Ok, I am sure this has been asked but unlike most I actually searched for it and couldnt find anything. Do Reed spacers actually work? And do you install them between reeds and motor or between Carb and Reed Cage? Thanks guys
 
they are "in theory" supposed to give you more topend and i beleive go between the reeds and motor. however i havent herd anyone testify that they actually work. most people only use them to move larger aftermarket carbs away from the clutch lever due to clearance issues.
 
Depends on where you place it . If you need clearance for bigger carb it will go between the reeds and rubber intake boot . That position will increase velocity in the intake ports and add some top end . Placing it between the reeds and motor will produce a low end power boost due to the extra a/f taking up that space . It won't be astronomical gains either way .
 
^ i would think placing it between the reeds and boot would decrease velocity due to the extra volume and increase in diameter before the reeds. just a though...
 
Do'nt spend the money on a spacer unless you need to move the carb. Save the money and buy something that really adds performance. The spacer is'nt thick enough to make a difference, imo. You need to move stuff more to feel a gain or loss in power.

I would really be interested if anyone can back this, and this is actually true, I am in an interesting position of having a carb that clears fine, but is not as wide as stock being that is a flatslide, I have option of either adding reed spacer or buying different boot to stretch airbox or mounting my airbox further to motor, although this might cause clearance issues with YFZ rear shock as it comes close as is.

I have been looking at a reed spacer and wondering how it will affect the fact that I am running VF3's with a pro-design VF3 specific manifold which already has built in Reed Valve Air Flow Diverter to increase air speed by reducing turbulence in the reed cage. I doubt that anyone is going to know the effect without just doing it myself but if so......please chime in.

Edit: After looking you are right in that the reed spacing companies make some claims concerning placement but still do not know effect with setup.
 
they dont add power from what i read but they move the powerband for more topend or more bottom end depending on where you place it
 
I've been told you should only use them if you need more cleaence and that they don't do any thing.Honestly if you need want it and you have the skills and tools/supplies available I would make my own.
 
do not try to run a reed spacer between vf3's and the intake, the center piece of the vf3's needs the intake against them to hold it in place, with a spacer in that position the center piece will be allowed to "float" in there and will move back upon accelleration and cause major headaches, just ask slickerthanyou

and the theory behind spacers are they do not add any power gains, but instead can move your powerband up or down the rpm range
 
i would like to see a dyno sheet of some sort without a spacer then with a spacer in the to differnt locations and see if it does do anything with the way the power comes on and off
