Current iteration

So like I said, I got impatient and just wanted to have this thing running. I slapped it all together and here's what I came up with.
The first thing that I did is grind off all the little tabs and things that I wouldn't need. Then I cut off the seat post. I got a little too exuberant and now I'm going to have to add some matrial just below the nose of the seat. All in good time.


Once I got it running I rode it over to ADD Motorworks and had Brad reinforce the motor mounts. I've never heard of this part breaking or seperating from the frame, but I thought, "Well, it could be a potential weak point, might as well give it some more meat."


The carb and intake are a bit janky looking at the moment but I plan on putting a different carb on there anyway. Right now what you are looking at is:
-E50 port-matched to polini 64cc
-Polini 64cc kit
-Polini 4 petal reed cage intake
-Rubber hose from Matt Smith
-18mm Dellorto PHBG
-Polini Air Filter
-Motomatic N8p/N6p? pipe I don't know which model it is, I do know that it seems to sit higher on the Pinto than it did on the maxi so I can lean harder into my left hand turns.


My patented kill switch method. Send me a stem cap and a couple of bucks and I'll make you one too!


Michael Mike helped me make this extra wide pedal shaft. It's not quite wide enough though so I'm still using a bent crank arm on the left side. Its still in the development stage.

Pedaling pedaling endless pedaling...

When I first got the pinto slapped back together I had some trouble with the carburation and the electrical. My pain is your gain though, here is some video of me pedaling around trying to get it to start (notice the lack of seat... perhaps it was better that I didn't get it to fire up)

False starts, restarts, etc.

So I am going to build up a JC Penney Pinto. I've always really liked the body style and as I've learned more about moped frames I've realized that tube frames are totally where it's at. Pinto's have a great stiff feel to their ride that really snaps through turns. This is my plan in rough order:
-Tear down the frame and simplify the look of it; cut off the side panel tabs, reposition the high tension coil, rebuild the bottom end, etc.
-Strengthen the motor mount
-Install a Tillotson carb
-Install a CDI unit
-Ride and tune for a while
-Tear down again and paint/or powdercoat

Here is what the Pinto looked like when I started:



Initially I was going to paint first and build the engine off the bike. But when I got home from California it didn't take long for me to get impatient and just cannibalize most of my maxi onto the Pinto.

Thus far I have already torn down and rebuilt the whole bike and strengthened the motor mount.

I will post pictures of the Pinto's current iteration soon.
