Harley Evo's Can Make Power, Twin Cams Shouldn't Have all the Fun

Harley Evo's can make some excellent horsepower and torque with some compression and a bolt on big bore kit. You likely already have exhaust, air cleaner, jet kit and maybe even a cam. A good cam can often get your bike pushing mid 70's in horsepower and mid 80's in the torque. That puts your Evo up there with the power out put of the Twin cam 88. To get more out of the Evo reliably a mild big bore with some compression is the way to go. With a mild big bore kit you don't need to have the cases bored which is very important on the Evo due to cylinder stud spacing. The year of your motor is also important as well, not all factory Evo cases were created equal!

[@frankp7885]

What did it dyno at?

[@user-so2vs2bh2f]

I have said this before, I will say it again. All for more power, however you dont need 100 hp to keep up. For an Evo thats unrealistic without having it where its unstreetable. A good goal on hp to shoot for on an Evo is around 90 hp, and over 90 ft. Lbs of torque. How the bike is geared too makes a difference. Its fun to do quick roll on short bursts of speed, but continually running down the highway at a high speed I think takes the enjoyment out of the crusing experience.

[@everettcalhoun8197]

I enjoy puttin' at 80 mph and the motor is turning a little over 2000 rpm.

Powerful reliable and sounds better than any TC or M8. If you have a Sportie that’s different. Take it straight to Hammer and let them do it to get an actual 130 HP then shock the owner of a new stock liquid cooled Sportie and sound phenomenal compared to the new Sportie and well most anything else.

Got the 80k + miles 93' Evo Heritage OKC Show Winner in need of a topend job. I just found a good shop in OKC (quality work and tools, low rates, mega evo experience and NO attitude). I am doing most work myself. Sending shop my heads, cylinders and pistions. I like the V Twin Big bore kit with compression in the 9s with forged pistions. However, I should save $200+ by having the shop bore/hone cylinders and they will match them to new forged pistion, gauge and fit new rings and install pistions in cylinders just enough so I can install them on rods myself. I will spend the savings on clean up and worn parts in heads. The shop will set it up for a max 9:25:1 compression as recomended by Andrews for the EV13 cam. At same time, I will change lifters (overdue 40k miles). In cam chest I will change breather gear, cam bearing and install a EV 13 cam for lowend torque. It is the cam used in the "Pass a Truck" kit. I am going to have the stock CV carb professionally cleaned and rebuilt. It will be rejetted for the new CV13 cam and new 9:25:1 compression ratio. Goal is more low end torque and keep it reliable. FYI, If you have a shop bore or hone cylinders, make sure they use "torque plates". If they don't, run.

Gixxer, I don't currently own an EVO but I am not going to "knock" it either; that said I if in the future I come up on one or have a friend in need, you have just provided me with a plethora of info to pull it off! Yeah, $1200 is a little steep... keep up the good work 👍

Thank you! That's awesome to hear, the Evo's are awesome motors and very reliable. Just have to be careful when you start putting compression into them and the year of the motor.

Love the channel and the brutal honesty of the engine pluses and minuses. I see all of the issues with these big Harleys and I'm glad I went with the XL1200S Sportster way back in 2001. It came with 10:1 compression and the better heads that were on the Buell engine. Just looking at the design of the air-cooled sportster engines I wonder why Harley just did not make a bigger version for the big bikes? You made that one video about a crate engine and how much better they were than the stock engine. I would just do that unless you are a pure gear head hobbyist and want to have a project bike.

[@geraldscott4302]

The EVO is a wonderful engine. I love mine. The oem Twin Cam has some serious issues, but they can be fixed. It's not cheap, but it can be done. Which means almost another 20 years worth of Harley engines can be salvaged. Both can make more power if that is what you want. Both can be made more reliable if that is what you want. Anything that puts more stress on an engine, like making more power, automatically makes it less reliable and shortens it's lifespan. I am an auto mechanic, a hot rodder, and a drag racer. I learned a long time ago, mostly from others mistakes, that bolting on a turbocharger, supercharger, or nitrous injection will quickly destroy a stock engine. However (and this applies only to cars) it is possible to build an engine from the ground up to be a LOT stronger and able to handle a lot more stress than a stock oem assembly line engine, which can barely hold itself together at stock power levels. One reason I never tried to hot rod bikes, is that while you can get top end parts to make a lot more power, they will quickly destroy the bottom end, and there is nothing available to beef that up. That is certainly true for Japanese and European motorcycle engines. I am aware that you can get better cases, cranks, bearings, rods, transmissions, etc. for Harley engines that can handle more power. But unlike cars, I just have no interest in hot rodding a Harley. I actually ride them to relax. Very few things are more enjoyable to me than a Harley and a long open road. Just kick back and cruise. I'm actually afraid to race a bike. I'd probably flip it over. I have zero experience launching a bike off the line at full throttle. And going too fast on the street will either get you killed or cost you your license. I have a car that makes WAY more power than it did stock, but I keep that in check on public roads.

