Thanks for the replies.
I've been in contact with NovaRossi about the engine, and they say it's an old XT12...6-7 years old
Maybe it's a mix of parts from different engines.
All parts look very similar to the NovaMega SX12 RE-T MS

I bought car and engine at eBay, and seller's description stated a NS12S5....but it's not.
I'm still trying to communicate with seller to settle this.
He sells his car as "upgraded for racing" with 4-shoe centax (??) and engine only has 1 gallon through it...sure..
Now on eBay from seller ( Fei Long from Canada,
[email protected]...be warned): a 950R with RB C3 ....
Well ...the car is OK...
I wonder if there are still parts available for NovaMega SX12 engines???
