4T owner here. Hold the tomatoes, please.
The rear body does ride on a scaffolding, some may say like a Lambretta. I'd argue it's more like the bigger version of a Velocifero frame.
On the 125/150, the
gearbox is pretty compatible with EFL. The intermediate shaft looks like a 2T at first blush, but it's a three piece assembly that is held together with a splined central shaft. Cush drive is 2T compatible. Clutch too. I loaded the gearbox with Italian/DRT goodies. Only really pain is that the 1st intermediate gear is 11T, which limits the driveshaft gear to 58T or 59T. An aftermarket intermediate center shaft with a 12T gear would be welcomed
Weird bits are the drive for the oil pump and the reversed drive for the camshaft. Modded cams are going to be a WebCam rework unless someone manufactures new ones. I bought a OEM spare to have reground with a GY6 A8 or A9 profile.
Stator looks like the early 2T Stella, but the CDI is a dead ringer for '80s Honda. It'll run with an Elite 80 module installed.
Was semi-smart and got the adjustable CDI for it, as well as a Polini 165 kit and a GPR exhaust before they went extinct.
Weakest link seems to be the bearings, just like other LMLs. I replaced everything in the case with SKF, except the intermediate shaft bearing. Got a legit Torrington for that. Known failure is the big end bearing. Its a weird size, but I found a replacement in NTN's catalog. Crank bearings are the same as the bigger Italjet Dragster/Gilera Runner.
If you guys want pics of the innards and such, I'd be glad to oblige.
