I'm going to drain mine tonight and measure the amount I get out. I typically will run the bike easily around the yard a couple minutes to warm it up and then drain.

I have some extra filters as well so I may do a full oil/filter change and try to measure the exact amount I get out of it before adding. I'm curious now.... LOL

The manual explicitly states to have it between the low and high line on the sight glass. It would freak me the hell out if I couldn't see oil in that thing, but apparently people add the 1000cc and go with it...I'll go by the sight glass for piece of mind I guess. Have since the 90's when I was in elementary school lmao

Overfilling it - worst that happens is it’ll blow it out through the breather. Under fill it and it has less oil to keep everything cool and carry the clutch material in.

I’ll err on the side of over full.

At least get a slip on for your ears sake. I couldn’t deal with the obnoxious stock one for more than a few rides. The pro circuit slip on makes it a much more pleasant experience.

I added the 1000cc started it up and it wasn't in the sight glass. So I added another 250 and let it run and came back and the oil was in the middle. Weird! I didn't pre-fill my oil filter last time though do you pre-fill it with oil?

So you added 1250 CCs?! It's not a fn V-twin.

Adding 50-100cc to reduce clutch whine or whatever is one thing. Overfilling the manual spec by 40% is ridiculous.

Step away from the bike please.

Way more bad things can happen then just having some blow out of the breather... Esp when talking about an extra 300ml of oil. Excessive crankcase pressure is terrible for the engine.

I have burned up two pair of pants and starting to get a pair of boots doing 4-6 starts it’s burning on the expansion chamber. Don’t know if I’m just being a squid or if it’s just the exhaust sticking out so far

Dude NO, stop with the sight glass shit. Go by the manual and only the manual. It gives clear numbers for oil changes with and without the oil filter. These bikes are built for specific tolerances. You are playing with fire when you eyeball that and go by a stupid sight glass. Jesus

I've posted this quite a few times now but the manually states (and I got it right here, typing it word for word):
"Check the engine oil level with the motorcycle vertical through the oil level inspection window on the lower right side of the engine. The oil level should come up between the high and low level lines next to the inspection window".

Word for word. So yes, exactly, go by the manual.

I've also done this on pretty much every single bike I've ever had since 1992. I agree, measure first, then go by the sight glass. If it's between low and high after adding the measured oil your gold. I also mentioned I only eyed the cc level and I probably only added between 100-200ccs of oil. It went from not being in the sight glass to being correct.

If the sight glass is 100% full you aren't going by the manual. If the sight glass is empty, you aren't going by the manual.

Manual also states you need to replace its muffler damper every 3 races! Probably need to do that soon lol

The stock one burns by boots. The FMF Powerbomb I had on my 05 RMZ450 burned them in the same spot. I'm short and wear the Oneal RDX and the boots have a very tall inner protection guard/pad that saves my pants. You can see in my profile pic exactly how/where it happens.

Well I'm sittin here going through it and the flippin' manual doesn't cover that! I never purchased an aftermarket cover do they state that the oil levels change?

Ha my other bike doesn't have a glass I do 1300 (manual states 1250) on a 05 rmz450. Never had an issue.

I thought I was making an interesting comment as to why I thought my oil level wasn't to my expectations after the first oil change. I believe I would have been fine. The whole ordeal was I put in 1000cc and it was a the low line in the sight glass. Thought it was odd so I added another 100-200 to make it fuller in the sight glass. You're right, go by the manual and not be so OCD like myself. It's my baby and I don't want anything to go wrong because I was slightly low on oil. It's my first brand new bike so you bet I'm going to be insane. It's like a first born over here. Next time I'll measure it out exact and let it sit overnight to see where it ends up.

Is your bike on a stand when you are looking at the sight glass? If so that could cause a misreading of the level if it was tilted to far forward or back. Stand the bike up on flat ground and check again.

An extra 250 sounds like a lot and not filling the oil filter sounds like a bad idea.
