is by increasing the back pressure.  At higher rpm's the extra back pressure increases turbulence and hinders flow.

Or not. :evil:

You can even make a new spacer like pic.

Make either, but make inside diameter smaller than stock. It cheap to try different diameter, but start although 2-3mm smaller.

Honda use on 500cc works bikes exhaust flange with different inside diameter depend of track.

I have my own experience of that too. I ride sometime earlier DirtTrack (1km=0,62mile track) with my then bike (Honda CR480). It has bigger hole in exhaust pipe than exhaust duct in cylinder. Of course  :x :oops: I make to exhaust duct same diameter as pipe has. Everything else work fine, but starting out gone very very difficult. I put 2mm? thick washer with original exhaust duct inside diameter between pipe and cylinder and starting out work again fine! I was very happy then.  :lol:
