1000ml or if you change oil filter as well 1100ml rarely does this happen but if you drain frame oil and oil lines and change oil filter then the total oil would be 1200ml

Not sure what country you are in but where I am Australia they would be $2500 - $3900 AUD depending the condition etc

The following is from the factory service manual. Please rate my answer.

This diagram should answer the question.

Oil filler cap is on the left crankcase cover (engine side cover). This oils both the engine and transmission. Check the oil level on the dipstick located on the upper frame in front of the fuel tank. This should be done after the engine has been run briefly (idle for 1 minute), then kill engine and check.

Can I get a “very helpful” rating on this answer?

what is the torque setting for clutch pak 2005 yz450f

5liters

The oil is measured in by level, not by volumne.
So add the same amount to each fork to raise the level 10 or 20mm.
It can help to use a heavier wt oil, check the level of what is in there, and replace to the same amount.
Write notes and change one thing at a time, so you can set it back if the chanfges are not working,The manual has a lot of good info

Remove sump plug on slightly warmed motor (Not Hot!) keep bike straight up once emptied replace sump plug and refill 1 litre of oil
would highly recommend you change the oil filter as well though ?

would like to elaborate on what sort of problem so we can help ?

Turn the idle screw anticlockwise half to one turn to set if this does not affect idle speed then you need to look further inside carbi or intake valves for other issues

The last time I came accross this issue was o3 YZ 450 it would start first kick then once operating temp died never to be started again until the next day or two
if this sounds like your YZ then most likely issue is the stator - it is very easy to replace it but you do need some special tools like t30 allen key and fly wheel puller to suit your bike
Happy to elaborate on installation if you want to tackle it yourself

Left hand side of motor toward the front at the base of the cylinder there is usually plastic (Black) oil fill plug cleverly designed to be opened and tightened with just your finger (No tools required) just a funnel
good luck - regards Jamie

165 main jet and 42 pilot jet

stage one tight in correct order three or four stages to 30nm or 20 ft-lb then undo head bolts apply lube to the threads and re tighten in correct order in 3 - 4 stages to 20nm or 14 ft-lb then you mark a corner of the head bolts and turn 90 degrees this should give you a very accurate torque setting

14 mm

No unless the noise is awefull and loud or random sometimes there sometimes not then they all pretty much do that - Assuming of course that your clutch is working fine wouldn't worry to much sounds like just normal

I believe the engine and transmission are shared, using the same oil.
You should have a sight glass on the left side, and it should be checked after a warm up, and then sit for a couple of minutes. I think it's close to a quart and a half.

with carby off the bike you can carefully drill into center of the plunger enough to get a small screw to grab into it when you turn the thread into the plunger. this is usually enough to gently twist and pull the plunger out ( use little WD40 or simular to help on the way out aswell)
The metal of the plunger is very soft so with new drill bit (small one ) it will be very easy to drill and cordless drill is best nice and slow and you want just enough hole to screw a small wood screw or simalar one ore two turns
