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...

Gilardoni 75cc cylinder

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.

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.

    Just Another Puch E50 Dio Polini (Part 2: Intake And Exhaust Matching)

    In Part 1, I matched the Polini cylinder to the case.  In Part 2, I will show how I matched the cylinder's intake and exhaust ports with the intake manifold and exhaust header.

    Just Another Puch E50 Dio Polini (Part 1: Case Matching)

    (** NOTE: I started this project while I was in Japan and finishing it up in Hawaii. Hence the changes in scenery, geographical references, and available tools. If you were wondering **)

    The moped I brought up to Japan came with an E50 Polini set up on it.  It was the first E50 I put together since I got into the Puch game over 15 years ago.  It ran pretty well with the basic match porting, stock 3 shoe clutch, stock points, Rito crank, 15mm Bing, 28mm header pipe, Magnum gutted exhaust, and 15x40 gearing.  It was probably going around at least 45mph.  It felt very safe and reliable.  But right after arriving to Japan, I wrenched it off and imported one of my ZA50s.  What can I say, I'm a ZA50 guy through and through.

    Since I had the E50 lying around, I wanted to see if I can build this E50 to its maximum potential.  I already had the Polini kit so I decided to try my hand at building a Dio Polini set up.  I know its been done before with lots of information out there (i.e Magnum Dash).  But I feel I might be able to add something into the mix.
