As a mechanic I tell motorcycle riders this . If your going to start your bike , only do it to go for a ride long enough to heat the oil to evaporate the water out of the oil . Don’t start it if for short periods or you will see the milking of the oil as I saw when you started the bike up . Dry sump systems on the old BSA , Nortons and Triumph had to be drained out of the the bottom after long periods of sitting or they would smoke badly . For them it was an indication of an oil check valve not doing it’s job . Gave a thumbs up for your explanation.

So this is not something I knew, but makes total sense. Thanks for sharing. Good to know!

Exactly what I was looking for , clear and understandable

Thanks a lot , I just pulled my softail outta storage and it had no oil in the tank, thank god I watched this before I added oil!!!👌🏻👌🏻👌🏻

Thanks for the video man! I was worried about this after having my bike in storage for a couple of years.

Thank you. Just went thru it myself and was concerned. Good video and information.

It's a dry sump motor and the oil will seap into the bottom end of the motor with long term sitting. If your not going to start it in the winter drain the oil tank and get the bike off the ground so your tires don't get flat spots. Ride safe ✌

Thanks, great help. Bike in storage for past 2 years.

Love your videos frank. They are awesome!!

Thanks for the info on the fat boy low on oil after storage. I was freaking out a little bit. My fat boys a 2012 but I've never let it set that long. When I didn't see anything on the floor I wondered where it went. Again thanks for the tip.👍

I have a 2000 model 883 Sportster that I've had since 2012. The thing used to leave oil everywhere from the day I got it. It sat for a couple of years after I had an accident in '17 that left me in hospital for a while. When I got round to putting it back on the road there's no oil in the tank. The only place it could have gone was into the engine, and after looking at the oil system plan in the manual, figured it must be the check valve which lives in behind where the oil filter screws on. Ordered a new ball & spring & measured the new one next to the old. The old spring had taken a set & was noticeably shorter than it ought to have been. That was 3 years ago and it's been perfectly fine since. The old thing's still a heavy spitter though. It shows it's displeasure at having the oil tank filled up more than half way through the safe zone by depositing copious quantities of oil into it's air filter box.

Glad I watched this vid before starting my bike I just filled the tank with new oil that would have been a disaster. I’m going to drain the tank start it up then do oil change. Thanks for the vid

thank you that was very helpful!

On the oil pump ther are 3 large straight blade screw caps two on the oil pump and one on the engine block the two on the oil pump. One is a check out the other is a valve check valve under that screw is a spring and a ball if the spring is broke or weak it will allow oil to flow out of the tank into the sump. Is happening to you you might want to check out the check valve and see if that may be the problem of the leaking back to the sump for the video. This is a great video. It happened to me and your video has helped great job.

Spot on!

We normally don't have that problem here in S.Tx. It don't get cold enough to park it any length of time.😅

I wish that I saw your video last week. I filled mine and had a geyser on start up.

Maybe this is why harley davidson manual says to check the oil when hot i think it says this on the dip stick also, apparently some people don't read the manual or they will know this

Yep. That happened to me.I added oil. It was not pretty. Blew out all over. Big nasty mess. I had known this first.

I inherited my grandfathers Sportster and am currently in the process of getting it going again. Was wondering why the oil tank was empty. Thank you.

Bid idea. Could blew the cylinders

i have a 96cubicinch twin cam engine and a flame blue fat boy! 2008 year model! a good bike rides like a train! six gears. i just checked the oil. but when warming up, the engine oil is 90 degrees. 😅

2000 fat boy, Mine started draining down 4years ago. Should I drain oil then pour back in? or start like you did? Will it damage the rings or walls running with no oil in the tank to begin with? Seems like a lot of time running before oil gets through engine. Thank you.

We all started at zero subs on this platform keep posting ! It’s all apart of the process

Hey brother I started my bike after winter storage and I started and it was pissing oil out of the crank case vent I never had any issues with the bike

Hello ! Oil drains from the Heritage TC88 oil tank almost as soon as I turn off the engine. What the hell do you think?

is this harleyisis chanel?

So that frothy color is normal?

Change that oil dude... plus you had all kinds of noise from the whole top end. Best of luck

What's the deal with all the rust in the oil tank 😂😂😂😂😂😂😂
