Warming Up Bike before Ride

[wayne z]

Hard lean angles don't affect the oil level much at all unless you are hanging off the side of the bike. Think about it, if you are centered on the bike and there was a force pulling the oil to one side, you would feel the same force pulling your body to the side.

Try taping a bottle of water to your bars or tank and watch the level when in a hard bank while you stay centered on the bike.

I always thought riders hung off the side of the bike, kept the bike more upright in turns?? Increasing the tire contact in turns thus creating more grip, to sustain higher speeds. You'll get more lean angle sitting center of the bike.

I always thought they hanged off the side to take turns faster without dragging part of the bike.

All 3 of the last answers are correct-you lean off to keep the bike more upright and increase the speed through a corner.
My comment about oil starved is for engines in general. Many changes were made in the design and placement of a pickup for that reason. Also engines were designed with hydraulic lifters to hold and disperse oil for oil starving the top.
Pontiac engines were notorious for this.

All engines are designed with a purpose in mind & designed for that purpose. On a motorcycle engine they knew it was going to be leaning hard in turns part off it's purpose so it was designed for it. I would say that running on the side stand falls in this purpose also as Miles stated if it was a problem it would be stated in the manual. It's when you take it out of purpose design that you need to ask questions such as racing. I've been around racing most of my life & built my own engines for over 20 yrs. I can tell you when you take a bike engine & put it in a car for circle track racing for best results you need to change the oil pan along with that you move the oil pickup location. Blaxmax can jump in when it comes to drag racing a bike & if there's any problem with oil being forced to the back of the pan & the engine being oil starved. That's why on a car engine when it's being used for drag racing one of the things they do is put a oil pan on with doors in it to keep the oil from doing just that.

The most important thing that hasn't been brought up here is clearances. Proper clearances are achieved at operating temp & prier to that things are loose in a engine. So the colder a engine is the looser things are. Any load put on a engine at this point can over exaggerate this & cause abnormal wear. Now times this by every time you start your engine. This is probably one of the big reasons for the orange o-ring problem as been stated. That's why for me I will be getting some engine temp before I take off.

+1 Dorney nail on the head.
I told my last girlfriend after she started her car and took off "Don't you hear the difference in the engine?"
I use a dry sump by dailey.
