Well I ordered 2 of those 44mm Stroke Dio AF18 CMR from DynoScoot. Never heard of him but he sells a lot on ebay. Ordering the rod and the cylinder very soon too. Let the games begin.

Stock rod stroke ratio is 1.93
Most ministroke cranks have a rod stroke ratio of 1.82
Modern high strung streetbikes are 2.0+
My build will be 2.07 with a 91mm connecting rod. Ordered today from a local shop as they had them cheaper than I could find anywhere. ProX 03.1102 Note that the big end is 1.5mm bigger(width), and will need to be resized, or the crank modified. I think the latter so I can use the wider bearing. You could also use a ProX 03.2104 which is 2mm wider on the big end and 1mm shorter @ 90mm and give a rod stroke ratio of 2.05.
Zoom.

Got the CMR.. in my hand quality wise it looks better made than the OEM Honda crank I have on hand.
It uses a 2ab style rod, which looks a little spindly. However you can get a pro-x rod kit (03.1010) for Dio and throw a nice forged Japanese made rod on there if you wished.

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.
