Booysens Reeds

[GreenPeace]

I bought a second hand KDX 200 '97. I would like to know if Booysen reeds are installed. What is the difference in looks between the original and Booysens?
The origanal owner of the bike is long gone, like a turkey in the corn....

What else can be done to improve bottom end? Whats that spaser thing that gets installed on the side of the power valve shaft?
I have a FMF pipe on.

Cheers.... and thanx for your advice.....good or bad...as long as you give advice...

The Boysen Dual Stage reeds are two reeds on top of each other, so if you have the reed block out and lift the reeds you should see another set of reeds underneath, although the ones underneath have holes in them. The top reed could be fiber glass or carbon fiber. You can kind of see the two reeds in this picture > http://www.boyesen.com/products/motorcycle/reeds/powerreedcard.gif

CarbonTech #107LT carbon fiber reeds will enhance your bottom end for about $40, and 20 minutes of your time.

Aftermarket reeds should have the oem reedstops off, too. If you have just metal strips where the mounting screws are, chances are you have aftermarket reeds, cuz that's where those metal pieces would come from.

If you still have the large, heavy, spoonlike limiters......they are either still oem, or the 'turkey in the corn' didn't put the aftermarkets reeds on right in the first place.

Doesn't matter. If the bike is new to you, you would do yourself a big favor by replacing them anyway.

re: other things that help bottom end

A KIPS that works
Proper jetting (BIG time!)
12T CS sprocket
Correct sag/shock compression clickers (application of power)
A mototassinari deltaforceII reed cage.
Use a good premix oil.
Torque ring (increase headpipe length)
Reedblock spacer
-35 FmF pipe
RB carb

Spacer thing? What's that? You're talking about a hemholtz resonator cover spacer? That's on the LH side. I don't think that's what you're talking about, cuz that is the opposite side from the KIPS activation shaft.

In any case, a hemholtz cover spacer will change the power band 'location'...when it happens. It's application/use is of some disagreement.

Oh..take your suspension apart and grease it. Steering stem, too.

Thanks for the reply. It was good reply.
Canyncarvr, you were right about the hemholtz resonator cover spacer. Thats what I was refering to. Can you please inform me more on the Torque ring and Reedblock spacer.

Thanks

I removed the reeds and from the replys I got it is Booysens reeds installed in the bike.

Thanks

just cause you got boysen reeds, does not mean they dont need replaced. Make sure they are not frayed or split on the ends and that they fully seat to the reed block.

 

[canyncarvr]

Paying attention is good. So...heed what matt sez. I'd go a step further and replace 'em anyway. The original query regarded 'bottom end'. Starting with what you know is a good, too. You KNOW reeds should be replaced best-case on an annual basis, that yours have a questionable lineage.....so get new ones!

A torque ring is cheap. I think fredette has 'em.

I think moose makes the reedblock spacer.

I've used neither of them.....don't have an opinion one way or the other. I've read a positive post or two about them....not a whole lot.

Give them a try and let everyone know how ecstatic (or not) you are with the effect!

Don't overlook the rest of the list. A 12T sprocket is a cheap + for bottom end, too!

Thanks canyncarvr

Since I live in South-Africa there are a lot of H2O between me and fredette and moose. And to ad petrol to the fire, the exchange rate between the Rand Dollar is 1-10. Thats one of the advantages living in ganster paradise.
But i will shop around here for those. Maybe i'm lucky.

Ill look into the rest of your list.
Thanks

Which Boyesen Carbon Tech Reeds does one recommend for KDX 200? The high or low tention version?

 

[canyncarvr]

re: which reeds?

Same as which jets......those that suit.

Higher tension reeds work better at higher rpm ranges.
Lower tension reeds work (you guessed'er chester) better at lower rpm ranges.

Take your pick.

 

[mlhend1]

I run mostly in tight trails that wind through out steep mountains and hills. I think I will purchase lower tension reeds for better lower end. Right now I have Boyesen Power fiberglass reeds and can see a great difference over the stock reeds. Is there a big difference between the Boyesen fiberglass reeds and the low tension pro carbon tech reeds?

 

[canyncarvr]

I haven't compared carbon to fiberglass directly. From fiberglass to a radvalve (those are carbon), but that wouldn't be an oranges-oranges comparison.