They can also be converted to a carburetor. You can get a carburetor, an intake for a carburetor, a conversion kit for the gas tank, and a stand alone ignition system. Yes, all that would be pricey, but probably still less than the cost of the cheapest new M8 model, and you get a good solid engine that still has the Harley feel and sound.

Simple problem is the design can not stand the vibration of 6000 revs. If it can't rev it can't make horsepower and with 2 valves it can't flow. But with 4 valves it can flow but can't handle the vibration. Simple if you want a vtwin that revs with power buy a ducati and leave it with your mechanic. If you want a vtwin that revs with power and reliability buy an sp1 Honda but forget economy and comfort.

Have a cammed xl1200r not sure what else besides a controller and exhaust. but it’s making close to 90-100 hp. Can tell compared to the other bikes in the fleet. Have an xs750 making around 75 hp and it’s definitely faster. it’s not a sport bike but it’s kind of fast. The other day I tried to top it out, it weaves like no ones business but I buried the speedo which tops at 120. It was all I could do to keep it in the lane and stay on it lol. Of course my Z1000 will still embarrass it, but that goes without saying. It makes as much torque at the crank (95ish, 87 at the wheel so maybe more idk) as the harely does horsepower at the wheel. and does it over an 9k rpm range, you have great power from 2500 to 11500. That said the cams really improve the character of the harely engine, let’s it rev a little more and build power instead of just hitting for a second then nothing more as you wind it up. Much more thrilling. Still if outright speeds the goal you may be better served with something else. If you’re just trying to trade smiles for miles per gallon, the cam kits in these push rod harely motors really wake them up

So from the factory it was claimed to be a 75hp/80trq and this bike doesn't run rich like the others in town with just the right smell out the pipes. And before anyone critiques the smell test I've tuned a tuned who gives a shit 500ci caddy 3 stage nitrous foxbody that went down the track with smell before airfuel meter and I got dam good and the 2 spare motors went with the car after 186 passes at the track so I'm hoping that these aftermarket cases and 12400mi mean a fun cruise for a few years.

[@GixxerFoo]

You don't see many of those bikes running around these days, you can for sure smell if a bike is running rich or smells hot. I know a lot of people will argue about that but that's something just comes from years of experience. You can't really teach that, between the smell and looking at the plugs is how it was done before dyno's.

Very informative. The only thing I would be concerned with is on the high compression motor kits is you may have to change out the starter to turn the motor over. Also If you have any knowlwdge on after market motors like RevTec, Ultima and S&S if you could do a comparisson on power, reliability and price!

[@GixxerFoo]

Compression releases are always highly recommended when you get a good compression bump. The S&S motors have been hit or miss from what I've heard, Ultima engines seem to do really well. RevTec is hit or miss, just depends who you talk to. Some people have great luck with the crate motors and others have a mess of problems. S&S really has the best warranty though.

[@iantaylor7840]

Well as I have said on many occasions, the twin cam was the best motor that HD ever made; then they fucked it by cheapening the timing case and crank bearings. The evo is a great motor also but it already runs very hot and any increase in comp or cam will just make it hotter. My buddies evo melted between the head and cylinder. As again I have also said the platform that started as 60ci and became 74ci should never have been made larger than 74ci. It simply wasn’t designed for these capacities or the poor quality of manufacture. It’s almost AMF days again, except there is no excuse this time. Plastic cam chain tensioners, badly stamped chains that cause serious wear? Come on folks at what point do you say “I’m not getting value for money”. In closing let me ask, would you have been opposed to a V4 Harley that looked the same; more finned coolant area and the same style. Capacity unknown but bigger than 74, it’s dull head thinking that has brought Harley to this point and ultimately their demise if they don’t change direction. Does anybody reading this believe that the Harley brothers and Davidson would have insisted that their bikes remain V Twins; I think not.?

[@GixxerFoo]

The Evo's for sure had issues with the rear cylinder, getting too crazy with the bore isn't a good idea on the stock cases. The big bore crate engines do very well though, they were designed from the cases up to be just that though.

[@frankmarkovcijr5459]

Stock Evo 80 cubic inch bikes run amazingly cool. Replacing the iron cylinders and iron heads of the Shovelhead brought the temperature down immensely. Now Common Sense would dictate if you're going to spend thousands and thousands of dollars to make huge amounts of horsepower and you expect the stock case to take it or the stock Driveline to be able to put it to the ground is wishful thinking at best and horribly dangerous at worst. My Evolution Sportster runs 200° 2 up in August in Florida. Because you audio doesn't get superheated from excess engine heat it doesn't lose its lubricating properties which is one of the reasons why my Sportster has 370 thousand miles on it. It seems you guys are never satisfied with any amount of horsepower. My uncle used to say of the Pinhead he rode that it rides as cool as an Iceman shoulder.

1996 and up are some of the best years of Evo engines, but even on those later models they still have lifter issues with age. With the extreme pushrod angle of the Evo they generally need a new set of lifters every 40K. That's why on the Twin Cam they moved the lifter blocks further apart to get a straighter angle.

The cases are a lot better on the late models but it is a balancing act with how close the cylinder studs are. The 88 inch bolt on is the max for dead reliability, you're not boring the cases which in turn weakens them.
