No throttle = no oil. Would take a long and steep hill to starve the oil supply to ensure a seizure though. If the oil is already mixed in the tank, then surely it will be over oiling rather than no oil? I'm confused now. Going down a hill at 6000rpm with the throttle shut, the motor is only getting the same fuel AND oil that it would be getting at idle revs, basically. The only thing it's getting a bit more of in this situation is air.

Makes sense now, does that mean it does the same with a pump fitted also then?

According to Yamaha, of the Autolube system, the engine is always lubricated correctly in every riding scenario.

My bike is premix and i mix the oil to how i drive that particular day. Most of the long rides are with the cafe racer crowd and i would on average use 3 to 4 tanks of fuel. I then carry the oil with me in a rucksack. When Bimbling around with the cafe racers i tend to use a premix ratio of 40:1. This is due to the slow speed of the rides and if the premix ratio is lower people behind me start complaining about the smoke and the smell they have in their Jackets If i'm going out for a proper ride i tend not to go so far and usually put a 1 litre bottle of oil under the seat and make sure the tank is full before i set off. I then make sure the premix ratio is 1:28 this ratio is for really flogging the bike. Oil seems to be more and more difficult to buy once under way, thats why i always take my oil with me. To get the premix ratio correct i use an app which is on my telephone. i just select the premix ratio and type in the amount of fuel I've just tanked, the app automatically tells you how much oil to add. On the side of the bottle there are marks usually at 100ml. It is not rocket science so a little too much or a little less is not going to destroy your engine. Just make sure you leave some space in the fuel tank for the oil you have to add. Once the oil is added you have to swish the fuel around to mix it, this is easier when the tank is not brimmed. How do you manage to fit a 1 litre bottle under the seat? It is a 4LO you are talking about?? In the tail section of mine a 500ml bottle of Slime (puncture sealant) just about fits, I also have the toolkit, spark plugs and other odds and ends in there.

The oil pump subject is quite interesting. It definitely always delivers oil, but in my opinion the action is a bit delayed. Have you ever noticed the snail trail of oil on the bottom of your carbs and inlet manifold in a standard set up? I believe the oil doesn't get truly mixed until the oil trail hits the reed blocks and petals.
Personally i prefer an oil pump but with a good oil there is still a lot of lubrication in there to protect your rings and piston.

That snail trail will have a lot to with the engine coming to a stop. As it is very nearly stopped there will still be oil being pumped, but due to the low induction pressure it will be unable to reach the crankcases.

Anyone with space issues on their bike for carrying bottles of oil for premix could always consider fitting a rack and fibreglass top-box. Also handy for carrying your tea home from the chippy should advancing years have caused midriff tightness on your jacket/leathers/whatever.

Funnily enough, I’ve got a top rack for mine, will be powdercoated and test fitted to see if it’s silly enough!

Think I’ll struggle as my exhausts go up there, I’m off to see Norbo tomorrow to buy bits so will look at machined original to take pump to see what options I have, maybe see if Dean at Billet world cans modify a billet case for me

I use premix at 50:1 with Motul 800, jetting is correct for this mix I carry 3 x 100ml oil sample bottles under the duck tail, the oil sample bottles don't leak as they are designed to send, well, oil samples Each bottle is good for 5 litres of fuel, if its 4.8 litres 100ml still goes in As said above premix is not an exact science Yes I get complaints when the bike is smokey I prefer to call the blue smoke coming out the back as rust proofing for those bikes following This essentially what I do, but with a 2.5oz bottle. 2.5oz to a gallon is roughly 50:1. Best not to be messing with your oil ratio too much as this affects your jetting as well, and the diff between say 28:1 and 50:1 is actually quite alot. You may think more oil is "safer", but it really means you're getting only half as much fuel. Best practice is to pick an oil ratio and stick with it. Jet accordingly and all will be well.

I have a brand new case with the extended cover and oil pump drive, but they are £325, hence most people avoid them due to the cost
