A manual would have told you that. BTW...it's called sumping (when the crankcase fills with oil after sitting for awhile). All the older big twins do it, and some Sportsters too, and it's an easy fix. It's the check ball and oil screen in the oil pump. There's a big screw right on top of the oil pump where you can access it. A piece of grit or something got in there and that's what causes the sumping. My Shovel quit doing the sumping thing the first time I cleaned the check ball screen. Also keep that breather hose AWAY from the rear tire, for obvious reasons. A well known exhaust trick is to double up the exhaust gaskets and use blue loctite on the single bolt. The single bolt system sucks and they like to loosen up after a bit. Once it warms up that oil pressure will drop off to nothing, which is normal because they run on volume, not pressure. Get that front end figured out and RIDE THAT SUCKER!

I run my breather hose across to the left side and point it at the chain and as I ride it lubes the chain

That's awesome guys. Don't you just love it when what looks major, turns out to be simple and cheap. Good work.

Nice, I always say that the #1 issue with Harleys is the previous owner. Lookin Good!

I use the woven evolution exhaust gaskets on my 78 shovelhead flh, you have to take your time and stretch them around the exhaust, but I have not had a exhaust leak since I put them on 10 years ago. And I also had a serious sumping problem with mine, I removed the check ball and spring in the oil pump and cleaned it out with a bore mop from my gun cleaning kit, then put old check ball back in an used a Teflon punch and brass hammer to lightly tap and seat the check ball, ( removed it with a thin magnet) put in the new check ball and spring, oil sumping problem went away. I do this every other oil change.

You guys seriously need more subs this channel easily beats any other motorcycle channel or chopper channel I've seen yet. Its like hidden gold. Your old man knows his shit and youre well on your way. Can't wait to see the bike buttoned up

I ran my breather hose up to a fitting I made in the top of the central vertical frame tube and fitted a filter to the bottom of that tube and a screw cap on the opening of the bottom of the tube that catches all the oil from the breather turning the tube into an oil catch can and you just unscrew the bottom cap to drain the oil off. It works real well and solves the messy breather problems.

nicely done video...good edits, excellent explanation and troubleshooting, quick and to the point very well done!

Really love these vids, great work! Cheers from Australia!

Hell yeah bro... everytime i see ur videos make me wanna go work on my bike

Great catching that breather tube, and saved tearing down the top end!👊. ☕👌💨

Had a '87 Softail that was just a monthly pain in the ass. Literally, it would run great for 3 weeks, then something tiny and stupid would break, wear out, or fall off! My wife said one day, that I spend more in a month, what a new bike payment would cost...... ....the following Saturday, I brought home the brand new Dyna :)

I'm going to check out your guys's suggestions about the overfilled tank. I think that is the problems solved that I've been looking for

Your calm and patience is impressive..

love the bike guys good pick up on the breather awsome

Good find! I keep my breather hose clear. 1983 FXWG.

Nice job kicking the bike young man. I've got 72 fly I kicked it one am. And it though me over handlebars. Since then I'm kinda careful when I do it. Took month for the arch of foot to heal. Have great day guys p,a I'm 2nd owner of the 72 got it when I was 25 now 55/still riding. But going to get newer as well as pan an knuckle it's only money when my bike was built I was in 2nd grade lol

Nice that you spotted it.

I love the sound of a shovel!

Excellent!! You're gonna be a leading Harley mechanic in the future!

Sumping ,!Oil pressure is always gona be highest when first start it idling ,or wfo ! Gd job

Great looking bike!

Crankcase vent being blocked = Not Good! LOL From East Coast Canada 😈

Had a shovelhead come in the shop smoking like that one, whoever's built it didn't understand oiling of a shove at all. First of all breather plug blocked thought that would be the end of it. Nope still smoking like a train compression test was 110 each cylinder. Leak down test all good, cylinders look good with bore scope? So I said maybe oil pump not drilled for newer style pump nope, then maybe after market lifter blocks clogged or partially clogged, Nope, pulled front head off and at least 1.5 quarts of oil drained out. Long story short, somebody build a stroke and did not machine the case for oil returns from top end.

Man great job guyz. That's fuckin rad!!!!

Crankcase breather. The downward motion of the pistons builds up pressure in the crankcase, and it's gotta have somewhere to go. If excess oil was building up in the crankcase, the check ball valve spring on the oil pump is probably weak. The previous owner probably siliconed everything because oil was probably seeping or squirting from every orifice.

I just found your channel and I'm glad I did. I want to be a harley mechanic as well any advice? I am currently an auto mechanic bu trade but I want to switch over to bikes.

I BET that is a PRIMO , 1"1/2 BELT . From the period of the build. Respect from East Coast Canada 😈

with all the silicon every where, I would check the return line .

Cool! Glad you tried the easy stuff first. Are those raked triple trees?

Cool bro!

Hugh Jorden is right but also the breather hose was to run into the air cleaner but if the bike wet-sump it would spit the oil into the air cleaner so everybody just cut the hose, you can buy a filter for it and run the hose so it sweeps up higher and that stops the puddle of oil on the ground when it wet sumps.

Whats that high pitch sound coming in when reving?

If you ever need any parts at all for that engine, he will have em., for any older harley. Tatro Machine you tube and website

Nice catch kid.

The guy seemed to have an obsession with blocking all gaps

Very cool new sub

Having no filter on the breather hose in a Dusty condition particle go into the oil equal clogger the system possibility a lot of slogan in the bottom of the crankcase

it has a scavenger oil pump there is a plug with spring and a little ball under it if the spring or ball is worn out it will puke oil out the breather tube the guy had blocked off probably why he blocked it off

AND YOU ARE THE FIRST THAT KICK START THE BIKE RIGHT WITH THE OTHER FOOT ON THE GROUND. YOU CAN SEE BIG GUYS KICK START THE BIKE JUMPING LIKE A LITTLE GIRLS

How do I fix it from dumping? Where do the hoses and screw go? I put a 5 speed transmission in. It came back sumping..it wasn't befor

Motor sounds TIGHT! I'm no expert but it sounds good to me

Put the one-way flow check valve into the breeder only to go out do not need to pull back the air from the outside it reduce or laminate oil leakage or should I say oil misting

Why did you take pic off tank?

Very cool

Awsome no smoke. Sounds great

Never assume that those before you were always on the ball. Particularly if someone states that all their work was done by Harley dealerships.

YOU GUYS WORRIED ABOUT GETTING YOUR HANDS DIRTY ??

2:31 Hell, that's easy.. He plugged the breather cause that's where the oil that made that big f'n mess came out of!

Breather plugged for storage purposes perhaps? One would hope lol.

Great work but I'd put the outer primary on, open drives can make you a cripple in an instant. Just saying.

Why did you remove MEDUSA?

still like the red heads.

hell yea bros

They plug the crank case vent tube, lol

Those brand new sparkling gaskets will leak. I used gaskets from the automotive world, cheaper and much better. You will route the breather hose so that it will not get oil vaper on your tire. Get it blowing on your chain. Engine sounds great though.

Bikes awesome guys!....love shovels.....Tatro be proud. Tatro Machine....check him out

If the guy didn't know that a shovelhead will puke oul out of that backpressure overflow he could have just plugged it off because he thought it was just leaking oil and thought that was what he needed to do, who knows because you sure cant ask him now why he did it.

ALL THAT SEALANT WILL CAUSE THE BOLT TO PULL THE THREADS OUT. CAUSES A HYDRAULIC EFFECT

MAYBE HE WAS A BANK ROBBER AND WANTED TO LEAVE A SMOKE SCREEN

It’s an engine, not a “ motor”…. Motors run on electricity…….carry on.

You obviously never spent hundreds of dollars on an exhaust that was not build correctly and does not fit or seal, and your only recourse is to use the gasket sealer to get the bike back on the road...

THOSE ONE BOLT FLANGES are GARBAGE, ALWAYS ISSUES. 2 BOLT is the WAY to GO. I HAVE SEEN SHOVELHEAD FLANGES MODIFIED TO TWO BOLTS. SUCH a SIMPLE ISSUE CAN CREATE SO MANY DAMN PROBLEMS

Bad valve guides
