Reed valves...what u running?

[ringdingrider]

just about done with my build. old Reed valve is kinda crappy. what do y'all seem to like or look for in Yer Reed valves. Ive been looking at the pyramid Reed valve from Duncan racing. any thoughts????

[JasonB]

I am running a set of V Force Reeds. Havent been riding yet, i am doing a 39pwk and custom pipe before i get out riding again so I wont really be able to notice what just the reeds do for me over the last set lol

[Shorty]

I Run Vforce3 and ESR. Both preform very well with no bugs whatsoever. I have a used VF3 reed cage with reeds in good shape I'd sell to ya for a decent deal. (it came outta a 99 CR250r) PM me for details.

If you can find one mossbarger reeds are really Good they are an 8-pedal reed block and flow like crazy.

[ringdingrider]

mossbarger is producing again.

I run VForce 2's but I've heard great things about the pyramid cage.

[RIDE-RED 250r]

I ran the 1Dir Racing reeds and cage in my stock engine. Had to go up 3 main jet sizes just from those reeds. Only trouble I had was that the reed petal life was a bit short. They would flake and deteriorate on the ends rather quickly. Never did get that figured out.

Currently running an ESR reedblock on my 350. Very little ride time to report on at this time, so I can't really comment on their performance good or bad. I will mention however that they are VERY similar to V-Force's design...

I dont really have any feedback on your reed set-up. I have ridden ESR pipe on Rad valves, Boyesons and V force cages, and honestly, I think that any aftermarket reed valve is about the same in performance.
I know they all have different flow rates on a bench, but many times that does not always translate to real world seat of the pants losses or gains. It is all in preference if you ask me, unless you have a full out drag engine that needs maximum breathing..Then Flow rates could be considered..That is just my opinion though.




READ THIS 3 TIMES because its the truth!!! in general riding your on and off the throttle so much there is no way to tell the difference!!! been there a hundred times,, i know its true!! thanks rob!

Just to add, that any Carbon Fiber reed set-up requires a constant check-up. I have seen to many of them delaminate and chip, and also just come straight loose from the retainers. When that happens, your crank bearings are gonna hate it. All reeds really should be checked and or replaced at least once per season and I really recomend inspecting any carbon fiber ones often.

Mosh have you ever Ran the Duncan pyramids in the Z?

and do you run a torque spacer? i have one on my 39mm keihin and it works well but seems to take away form top end. any opinions fellas?

just the torque spacer with standard reed cage is what i'm running with a 39mm carb.

next project is getting 38mm airstryker but not sure weather or not for reed spacer. better for low end grunting around but not so good with the top end is what i have noticed..

[ringdingrider]

duncans site says they recommend not using a torque spacer with the pyramid reed valve

[Swinger]

I have been wondering about torque spacers and what they offer performance wise. Assuming that it gives you more bottom end from its name but have wanted to run this on my trikes but just dont know enough about them.

[tri-Z ripper]

it does give more low end grunt but i have noticed it seems to give up some top end!

No I have not. Just Boyesons and VF3's.. Tri-Z's IMO, have all the bottom end in the world, and all a reed spacer does is "theoretically add to crank case volume". That combined with that factory boost bottle, small intake at the carb and the jug casting, it is just too much focus on bottem end. The Z has never been a real top end screamer, and honestly to build one like that and make it last without a balancer is a tall order. That is what everyone tried to acheive by running the YZ PV engine swaps. Whole different jug/intake size and lighter flywheel made for a different RPM range of power.
IMO I would ditch the spacer and lose the factory intake (boot at jug) and boost bottle. I do know when I put the Sprock intake on my Z it made a world of difference especially in the midrange and some top end still carrying decent bottom end. Obviously a larger carb will be needed, but I dont know if you really need to go with a PWK 38 or larger carb on a stock bore. I am not so sure they run much stronger with that large of a carb from what I have seen on stock bore engines. And they definately wont give you that much advantage or gains with that tiny stock rubber intake boot. You could always start by removing one thing at a time to, and see what it does. (Boost Bottle) then Spacer, or what have you.

I know this thread is old, but I'm interested in upgrading my stock reed system on my 85 Tri Z. Does anyone know where I can order the V force 3 reed valve's and cage?

I have been reading the wrench report and would like to start with the reed upgrade, also going to remove the air box and use the air filter recommended in the stage 2 part of the wrench report. I'd like to have my tri z ported in the future, anyone have any recommendations as to where I can have this done?

I'd like to hear some feedback from some of you who have ran the V force reeds compared to the Boysen power reeds.

Thanks!

If you want to go in on a set of the reeds i know where to get some at a reasonable price. Let me know.

Sorry I forgot to get back to you..Here is the info you need.


Factory reed cages are discontinued (I Think)...The Sets I sell are specifically made by V-force for the Tri-z.When you get the ones for the dirt bikes,,,The pedals are too stiff.The sets I sell run a meduim pedal stiffness.That was directly discussed with Moto Tassinari and recomended to be changed by him for optimal results in the Tri-z.
As far as I know( and I could be wrong) the (WR) cages mentioned above, only come in the v-force 2 series,,and will not have the correct pedal Stiffness.

The reed pedals for the new V-force 3 reed systems,as well as all gaskets will be available for replacement.In other words You dont have to wait to get replacement pedals or gaskets when you need them.

Chris,, The system I sell has everything you need.It will replace the metal spacer that is damaged on yours.You have to use your factory air boot and cut the ramps off the boot so it buts flush with the new V-force cage.While you are at it,,You will want to open up your boot a little to allow more air flow into the cage.Easy to do with a utility knife.

Here is the deal.The cage is from 2006 2007 KX 125.part number... V 303a
Reed pedal Part number is ...682m

IF YOU RUN ALCOHOL FOR FUEL you will want the stiffer reeds. Part number... 682h

The reeds are the same part number a Honda 250r.So if you want to call V-force and order them Give Him thos part numbers I just mentioned.I think they will run you right around 160 shipped from Him.I order a few sets at a time so He may charge a few bucks more to make up the Special set.I dunno Know for sure!

If you tell him you want the KX 125 cage set,,, you will get the wrong pedals.They have to be order v303a with 682m pedals to work good in the Tri-z
I have them listed on my website for 145 shipped

Call Vforce/moto tasanari and give him those part numbers. He also can offer you a larger stuffer plate for that system with more flow. Ask him about that cuz I dont have the part number for the larger stuffer. The smaller stuffer in that kit will give you more low-midrange torque.

[JasonB]

pretty sure I picked up my vforce3 carbon fiber reeds on ebay for like 200$ shipped for my 250r. That was cage and reeds and gasket. Get it. thats about the going rate. If your looking for a port job and new piston or some other goodies or motor build for your Z than I will suggest contacting Mr Sprock. He knows his stuff

[oscarmayer]

i run supertech valves! Oo... wrong parts. this is 2-smoker section not 4-thumper section sorry. ;)
lol just messin man, I iknow from riders that a lto fo guys do not like the carbon fiber reeds for normail dailey riding, they are too crisp and more peaky and snakky for racing but for normal riding, yea the mossbergs are the ticket from what they tell me. It's been a while since i did a 2-smoker. but these guys can help you a ton. good luck with the project sir!!!
