@cuong-nutz you can put as data on first page if you like, no images, sorry...
news are interesting...
I tried parts from my old 250 FI '09 engine on my new '13 300 engine and we have...

1. stator, rotor, rotor sensor are identical for the two and side case from FI 250 fits perfectly on
300 engine, no clearance or other issues...
2. slipper clutch can be put with no clearance issues on 250 engine and 250 side clutch case is a right bolt on the 300 engine, clutch springs are softer on the slipper...
3. 250's water pump can be used on 300 engine if the 250's oil pump axle is used on the 300 oil pump's sprocket and of course (what is more interesting for most) 300's water pump can be used on 250's engine if 300's oil pump axle is used (even better to use the 300 sprocket too which is quite lighter)
that's it so far, will keep updating as I move on with my project...
impressive how much improved, lighter and stronger the 300's components look compared to the 250's even if on the same basis of conception and functionality...
