K2 engine

Can anyone advise on how much oil i should put in a GSXR 1000 K2 fitted in a single seater.

I know it's desirable to overfill when using a wet sump but by how much?

Can anyone who has experience of this engine shout up please.

Many thanks.

When I ran my K2 I filled it to the top of the sight glass rather than the marks halfway up..... You can see the level drops when the motor starts

Off the top of my head I think it's about 3 litres but I'll check the manual when I get home.

Is it a standard wet sump or has it got a shortened sump (or a Rilltech type wet sump)?
There is a special procedure for filling the Rilltech type sumps.

We use about 4 in ours from memory

Our test is to rev to 6k and hold it there, you shouldn't see the level drop in the sight glass.
Does take two people to do though

Right, Haynes manual (aka The Bible) says and I quote "Oil change 3lts, oil and filter 3.3lts and engine overhaul, dry engine new filter 3.6lts" You can overfill, the engine will just eject what it doesn't want.

Just so I get it clear, you mean you shouldn't see the top level of the oil at 6k revs drop 'into' the sight glass, or the level stays static?

The former, I don't like to see the sight glass change at all

We have a Rilltech sump so I assume it will be different with other kinds.

Here are the Rilltech instructions:
Setting oil levels for Suzuki Hayabusa and GSXR 1000/750/600cc
Step 1:
a.) Fill oil to just over F mark on sight glass.
b.) Remove spark plugs, loosen oil filter so there is a small air gap between filter and case.
c.) Turn over engine until 1/3 of a quart of oil comes past oil filter. Then tighten oil filter.

Step 2:

d.) Top up oil to F mark on sight glass.
e.) Loosen top oil cooler hose and turn over engine until oil is seen at connection
f.) Retighten cooler hose. Turn engine again till you see oil pressure. Refit spark plugs.
Step 3:
g.) Top up oil again to top of F mark on sight glass.
h.) Start engine and run until oil temperature is at a minimum of 150F.
i.) Hold throttle at 3000 RPM for at least 10 seconds (oil level will noticeably drop)
j.) Look at sight glass and keep topping oil up until there is a small air bubble at the top of sight glass.
k.) Stop engine and pour in another 1/3 of a quart of oil , then you are ready to go racing.
ACCUSUMP USERS NOTE:
If your car is fitted with an Accusump, ensure that the Accusump is FULL when setting oil level. If you have a MANUAL Accusump valve, this means turning the Accusump ON. If you have an electric Accusump valve, turn the Accusump on initially, while oil pressure is high, but turn it off before oil pressure drops below your valve’s opening pressure (usually 35psi).
Setting oil level with an Accusump empty means that you will be LOW on oil by the size of your Accusump, which will almost surely cause oil pressure problems.
