Reed spacer

[frankinberg]

I just built a 153 out of a 125 I saw another thread were a guy did a double reed cage 1 as a space does any one know does that give you more low end or top end

It's not really a tuning mod as such just an attempt to compensate the increase in primary compression ratio. I wouldn't lose any sleep over it esp as it will bugger up your carb to airborne mounting distance.

From my limited experience, the reed spacer seems to soften the throttle response.

Who did the crank and how much did it cost? How does it compare to the 125? What is it not doing that you are looking to fix?
