pitobread, Thank God you are a machinist and can polish that turd back into a nice ride..I feel sorry for the poor 'bolt on' builders that buy one and end up being bankrupt over a bad buy...  Even with doing most everything myself, I could have made a lot of scooters for the price that this one cost.  |

Gotta say, started first kick even with the trials bike jetting in the carb, and it is real crisp.
Downside is had to shave the intake down with a sander a bunch, will need a V3 version with a tad more clearance. It will still work however just need to shave the side down.
Will also need to take the heat gun to the cylinder shroud to get the carb to clear.
Gotta make a throttle cable next and get it out for a rip.

Its the reason why when you go on the Vespa boards 99 percent tell you just to buy an old beat up scooter and start with that... because you will end up rebuilding the whole thing anyway.
Any that are fresh paint or 2 tone be extremely weary unless they can provide rebuild pictures.

Scootertuning.ca, Scooterswapshop, probably some other places can get TWH.
That specific crank is a mega stroker, it is 50mm and requires case cutting. The TWH mini stroker looks like the jiangwayne crank.
The seals are if you have a "small" crank or "large" crank. The seal on the variator side on a small crank is different than the large crank. However you can get a seal kit from jiangwayne that allows you to put the large crank sets in there, but you need to replace also the variator bushing and drive face.
Most all the good stuff is large crank stuff.
There are also 11mm wide bearings available. Some cranks require them as they are 2mm wider so they need narrower bearings.

 I like having options. This is my 3rd crank option. that is the Stage6 R/T95 ATV crankshaft. It doesn't fit, but it does now.   |

I just uploaded a V2 Print, the first one took 30+ hours to print and used a ton of material. (like 1kg of material almost.)
After holding it in my hands I was able to see where I could cut corners on it. I also had the fan on and my layer adhesion was absolutely terrible. Sooo...
This one says its a 13 hour print in the slicer.
The fork isn't the original, I went with this mystery fork cause it had the new 10" brakes on it Mostly because when I test drove it last year the stock 8" brakes were, well horrifying.... I modified the steering lock lugs on it to get it to fit this older frame. But the shock has no dampening oil left in it so I really need to find a replacement...

I could make one for a RD350 but I don't have such a thing around me to measure it off. I am buddies with the trials dealer though, and the motor these came off of hasn't changed since 2001 so they are abundant. Also they are the right size for a 25ish Hp motor and it is a nice tidy package.
They also make a Keihin version as well if you wanna go that route.
The motor is done, I will do a reveal soon. Once I get this inlet printed and the new carb on it is "done" other than the front shock which I am having a time trying to locate. I had this PX fork (well I assumed it was a PX fork, as the motor that was originally on the Allstate was a PX200 Swap) But the PX shock I ordered is about 2 inches too long.

Here you go world, you want to convert your Vespa to reed valve? Have a 3d Printer? Can you buy a Dellorto Carburetor and have a GasGas trials dealer around you? Your in luck you can print off your own intake, use a GasGas Trials 250cc reed block and a PHBG! www.thingiverse.com/thing:2794765 |

Just read his reply...
Did he actually try and pass blame onto 90GTVert for not calling him to let him know his business was falling apart? Or that people here were negative that they paid for stuff and had zero contact or info or anything at all to tell them what was really going on?
Wow. Someone needs some humble pie. Perhaps step up to your own problems instead of saying others that have no idea whats going on are to blame.

would love to see how it really should be done! I'm a hack. My tools are mostly the same, big plate with a notch cut out of it, I use snap on sockets instead of big allen bolts to push the pin. Everything else looks similar, but I will show some build up pictures next time. |

Couldn't you use some sort of oil n heat resistant material in the 3d printer? That way you could just pop out parts haha. You should consider making a couple extra, I'm sure you could sell this setup to a few Honda guys out there. Awesome work btw. Probably, but I'm not taking any chances, but it would be awesome. The ABS is heat resistant and oil/gas too. But I think over time the studs would pull out of the plastic. |

LOL, I did a double take on that!
It really looks like my dogs face!
Sadly it is a postcard of a bear in a old record bowl.

It may work, but if it ruined this cylinder or crank I would be chapped.
I have a CNC to make at least the base plate out of aluminum. I just have to not be lazy.

I've owned one(well 2 different ones) for 2 years, honestly I misused the thing for the first year. Make a few things and basically designated it a "toy". Then I started using it for quickly making parts to see if they would fit. As once its going it's mostly set it and forget it, where as machining would take some thought.
For rapid prototypes where you don't give a shit about strength but want a visual confirmation things will work the way you intend, these things are epic. You can make pretty decent strength parts out of it if you make your infill high too.
Also there are guys on Scooter Maniacs group that 3d print intakes, they seem to hold up? I dunno I may give it a go.
