Default LT80 Boyensen power reed

Looking for a bit of help here. Rebuilding the top end of a new me to LT80. I have other posts in the 'kids quads' section.

I picked up a set of Boyensen power reeds, but I've never changed reeds before. The kit contains two reeds one with a large hole in it with a piece of reed valve extending into the center section. The other reed valve looks normal shape. Which way do I install these on the reed cage? I mean which one goes on top?

Thanks!

the one with the large opening goes on first, so it is against the metal reed cage
Then lay the solid (flapper) one on top
followed by the stock metal bit that only allows the flaps to open so far

Now the carb vacuum will pull the flap open and allow air to flow

I just installed these on my LT80 build I took some pictures, however they are not of huge help here

from left to right install the parts in that order, 2, 1, 3 if that makes sense

please ignore the camo crocs

Thanks for the reply! This is just what I was looking for! The pics in your thread are awesome. That sure looks like a big project, but getting it running is sweet!

True, on a stock motor any increase in power is minimal at best.
Modify the motor for more air flow (rpm's) and they work better.

With any engine (air pump) we are only as good as our smallest bottleneck

While not a huge HP increase, they tend to crisp'n up the throttle response (they open faster)...not that an 8yo will notice
