Though my interests are quite broad and varied in the world of motorcycles (both street and racing), I have definitely spent the most machine shop time with the Harley-Davidson brand, and have thorough knowledge of most of their engine models.
The number of engines I have personally built, modified, or otherwise machined, numbers in the hundreds. From EL-FL-UL-WL-WR-K-KR-XL-XR-FX-FLH-EVO...all the way to new TC88-95-96 and up Twin Cams. I have at some time had the pleasure to work on them all.
As I have stated before on this site; please feel free to contact me, and I will do my best to help steer you in the right direction.
