I think Tony A is spot on ,Mine gets about half full in 3000 Miles,tends to drip more I think at higher revs,but pretty accurate reply from all I been told by by everyone
I just copied and pasted from the service manual . I think MXMartin just needs to get more break in miles on that new engine/rings.

Could it be there was no oil in the catch bottle when you brought the bike in for service? Did you check it before hand? Just wondering if there was a slight overfill of oil during service and the oil in the bottle was post service.

There was about 1/2 to 1cm of oil in the bottle prior to service. I just spoke to Norton and they said exactly what you said, not enough oil in the bottle to worry about emptying it as part of the service and the additional cm or so that has accumulated post service is likely due to a slight overfill at the oil change.

Olivia explained that once the oil is fully drained a measured quantity of fresh oil is added and these two quantities don't always balance out so a small amount of overfill is quite possible which then presents itself in the catch bottle. This was very reassuring, it made sense to me. Olivia knows her stuff, I like talking to Olivia for peace of mind reassurance!

Olivia does know her stuff, and she’s very helpful.

If only Norton could get more ‘guys’ like her !

There are a couple of areas, I think one particularly in the frame, that doesn't drain well. Not speaking for everybody, but lets face it, most of us could care less about every last drop.

I'm 110% with pingu-nz the oil in air box fix is a band aide remedy only. There are variations on how to fix it but it all entails getting the engine/ oil tank to breathe. Sell the bike? Hell no, are you stupid, fix it.
I sometimes wonder why we take it back to norton or the dealers cause they can't fix it. If they did it would be an admission of a problem.

Olivia sounds like she's coached in giving guarded responses to frequent questions.
Just like an accountant pulling the wool over the eyes of business owners.
Apologies to any accountants on the forum.
It is a simple engine. Get rid of all the Euro 4 shite. Get rid of it yourself or get a good old school mechanic to do it for you.
I bought mine 12 months ago. It was expelling up to 200ml of oil via the air box fix over the rear wheel all the time.
1000 km ride last weekend, oil in catch bottle negligible, oil in air box nil.

A quick update.... Olivia's diagnosis was good, added another 165 mile since running in and oil level in bottle is unchanged.

Bens fine, but he converted his air box into and oil tank. Did you miss all the excitement of him sucking the oil out with a cartoon sized syringe?

My diagnosis. o_O;)Since I never get stuff right, every little bit helps. LOL
I emptied my catch bottle today and was quite surprised. I didn't cut the zip-tie holding it on as it looked fiddly to replace so I syringed out the contents. I got about 10cc of 'fluid' out the bottle in total and about 6cc of that was water, probably from when I got carried away giving bike a washdown with hosepipe and managed to soak the under seat area.... some of which must have made it's way down into bottom of airbox.

Sooooo, 800 miles and approx. 4cc (max) of oil in bottle

Nothing at all to be concerned about Mark , I get half full in 3000 Miles, u prob found u can just hook it out of the zip tie, wash out with petrol or turps & reinstall

Intead of a catch bottle, I just have clear tubing of a slightly wider diameter than the little black tube. After a slight overfill, I lost a bit and then lost no more. About 1200 miles since the change.

Good afternoon all, I took ownership of a 2015 961SE a few months ago, the bike has 500 some odd miles on it, SBN pipes, and ecu reflash but not any of the TSB modifications. What is the best way to handel this condition in the short term? I dont have that much skin in the bike and will probably sell it before too long as I cant have ALL the hobbies. I notice some oil drips accumulating on the bottom of the motor at start up after it had been sitting for a few months but upon the second fire the condition didnt persist. Does one pull the seat and check the airbox on a frequent basis as any sort of exercise? Thanks.

Hi there
Under the air-box should be a small drain pipe with a plug in the end .
If you pull the plug and see what drains out, could be a bit of water/condensation or could be oil.replace the plug .
I use to drain my air-box after every ride when i got home,

cheers
