reed spacers before or after reed

[trickedcarbine]

Well, i know that the actual gains for reed spacers are so minimal that it makes buying them useless. However I am in dire need of space even with a FAST manifold. If they gotta go on will they work better after the reed or before the reed against the jug?

I have mine between the jugs and the reeds. from what I understand this will add a little volume to the cases and give you a little more kick just off idle. It in effect also lowers you bottom end compression ratio and SHOULD hurt your top end. I don't see it but then again I don't see much gain on the bottom end either. Putting them between the carb boots and the reeds should add a little velocity to the air/fuel coming out of the carb and help things up top. I think one day the reed spacer will go the way of the boost bottle.

Only reason i use them is so that my 35's clear the clutch actuator arm.

 

If they cleared without them. They would be sold to the kids down the way.

Between the Jug and reeds. The reed spacers are larger opening than the reed's so when you have them between the reeds and intake you have square shap edges haning out in the air stream. That harms flow. You want the air to flow from small to large. Not small to large, back to small. It is like having your exhaust opening being larger than the exhaust header or pipe.

normally, i would say between the reeds and carbs, because they have been known to cause a bit of breakup in the topend, and a little overrev loss. however, with vf3's, they must only be installed on the cylinder side of the reeds when you need them. installed the other way will make the cage come loose aand damage the cage...not sure if they would be useable after that. they will give you like .2-.4hp in the mid only on a ported bike. best deal with vf-3's is to get intakes that make the carb clear

Savage,

 

I think this may need to be determined by the reed being used and the inside size of the spacer. I run V2s and need a spacer fro my 35s also. If I put my spacer after the reed cage it will not capture the reed cage inside the frame on the V2s. the V3s are different dimensionally and work fine with my spacers but not with my V2s. The intake manifold captures them in place just fine and the spacers go in front of the reed.

 

I am just saying, if you run a 2 piece reed watch for this. A 2 stroke runs like shit without the reed doing its job!

 

I checked in front of and behind the reed on a previous motor on a dyno and had no noticeable difference over several pulls.

This might help. I am actually in the process of adding them to my quad (got for free) and wanted to know the same answer. I plan to try them on both sides and run against my friend's 525 Outlaw on pavement (running start bogged down in 2nd for 2 city size block distance) to see if there is any difference in the low end pull, mid and then high end (averaged over multiple runs). We did this when comparing a Dynoport 2into1 pipe against a DMC low-mid pipe to see which one pulled stronger on the bottom (I ride woods). Bought my quad for $1500 and the guy gave me both pipes for free and I'm too cheap to pay $$$ for something that really doesn't effect the fun factor I have when riding. By the way on pavement the Dynoports let me keep up with his Outlaw (only about 1 quad back) while the DMC's dropped me back about 3-4 quad lengths by the time we ran the 2 city block distance. On dirt and on the trail it was impossible to notice any differences (stock pipes were very noticeably weak on the bottom and mid and I did have trouble keeping in the pipe). I am using this 1 quad distance with the same exact setup on both my and his quad to see if the spacers do anything. Should have everything back together in about a week and see what happens.

"Yamaha Banshee Reed Spacers

Part: n/a

Trinity's 1/2" or 3/4" reed spacers manipulate intake air so you can adjust how hard the engine kicks when you open the throttle. Different sizes of reed spacers give you the ability to fine tune your quad's powerband to your personal preference. Moving the reed cage further back slightly shifts power toward the bottom end, while leaving it forward and shifting the manifold back will tend to lean towards high RPM."
