Honta PA50II / Hobbit Reeds

Raymond Rexroad /

Info just obtained from Boyesen (and also added to the Wiki):

We have a few reed options available for this reed cage. The reeds we have found are a very close match, however, not a perfect match. Depending upon the width of the reed cage, you may need to slightly sand the sides of the reeds so they will fit properly.

We have a light material dual-stage fiberglass reed set, part # 6108. The price for this reed set is $25.95 USD + shipping.

We offer a heavier material dual-stage fiberglass reed set, for a modified engine, part # 712. The price for this reed set is $25.95 USD + shipping.

We also have a single stage Carbon Tech carbon fiber reed available, part # CT110LT (low tension material) for better low to mid range, or part # CT110HT (high tension material) for top end power use. The price for either Carbon Tech reed set is $32.95 USD + shipping.

All reed sets include 2 reeds, enough for one reed cage.

Cool.

Nice find.

Also - just ordered a set of #6108 reeds.

I'll pass along my experience once I get them installed.

Re: Honta PA50II / Hobbit Reeds

when you say "All reed sets include 2 reeds, enough for one reed cage" im confused, the stock reed block only has one petal...am i missing something?

Re: Honta PA50II / Hobbit Reeds

Can't answer that - I didn't say it - Cheryl (at Boyesen) did.

Since I did not send her the reed cage, I can only assume that she thinks we use the "pyramid" style cage.

When I get my order, I'll clarify this.

Re: Honta PA50II / Hobbit Reeds

Don't the PA50I models have a single reed and the PA50II models have a double reed?

Re: Honta PA50II / Hobbit Reeds

I'm using the Boyesen Power Reeds on my Honda MB5 and it makes throttle response super snappy! The Power Reeds are two-part carbon fiber; one part to help with low revs and one to open up more at high rpms, I think. They work well.

Don’t the PA50I models have a single reed and the PA50II models have a double reed?

That is correct.

The PA50I has a single reed.

The PA50II has a single reed, but has two "vanes" (don't know the correct term). I guess you could call it a double reed.

The PA50II reed looks to be twice the size as the PA50I - essentially the size of two of the singles side-by-side. I haven't measured the PA50I and compared it against a PA50II, so this is based on recollection.

Why do you ask?

Received the reeds today. The package DOES include two sets of reeds (enough for two engines). So, a new set, plus a spare, for about $25!

Too cold and icy to try them out. They do fit without any changes, too!

Re: Honta PA50II / Hobbit Reeds

They fit with NO alterations needed?

That's fucking rad.

I'm totally ordering those...

Re: Honta PA50II / Hobbit Reeds

I just ordered some myself and the lady said that they are "dual stage reeds." Which means you only get one set and are supposed to layer them. So it comes with four reeds but is technically only enough for one Hobbit. I suppose there wouldn't be too much of a problem if you didn't layer them though. Eh?

Re: Honta PA50II / Hobbit Reeds

so you've just said yourself that they are "dual stage" but you are saying in the same sentence that you should layer four together to make a "quad stage" reed...i dont think so!

i havnt bought any but judging by what rarexo says you get four because the guys at boyesen assume that we have "pyramid" style reed blocks but we dont, so rather than needing both sets of two reeds (four) for our moped we only need one set of reeds (two) and then have one set spare

Re: Honta PA50II / Hobbit Reeds

i'm pretty sure each reed has two stacked petals. i think some reeds like this have a hole in the main petal which is covered by the second petal, which is softer. at low rpm, the outside petal opens opening the hole in the main petal, then as the rpms increase, both petals open with the second petal being used to stiffen the main petal. I think they also do it without holes in the main petal, so the second petal is just acting like a 'helper spring' on a leaf-spring truck, and stiffening the main petal without adding as much mass as a thicker petal would.

i think this picture explains it:

Re: Honta PA50II / Hobbit Reeds

this would be the 'helper spring' design.

the boysen reeds come packaged like this, so i'm pretty sure there are 2 sets of 2 reeds each. you can see the holes cut out in the center of the first petal.

