Oke ,....at first : sorry for my poor English , I'm from Holland ...I own a '93 EVO FLSTC , I've done a few easy modifications : Crane Hi-4 single fire ignition , Arlen Ness "big sucker" air cleaner , carb re-jetting , sportster needle , adj. puhs-rods , EV-23 cam + bearing , steel breather valve , hydr chain tensioner in prim, S&S oil pump.The reason why I've chosen for an after-market cam , was just due a lack of bottem-power , when I drove my bike with a passenger. ( I don't like too skinny women , ).I did also my home-work , and was asking around ,...my greatest fear was for a cam-upgrade what could turn out in a noisy valve gear on acount of sharp grinded cam angles.My first option was finding an early type original L-camshaft ( mine was an N-type ) , but I could not buy or order it here , so I compared the spec's of the L-type with the EV-23 , and they were almost semilair except for the lift-height which is a little more for the EV-23.That's why ......As I already mentioned , it operates very silent without clicking noises , and the carb is still easy adjustable for low rpm idling . ( I run it without the VOES ).The engine is now for 3 years in this configuration , never had any problems or what ever up till now.
My engine runs great with the Andrews EV-23 cam ,....it has enough bottem-power now,...and operates silent ( no clicking noise or what ever )Replaced the bearing for a Torrinton type .Top end-power was not important to me ,...it's a Harley ,...and I want to keep the toolbox and wallet closed .If you have racing-desires , you better can buy a Ducati or so Don't forget to replace the stock-low-budget "plastic" breather valve for a S&S (or other brend) steel type .
Only you know were you spend most of your time ridding. It's a known fact the EV-27 is one of the best drop in cams ever. It's noisier than most others because of the fast ramps on the cam lobes. It comes on a little higher than most stock cams with a lot more top end. This cam really works best with a compression boost but still runs strong without it. The EV-23 is a great cam also, just doesn't give the same performance in the same rpm range as the EV-27. I went through the same thing as you when trying to decide. The bottom line is were do you spend all your time? In the lower or higher rpm. More than likely your in the lower rpm more and you want a cam that will have enough grunt to get you in the upper end quickly. Turns out there is a cam that fits this need. Ever hear about the EV-13? It was designed for heavy Harley bikes especially the Baggers that usually have two adults, luggage, and sometimes a sidecar to haul around. This cam comes on like a race horse with gobs of low end Torque to get them rolling fast. It's top end is about 500 rpm under the EV-27, doesn't need a compression increase and because of the the exhaust lobe grind helps the motor to run cooler. That EV-27 was really geared toward light bikes that like to run in the upper end. Kind of like having a Hot Rod performance that doesn't need a lot of engine upgrades because it's on the border line with it's specs. Great for Highway ridding and passing 70+ mph. Check out the EV-13, read, ask questions from people who choose it, it's an awesome cam. The EV-13 is in the middle of those two cams.

Does anyone have a stock 80" EV-27 bolt in cam only dyno sheet they can post?
Yeah, i`ve been running an EV13 in my `97 Fatboy for four years now, stock 1340 motor with a Mikuni 42. Its the noisiest cam ever, bike sounds like a bunch of Crickets in a tin can when it gets hot, i did renew the lifters with the B type at the same time.I can`t say i`m impressed with the low end acceleration but, once she gets up to about 60mph and you twist hard, boy, does it pull. You can feel the cam kicking in and it is very noticable. I thought about going up to a 27 but can`t be bothered with swopping everything out again. Its just that dammed ticking noise that gauls me, even louder when i got the windshield on. Some say that this can be cured by fitting a slightly larger pinion to take up the slack?? For now, i`ll put up with it but, its one advantage is that you can use the stock pushrods. I like stock pushrods!!

Green run is EV-27 installed, red run is after carb tuning...no other work.
