TM KZ10C blanken tuning vs TM KZR1 SRP tuning does it need to be replaced

my engine I took it from a friend of blanken whose son was an advertising pilot and I was told that I can not buy such an engine. the cylinder was very special … But the interesting thing about my engine is that nothing is done on the clutch and I see that there are many lighter whole sets

Alternatively you could ask blanken if they can do anything more with your current 10C with regard to special parts or more recently discovered tuning

I was told when I bought it that this engine is made entirely and the clutch is original …
