I broke my knee riding trials and got bored. Thats about all i'm going to explain as to why. This isn't slow, it's already 82cc  But I want more. Que this picture I found on the net.   So im not the first, but probably the first around here. Those are 2 different builds, one using the minarelli base, and one using the piaggio, but who knows if they ever ran. But im a machinist, so I don't let that discourage me. So I dragged my old early AF18E small crank out of the shed and ordered the last R/T95 kit from ScooterTuning  So the first thing is the cylinder skirt does not fit exactly. You could easily take it out with a dremel but I have a mill, so I bored it.  And the bolt spacing needed to be opened out from the Minarelli 50mm spacing to the 47mm of the Honda. I also had to open up the counterbores a tad.  Now it all fit, but the kit comes with M7 TSHCS I was going to leave it m6 but I decided to tap the cases out to M7, however it could probably just be left M6. |

So I tapped and bolted it on for a test fit.  It looks like the inlet will work with some massaging. However it will be a restriction even with a big CT. Im working on that.   I can share how I am going to build a crank from scratch to make this work next I guess. |

Super COOL!Looks like you could mill a notch in the cyl adapter to wedge the reed box in..Would love to see the crank build up also!!  |

Heres where i'm at with the reed block.
this cylinder can produce 25-28HP without breaking a sweat. the inlet wont flow that in it's current state. Nor will the CT reed.
I want to adapt an RC-One reed and inlet there, but the cases will still be a restriction. I want to make an entirely new baseplate that will allow me to cut away the Honda cases and will allow maximum flow and provide a mount for the RC-One inlet.
i'm making 2 cranks, going to take a stab at making a bob weight, balancing and adding tungsten or carbide to try and balance it out. I am still waiting for the Pro-X rods to get here but they should be here soon.

Cool project! Im looking forward to you inlet solution!
Have you thought about relocating the inlet to the front of the engine somewhere beneath the exhaust?

There’s also this route. Intake window built into the spacer. Then just cap off the stock window. Or utilize it!   |

I want to do something like that, but use both, by bolting the plate on in the original valve spacing and then cutting away the original cases. Are those for a Jog engine? |

I was gonna say look into the MX 80/85/100/105 reed setups,but I guess its already done.. As to crank mods,its a trade off to narrow the rod,or face the crank wheels for a wide rod,,narrow rod may need a new bearing/cage,faced wheels wont grip the big end pin as well,,tuners decisions,,,,,  |

It seems it's for minarelli vertical. Made by F1 racing parts.  |

Well the Malossi mount means I can stuff a Banshee reed cage in there if need be. So the rod is this. Pro-X 03.1102. It is a 91mm length 17mm small end 24mm big end. Factory is 80mm length, same big/small end.  I will probably widen the crank slightly to allow for the bigger bearing, this makes the most sense to me vs grinding down the rod. I have 2 different cranks on the way, the CMR 44mm stroke  And also a Taida, 43.6mm stroke. Here is the page that lists the Pro-X rod dimensions by brand. Very useful to figure out big and small end dimensions. www.pro-x.com/prox-connecting-rod-dimensions-brand/ |
