Hi,
See the state of my project RG500 engine with YZ 125 1C3 top ends.
I did the cad study:

Setup engine:
- RG 400 cases
- 4 YZ 125 1C3 top ends rebored to 56mm et fully reworked + new nickasil
- 4 KTM 144 Woesner pistons
- 4 RM 125 rods 110mm fitted on news RG500 webs
- 2 specials plates to fit YZ cylinders
- water pump reworked to have an external out (better flow with water inlet on the front of the cylinders)
- stock carbs rebored to 31-32 diameter (oblong), the max we can do.
- Piaggio 125 DC rotor/stator (600g less). Same cone and pin than RG.
- new cheap racing gearbox design by me, built in italy, sold by FPE Engineering.
- special primary shaft for Z750 kawa clutch.
- and many small things....

For the moment I'm fitting the engine in my RGV frame to start the exhausts work but engine is planed to be used in a RS 250 aprilia frame with R6 08-15 swingarm (I will keep the RGV frame for my 2nd engine with RGV barrels, project stopped for the moment but 80% work done)
I will also used a self supported rear seat with the RS frame, special made by Thomas Michel from Carbon & composites applications:

It will be the same than on facebook pictures but for me it will be closed on the seat to use a seat foam (more place for upper pipes)
