I also think those crank's in the pic's will be ifmar and some outher spec. I would look into an engine befor you go to your place of purches and make shore you buy an ifmar spec engine. Providing that ifmar std and limatations are legal for your country or class of racing. Normaly and ifmar aproved engine will have an ifmar aproval in the code (eg, LL3 ifmar crank). Best Regards Jeremy.
They have not changed the spec. There are 2 distinct different engines with different part numbers. The crank on the right was made specifically for the EFRA 2006 and BRCA rules and now that EFRA changed the rules Novarossi has excess stock.
For performance all you need to do is lower the head shims on your engine and it will match the moded crank version
