Does anyone know if Pirate Cycles are selling their reed valve intake for Chinese 2-stroke bicycle engines as a seperate part.

I've emailed Pirate Cycles about 2 weeks ago but have not received a response.

Basically i want one, ASAP

Holy cow! I looked at pirate cycles site and indeed did find a mention of a reed kit, albeit in "pre-release" stage.

But it kind of makes me wonder - even though a dellorto carb would undoubtedly bring some performance gains, would a reed set up actually do anything noticeable on a piston port engine???
 
If it is ported for a reed setup like it will be yes.
The reed valve is gonna make a huge difference

Anyway heres what we have cooking. My engineer Ridingrich/AKA 210061741 and myself will check back often to answer questions you may have on this thread. If this pre release is up here already I do appologise. I did not post it.

PIRATE POWER SPECIAL HIGH PERFORMANCE ENGINES

Keep in mind we are currently in the testing stage and these
configurations may change.
We also would like to encourage the recommendations of the community to
bring you more of what you want. Here is the lineup.

All kits will be built from the bottom end up.
You won't find the usual metal chips and dust or need to put oil in your
crankcase.
These motors will be fully assembled with surgical precision.

We are testing high end gaskets including a full copper gasket set.

All engines will have top quality Main Bearings designed for higher rpm
and tougher loads.

The standard engine case and cover hardware will be replaced with
quality socket head cap screws. ( Put away the screwdriver get out the
allen wrench )

The clutch shaft spring will be adjusted properly. ( no more messin with
that star nut )

The small end needle bearing will be the wider PK version.

The big end bearing will be the much more reliable cage-less CROWDED
version.

All engines will be fully leak tested ensuring the highest quality.

We will offer limited warranty on the main engine components and
craftsmanship.
What exactly dose that mean ????
If you rev your engine WOT with no load till the paint starts smoking
you're out of luck.
If you mount it poorly and rip it off the bike you're out of luck.
Other than that, as usual Pirate Cycles outstanding customer service
will be provided.

We will also give you your very own Pirate T-Shirt to
sport around town wile all your friends try to keep up with you.

3X the cooling fin surface area...correct squish band, perfectly tangent, (flush), spark plug, and a concentric cylinder register make this head a real performance knocker for the PK80 engine.


Thank Jim from Creative engineering for this wonderful addition to the industry. We also have one coming for the GT5 owners.
 
Hi Pirate Cycles

I sent an email to your Yahoo address.

Can you please advise the cost of your reed valve intake system and also shipping cost to Melbourne (Australia).

I want it on my engine ASAP.

Kind regards

Fabian
 
found your email and responded.. Your from AU and my email spammed you as I figured. Sorry for that.

Thanks Fabian

Hi Justin

I've looked at the slant angle sparkplug position on the billet cylinder head and the thought crossed my mind whether it would be possible to mirror image a second sparkplug on the opposite side of the cylinder head for better combustion and redundancy purposes, as is common in aviation piston engines.

There is room in the magneto recess area for a second magneto coil to fire a secondary CDI.

I know this question may not be worthy of consideration, as your team have already done their research, but i'm curious if the possibility exists for this modification.

A lot of research went into the design of the head.
I'm sure if it was nessessary it would have been done.
Could be possible but a lot of work for an extra plug that really isn't needed.

We have a complete package here.
Built up bottom end with quality bearings and gaskets.
ported cylinder and a custom expansion chamber to match the porting.
Carb and reed intake on stage 3.

You can put a reed block on there but it will never perform like a cylinder that is designed and ported for it.
