#Harley evo camshaft images series
Although these engines differed significantly from the Evolution engine, which in turn was derived from the series of single camshaft, overhead valve motors that were first released in 1936, they share. This is a great all around camshaft for engines with increased compression ratio, produces solid low end performance and mind blowing mid and top end power. The Harley-Davidson Twin Cam are motorcycle engines made by Harley-Davidson from 1998 to 2017.
Increased compression is required for bottom end performance. Will respond well to increased compression and head work. Will respond well to increased compression and cylinder head work. Aggressive camshaft requires performance pushrods, lifters, high flow air cleaner, stepped exhaust and high lift/high load valve springs (See #1207).īolt in for Evo engines. "The Big Nasty" Get serious with bore size, ported cylinder heads & throttle body. Cylinder head & intake work + high flow throttle body & performance exhaust recommended. Shines in 124 + cubic inch engines with added compression. Easier to tune, better street manners & revs up higher than the 508. This kit comes with everything you need to cut and weld a set of custom pipes for your Evo powered bike and is made right here in the USA. Shines in 114 and larger engines with increased compression. do it yourself builder’s exhaust kit fits all Harley Davidson Evolution engines including all Sportster and Big Twin Models produced from 1984-Present (including Twin Cam). The 508 revs up faster than the 521 grind, sounds nastier and pulls harder out of the hole. Shines in 114 + cubic inch engines with added compression. Responds very well to increased bore and or compression Great bottom end with substantial gains above 2,800 RPM when compared to stock. Great all around camshaft, Feuling's go to for 4 1/2 stroke 114" & 117" looking for a little more than our 465 grind. Responds well to increased bore and or compressionīolt-in.
