carson reed stuffers

[eli]

anybody running them ,results ?

Curious as well.

I was thinking of buyin stuffers and reeds next month and was hoping someone would chime in.

[KIRCHNER]

risYeah me too...its like nobody has tryed em? c

It’s gonna provide the same results as cutting the front, but without the machine work...

got the stuffers and reeds in a 300l promax with a special tuner.runs strong and idles good.

There's not much if any technical data on them yet that says exactly what they do, how they do it and if there is a gain in performance. I'll wait for the testing results to be posted.

[nitro_rat]

They push the reed blocks further into the crankcase thus reducing the volume thereof or providing “stuffing.” I suppose one could drop a set into a calibrated container and measure their volume. The amount of stuffing would be far easier to quantify than the amount gained by trimming the front half say .050”!

I just ordered 2 sets for my 250 efi"s twins with reeds. I think Chris told me there 0.65 thick. And he did say that the 3.0 ones have only been out 3 weeks so he's waiting for feed back.

[Bruce2]

Me and probably a few on here don't know what performance gains of even trimming the front half is...is it more lower end , mid range or top end performance?

I’ll let Jay Smith explain a little about stuffing:

Stuffing is normally done with a special grade of epoxy to equal an intake track that for some reason has more volume than another ( such as the one cylinder that has the oiler gear cavity in it )or to boost the crank case pressure to enhance the vapor speed . With more crankcase pressure the vapor picks up speed and creates a faster transition from reed to piston . Once the motor is equal in its volume from bore to bore one can take material off the front half to equally boost the compression and speed on all intake tracks. Care must be taken not to cut to much off as the reed will contact the rod bolt as the rod cycles and moves to BDC. All 2 cycles will see a performance enhancment with this mod done as long as one relizes that the weak link in the equation is the reed itself . The reed can only stand so much pressure and if over loaded with too much crank case pressure it will prematurely fail. With the reed failed the intake charge that carrys antidetonation propertys and lubrication is now allowed to back up into the air induction portion of the motor not getting to its intended destination the piston top , the motor now runs lean and will soon loose that piston !

Hope that helps,

For FAR more information on this topic a simple seach of this site will turn up volumes of information...

It also moves reeds farther away from injectors/carbs, which gives better atomization. What does a set cost?

According to Chris:

7 petal 85$,5 petal 75$,4 petal(much thicker)85$

Unless you have free access to a mill it's the best thing going...

My front is cut .050. Why are 4 petal thicker? I’ve never measured, but it seems the 4 petal cage is closer to crank already.
