If it's a Harley EVO engine;
The later EVO engine identification numbers will be on the primary side case, just above the primary, and centered between the cylinders.... Internet pic

I posted where to find the engine identification numbers if it's a Harley engine, and you haven't shared any info regarding that...
Both eighteight and I have asked you to post some pics, and you haven't responded to that....
Yet you respond to the guys who hurt your feelings, by suggesting you use some punctuation so your run-on sentence post is easier to follow/understand...
Good luck with your repair, I'm out....
