My Evo is 21 years old. Zero leaks. Runs like a Swiss watch. Never been opened up. The secret? Start her up and let her idle for a few minutes without revving it. Let that oil pump up the lifters and get around the engine. Then off for a blast. Great engine. The most reliable Harley ever.
No one understands how crucial warming up these bikes is! Glad to hear yours is still running like a top! Totally agree with you, these are probably the best Harley engine ever made!
Yep all 5 motors i own get the 5 minute warm up. And all 5 engines are perfect. 2 have over 250,000 miles on them and they run perfect. Take care of your engine and it will take care of you
Pull the Wrist pin , never hammer it out the rod bearing in the bottom are cage bearings they bend and kink if the rod is moved by a sharp blow with the hammer . you can make a wrist pin puller out of 4 inch long 3/4 inch pvc and a 8 inch 3/8 bolt . lot safer then a hammer .
Evo is best of both worlds! Lil bit of classic look with the reliability & power building ability of new. Im going with a 1990 Evo in my chopper build.
I put a new cone on my Shovelhead last September. I couldn't get it to run good. Bought to a shop. They got it running. A couple of my bolts came loose, and oil all over my front exhaust. Tightened all to specks, not leaking now!
i had a 1989 FXLR custom lowrider with this eng. the rocker box seals started leaking on a road trip, that was a problem and lifter block gaskets leaked once.. other than that, great bike, i loved riding this bike to sturgis back in the '90's.
Ok mate, first off you need to lap the bottom of the cylinders to get them flat. Trock Tools sold a lapping plate for this purpose, it works great, I've done probably 500 motors using it and it solves the problem, updated gaskets alone usually will come back,, just FYI too late for this build. Harley made a lot of EVOs, made them until the dies got unusable, the later FXR 2,3 4, were all horrible parts. I loved my 95 inch Sputhe motor in my 84 1/2 FXRT, totaled in 2015. I lost interest with the twin cam, but still serviced them untill 2010 when I retired from H-D. Enjoy the experience and ride to live.
I have seen the lapping plate before, I think v twin might still sell them, Ive honestly never known any shops that use one though. Im sure it would be good to have but I haven't had a problem thus far without it. Thanks
@@houseofchoppers quality shops and knowledgeable engine builders use them. Also don’t use a hammer to get the wrist pins out. Make a simple and cheap press tool. You don’t want to put that kind of shock on the rods and rod bearings.
@@bigrednick100 Karen shut up already 😒 he used a rubber mallet next the jug kept the piston from side to side movement so tapping the wrist pin out wasn't a issue
It really depends on how much time you spend cleaning all the surfaces and if you have everything you need, I would say around 3 or 4 hours but I take my sweet time on motor stuff and don't rush it. Thanks!
I have never tried but would assume not. You will have to pull the inner primary, you have to tilt the engine to pull it out of the frame. Thanks watching
No you can do it in the frame, just follow the same procedure, you'll need a shortened Allen to get to the rear rocker box bolts but besides that no problem.
Base gaskets DON'T just start leaking. If they are leaking you should be looking at the cylinder condition. The leaking is most likely caused by too much crankcase pressure.
@@houseofchoppers I'm getting some slight weeping/leak that's spraying on where the front bold connects the carb to the head and caking up on the back of the carb. Also looks a bit greasy around where the top of pushrod tubes go into the head. But I'm not sure where it's coming from exactly. Any idea as to where it could be coming from? thanks
I did what the customer wanted, I offered to re ring and hone it but this is the route he wanted to go, motor ran flawless before so he didn't want to change anything.
oil leaks are normal for harleys, why all the fuss guys who buy rockets then switch to harleys are confused because harleys leak oil, boys thats norma l go ride it
They only leak due to the oil pump. Due to the bike sitting a long time without running. There is this little thing called gravity that causes this issue. ✊🏻🤫😃. The oil drops from the upper end of the motor down to the check ball and spring. If the spring in the pump is to weak that is the issue. Oil drops gumming the bottom end. Most really old engines shovels and evos. Probably older all have this issue. A little work in the oil pump spring check ball area and it’s a none issue.

Do you wait until the choke is pushed all the way in before riding? Or start riding with it at the half way point?
@@Tobagator Yes push the choke in before riding! You should really only need it for super cold start ups. Thanks
Yup I agree I never cold ride my 95

Great vid enjoyed watching this. Would take me a lifetime to strip the engine down.
Awesome tunes maaan!!!🔥🔥🔥💪🏼
Let it get nice and warm before beating it and turn the idle up a bit, the Evo will last a LONG time.
Yes! Thats the method right there!
Would be awesome if ya made more tutorials for the evo
Soon! I should have another eco build coming up in the next few months!
You dont tighten the intake manifold then torque the head bolt after?
Did you loosen the push rods before rocker removal
Holy Evo batman where did he get that timing cover ? I need one
Now if he remembers to warm it up before he revs the piss out of it you may not have to do it again!
What brand of air cleaner cover is that?
crazy i looked up oil on plugs 1340 evo this comes up a YEAR TO THE DAY
What intake filter is on that engine?
Why would need to replace the rings if you pull the cylinder?
What causes base gasket leaks?

How long did this reseal job take you start to finish???

What airfilter is this?
Just did about 4500km trough Europe on my old fxr, nice engine for sure 😊👍greetings from Germany
Looks like a Boyle Custom Moto
Need to hire you to fix my lifters on my 90 HD Springer evolution motor ! Lifter noise and I’m not good at rebuilds was my fathers bike.
I heard some Face to Face in the background. 💪👊
Damm right!
Having a problem, my cylinder head is stuck and won't pull off with out the cylinder attached. Any ideas? Thank you
rubber mallet
Is it possible to pull a evo out of a fl frame, without removing the clutch and inner primary cover from the bike ?
I have never tried but would assume not. You will have to pull the inner primary, you have to tilt the engine to pull it out of the frame. Thanks watching
No.
How has it done after running it?
Its done good so far, owner has a few thousand on her and no leaks or anything funny!
Is it expensive to fix the base gasket weeping?
gasket cheap, labor a bunch of money
PANHEADS FUREVER💜👑
Do u need to remove the motor to change the base gasket
No you can do it in the frame, just follow the same procedure, you'll need a shortened Allen to get to the rear rocker box bolts but besides that no problem.
Man, I sure wish you were my little brother...lol
Base gaskets DON'T just start leaking. If they are leaking you should be looking at the cylinder condition. The leaking is most likely caused by too much crankcase pressure.
Few years later and it still doesn't leak... gaskets still rot out over time.

For some reason youtube won't post any of my comments.

Why would you go that far and not rering the motor.. foolishness
I did what the customer wanted, I offered to re ring and hone it but this is the route he wanted to go, motor ran flawless before so he didn't want to change anything.
Mikuni
If you weld it.. It will never leak 😂🤣😂🤣
That might be the best suggestion I have ever heard hahaha
I do that with car exhausts sometimes if theyre a pain in the ass flange thats beyond a new gasket to fix
Great video....lose the music
