Puch No. 5

Finally got to my final bike. My FIFTH Puch out of seven total mopeds!! It's a Pinto I scored of Moped Army Buy & Sell forums while I was in Japan. I didn't have my garage back then so I wrapped it up until I returned home to Hawaii. Now its time to unwrapped it!!...








Finally It's Autisa Time


70cc Autisa Kit
After 20+ years in the Puch game, I can finally build a Puch 70cc Autisa set up to call my own. Back in the early 90s when I got into this Puch business, kits were very hard to come by in Hawaii. Either they were all gone, too expensive for a high school kid to afford, or people who had them were reluctant to give them up. Even today, the people who have them still don't want to part ways with their beloved kits. I remember it was one of two kits (the other being the 65cc Zeta kit) that I knew of. I rode several Puchs with this kit on. And I remember them as being super fast and fun.

For the sake of nostalgia, I set out to build my first Puch Autisa kitted bike...

I scored this kit on the Moped Army Buy and Sell forums. At first, I couldn't believe what I was seeing. It was used but from one of the guys from Treats. I quickly snatched it up. A week later, I found it on my door ready to be reborn. This kit was so untouchable back in the day. A well tuned Autisa setup could easily take down any two-stoke bikes that where on the road those days such as YSRs, Hondas, and Yamahas. Let's pause for a moment and take the time to admire this old school cylinder's craftsmanship:

Front
Exhaust
Back upside down

Back right side up
Piston intake side
Piston top

Piston upskirt

Piston exhuast side

70cc high comp head

Port matching:

I did some light port matching on this one. Didn't want to go all out like my MetraKit build. All I did was match the chambers and cleaned out the manufacture imperfections. Left the port timing stock. Saving these mods for later. Just eager to the this on the road!!

Cha...
Cha..

Chambers!!

Chambers!!
Chambers!!





Prep for 20 tooth front sprocket:

Nothing new. JB welded the magneto side just in case. Ground the sprocket side. You don't have to go all the way through to the magneto side for the 20t sprocket to fit. 20 tooth sprocket mounted.


Plugged the oil pump:

First, I JB welded the inner tube with the O-rings on each end. Then I did a variation of an old school 28 cents plug. If you get three pennies and a quarter, the thickness is enough to fill the gap from the inner tube to the surface. Then you would use some washers and screws to secure it in. In this case I ditched the quarter and used a brass plate instead. 3 cents!! Put some gasket sealer for good measure. Pau!! Sealed!!





 

Stock clutch modifications:

Kept it old school and did a cut and flip mod on the stock clutches. Used my trusty spring installation tool and boom!! Pau. Instant stall!!

Transmission buttoned up:



Piston installed:


Cylinder and electrical on:

Decided to go full old school with the stock points ignition system.


Carburetor on:

Using a PHBG 20mm Dellorto I had lying around. Also modified a Puch Magnum X Bing 17mm manifold that I also had lying around. I tried my hand at Alumiweld to plug the manifold's bolt holes and re-drilled. That stuff really works great!! Made a sheet metal intake shim for it to mate up with the carb. I probably make another intake manifold in the future but wanna get the show on the road now!!


Mounted:

Magnum exhaust modified
K&N filter
Waiting on white walls...you heard me white walls!!
Stay tuned for the completion...

A Homage To The Old School

This is a homage to the old school. An introduction to the newbies on how to tune the old school way. Proof that you don't need big bore kits or fancy pipes to go fast. All you need is some 50cc stock parts and a whole lot of two-stroke know how.

ZA50 Big Port Metra Kit Redux

Before I left for Japan, I was in the middle of building my black Magnum. I built a ZA50 big port MetraKit for it. But in the rush of moving, I just slapped this motor together in order to mount it on the bike for storage. I never ran it. It sat at my wife's grandmother's house for the past 5 years. Now I can correct some of the mistakes I made. This is the Redux of my ZA50 Big Port MetraKit for my Magnum...

Giant!! But it wants more!!

Shelved

Here Lies My Gila ZA50...
SHELVED!!!  The Gila ZA50 set up I used to blast around Japan is currently on the shelf in way of more exciting projects for my bikes. I can't believe THIS motor is my least interesting project right now. I will eventually put it on my FIFTH bike. Probably strip it down and rebuild it first. For now, it will remain in slumber...

Specs:
Puch ZA50
Gilardoni 75cc cylinder
MetraKit head
V Force 8 petal reeds
Tecno Estoril exhaust
Mikuni TM24 Carburetor

Moped Junkyard

Pics of my cousin's place. There are tons of good parts and bikes that his brother-in-law them left. Those stuff are deteriorating fast. What a shame. They used to have some of the best bikes out in Hawaii. Hopefully they will let me buy them out in the near future so I can save what's left. Currently they are reluctant to sell. S.O.P....SAVE OUR PUCHS!!

(Some parts not shown here are: Autisa Kits, 32t rear sprockets, dellortos, etc)

Hiding in there are a couple of Puch Maxis with full chrome front ends and shocks.

Puchshop.de


I recently shot an email to the guys at Puchshop.de inquiring about the price of shipping to the United States, in particular Hawaii. To my suprise, they responded really quick. Chris, at Puchshop said they do but the cost is rather expensive. If you visited their site, you probably saw a build on the blog section of that track bike with a custom body kit. Really awesome build! So I asked if they were going to update their blog anytime soon. He said no because they prefer using facebook. But he sent me links of three bikes they built. It's on puchforums.nl site. You gonna need a login and password to view it. Get an account beacause these builds are worth seeing:

  • Build 1


  • Build 2


  • Build 3



  • So I asked what set ups are they running. He responded with:

    We are running all 50cc; mostly the Athena AJH and non reed Athena 50cc tuned to the max.

    For example:
    50cc AJH cilinder, 19mm Polini CP carb., Rito crank, PVL ignition, PSR Homoet P6 exhaust, PSR cilinder head with O-Ring, HK clutch, all tuned and matched to the max.
    Speed 72kmh with 13-48 sprockets at 14.000 rpm:-)


    50cc @ 14,000 RPM!!! Damn!!!

    Just Another Puch E50 Dio Polini (Part 4: Finishing Up)

    In Part 3, I showed my transmission mods. In Part 4, I'll be putting it all together. I won't get into the how to's of putting an E50 back together because there are tons of tutorials on this subject. Check out this one from the Moped Army Wiki site. Here's a cool one I tumbled upon.
