All about reed spacers -

[3Razors]

I agree BDI, good info there.  My KX5 is pretty modified ie porting, head rechambered, NOS nitrous, and pvl ignition.  The idea of the reed spacer has been tooling around in my mind but never did use it because I didnt want to loose any top-end.  I've been debating between the V-Force and Rad Valve cages and by all the replies using the search sounds like the v-force is the way to go.  I have been using stock for the longest time and have been happy with them but I like to tinker for more hp but at the same time I really despise spending money on a product that doesn't perform the way I am hoping.

or you can raise the cylinder with a spacer

wont this also increase crank case volume ?

can i mill of the area where the reeds bolt on to decrease crank case volume?

BDI..I have a "top end" pipe ...it's a custom made down pipe with a removeable/serviceable silencer..It's was custom built by Gemco ( they make alot of pipe for the RD-350-400 yam. and the triple Kaws ) The previous owner had it made for Road Race/ S. Motard...I'll sell it if you are interested...also I have a custom built reinforced swing arm ( like a crotch- rocket swingarm)..I don't use ...I race MX....E-mail me if your interested............Kerry

There aren't any real good pics of a reed spacer so I took some.  Heres some pics as I cut out the spacer from a 3/8 Aluminum.

[Johnniespeed]

I was lazy and bought the Moose kit, the price of two gaskets and longer bolts was almost the same as the Moose kit.
Did you use a plasma cutter for the cuts ?  I have a plasma cutter but have never used it on aluminum. I usually just cut  aluminum with an end mill in a vertical mill.
 Looks like the end result will perform as good as any other. Good Job !

[ImmortalSoul219]

No I used all hand tools and a drill press.  Used a copping saw for the cuts and a file to clean up the cuts.  My shops a half  hour away and didnt feel like driving out there this morning so I just did it in my garage behind the house.  Took me about 2 hours or so.  The hole project cost me about a few bucks.  The aluminum was free,  longer bolts were like 10 cents each and the gasket was like a couple bucks.

HEY AWESOME COULD ONE OF THESE SPACERS BE MADE OUT OF HARD PLASTIC LIKE THE TYPE A CHAIN GUIDE IS MADE OF, GREAT TO SEE ALL THESE MODS.

[ImmortalSoul219]

Can a mod move this to the sticky on this topic by chance?  Might be a good place for these pics.

[Danger4u2]

There is a sticky on reed spacers,  that's why you should do a search before you post a question.

This thread moved.

Yeah if you really wanted too.  You can make it out of anything you want but that doesn't mean you should haha.

Installed the Moose spacer.  Bike already has a set of Boy. dual stage reeds.   Seems smoother.  Amazing how desert riding in the tight stuff how fast you can go on 1/4 throttle or less most of the time.   My buddy swears by the RAD valve and V-force.  Has one of each in his bike and his brothers.   Told him the RAD is " right in Dumpster".   Stock would be better and more reliable.   Says no way, gained more power with it.     None of them can still beat my 02 KX500 that has only a pipe, stock gearing and the reeds.   Like the excuses they come up with.   How me being 150 pounds is not fair.   Going to work on my suspension next.  Bike has more than enough power for me as it is.
