The oil drain plug has been leaking since the first service at 1000km. Local dealer has replaced the washer, tried a silicon tape of sorts and recently replaced both the washer and the plug with a new unit. The local tech has just returned from Italy, where he underwent factory training, and mentioned this problem. The response wasn't exactly encouraging, as all the suggestions they made have already been attempted, without success. It's all getting to be a bit of a joke now. Does anyone perhaps have a suggestion to resolve this issue?

Slacken it off a couple of turns and wrap some plumbers hemp round it in an anticlockwise direction then tighten up. This will do till your next oil service when you can have a good look.

?

It's quite simple......

Either the gasket surface of the drain plug isn't perpendicular to the threads.....

or the same problem with the sump......

Probably the sump

A fiber washer would work.

So my sump plug broke in half the other day when dropping the oil ...
i had put a copper washer on it ..and thread tape and it was still leaking
i believe now that the leak was coming from a small crack inside the actual allen key area
i have sourced an after market magnetic plug from elswhere ..as the alloy on the original
seemed pretty week really and its only got 3/4 threads on it ...
anyone in oz needing one touch base and i will put you onto them
cheers Ado

There's quite a few options on the market, as discussed in other threads on here and a very common part, and then there's those also sold by the Forum Sponsors mate. :)

Had a bit of a look around ..and couldn't see anything about the actual plug itself ....and the forum sponsors are all overseas and the postage makes the price of such a small item ridiculous ...
i didn't find that the part was that easily replaced ...or found in the right size

I gave up sourcing parts locally many years ago, so unless you can go to your dealer I'm afraid you might have to look around other bike shops mate.
Maybe try Pro-Bolt ?

Some of the husky dirt bikes use the same plug 800073011
my local mv dealer didn't have one ...but the husky dealer had a couple ...
i decided to go with another brand in the end ...hoping the alloy is better than the oem :)

My issue should be resolved. The Tech dealing with my bike did a little investigating and noticed the leak was actually coming from what he says is the gearbox cover. On removal he found the seal was broken and that oil was leaking and running down to the lowest point, which made it appear to be coming from the drain plug. Awaiting spares and then we can check. Something to check for others experiencing the same symptoms?

Thread resurrection:

Just changed the oil on my Stradale and noticed I now have an oil leak through the sump plug. First time round I used the original washer, got the leak, then replaced it with a new item, but still the leak persists.

Torqued up the bolt as per manual spec (40Nm) so not sure what I've done wrong - there was no leak prior to me changing the oil.

Worth trying some instant gasket sealant around the back of the washer (against the sump)? Or maybe two washers?

Please help! What was supposed to be a simple oil change (as with all my previous bikes) now seems to have turned into a mini nightmare.

Personally, I would clean the sump area where the plug seats, clean the plug seal area, sand both side of the washer flat and clean....then reassemble and torque to spec.

Go to the auto parts store with drain plug in hand...shop for a fiber sealing washer. Do NOT over-tighten, use a torque wrench when installing.

Metal crush washers are great and can frequently be reused...but a fiber drain plug washer will accommodate minor imperfections better.