Re: Honta PA50II / Hobbit Reeds

I think I get it. But does the helper spring replace the metal bracket that's behind my reeds now? Or do I keep that on? I guess I'll see when I get it, I'm a little excited though. This combined with the carb thread and a secret weapon that some of you may have seen go up on a particular site is gona make me haul some ass!

Re: Honta PA50II / Hobbit Reeds

h20?

i'm pretty sure you keep the metal bracket, thats just there to keep the reeds from bending back too far. its designed using the elastic strain limit of the stock metal reeds so they dont over-articulate and crack, so it could probably be opened up for the carbon fiber, or something, but without knowing more about the two materials i cant say. def a good idea to hang onto it

Re: Honta PA50II / Hobbit Reeds

Raymond Rexroad /

Time to add info.

I have a spare NOS reed block, and I've mounted the reeds. I am left with a spare reed set. I'll use them to upgrade my sons Hobbit.

In the package comes six items:

Two new metal brackets - to replace the Honda bracket.

Two "low speed reeds". These are reeds, each with two "vanes" or "wings" or whatever they are called.

Two "high speed reeds".

The high speed reed is placed on the reed block, then the low speed reed, then the metal bracket. There is no "helper spring".

By the way, I did make sure that the metal bracket is intended to replace the Honda bracket. I did this because the Honda bracket also serves to limit how far the reed will bend. The Boyesen bracket is just a small metal piece, and it does not limit how far the reed will bend. It seemed to me that the limiter should stay, but Boyesen says nope - don't use the Honda bracket (limiter).

I'll post a picture later, when I get the time.

Re: Honta PA50II / Hobbit Reeds

what's this secret weapon travise is talking about then?

and what blasphemy is this....another website?!

Re: Honta PA50II / Hobbit Reeds

now that the reeds cover the whole plate to a farther extent, get a grinder and port the heck out of that thing. thats awesome, thanks for the pictures.

Re: Honta PA50II / Hobbit Reeds

Anyone know what Travise is up to and which website he is talking about?

Re: Honta PA50II / Hobbit Reeds

noogle, it's H2O I'm pretty certain ; )

Re: Honta PA50II / Hobbit Reeds

So you aren't using the stock metal brace with the new reeds? And it looks like you might be able to remove the plastic metal bar on the reed block now sine it's just one big reed.

Are you going to bust it out JC? From you posts it looks like water cooled is the only thing you haven't done to your Hobbit.

Re: Honta PA50II / Hobbit Reeds

what's this other website then? H2O is sweet!

Re: Honta PA50II / Hobbit Reeds

Trav, I want to sooooo bad. But, I'm scared.

Yep. Scared of getting the water-cooled kit, and NOT having the pump, hoses, radiator, etc. ready to bolt right on, and not being able to find parts that would work with it...

Seems like for that price, EVERYTHING should be included in the kit... maybe I'm just a wuss...

For now, all my loot is going to my Pinto project.

The final thing to do with my Hobbit is this reed valve thing... I'll order them very soon I'm sure.

When you do go H20, please post pics so we can see it. I'm very anxious to see one of these kits in action.

Re: Honta PA50II / Hobbit Reeds

Yeah, keep on rocking the Pinto. That things's gonna look sick when it's done.

I'm about 50/50 right now on getting the kit or not. The main draw back is the money. Since on top of the kit you need another $60 or so for the pump, a little more for the ratiator and other bits and pieces too. A lot of which can be found at a scooter shop or eBay without too much difficulty.

After all that I might not go that much faster. I'll be able to red line all day long but it might make more sense to get the racing gears. Or be crazy and get both? We'll see... pics either way!

Re: Honta PA50II / Hobbit Reeds

graham, the reed instructions I ordered said to take the reed stop off. I had to post a thread asking about it, to figure it out, but the conclusion was no reed stop. I guess some of them might be different.
