I don't know if it's the same on the newer Monsters, but on the older models the drain plug is a little bit bigger than 10mm.

If this is the case with yours, it wouldn't be a bad idea to replace the bolt with a more common size (because you'll never find a 10.5 allen wrench).

Also, a good tip is to put the magnet on the outside and not the inside. I just talked to a guy who had the magnet on his old bolt break off and was loose inside the engine.

That means yours is worn and you need a new one, they are 10mm.
Always clean it & be thorough when loosen/fasten it.

Since this thread may come up in a search - I'll share the tip I saw - I think - in DesmoTimes's manual -
if the hex wrench fit is loose you can oil & sand the wrench to achieve a tighter fit.

The drain plug on my old monster has been in and out a good 20+ times and is still fine.  The "10.5 mm." feel is because the hex starts larger and tapers down.  If you get the wrench in all the way and maintain upward pressure you will be fine.

Even Chris Kelly says it's a "not quite 10mm hex ... it fits it, but not quite perfectly."

My 10mm Craftsman allen driver has done at least 100 oil changes, never failed.

I suppose you could grind down a 7/16" for a *perfect* fit, but IMO not worth the time.

Bought a new one once, 10mm Allen fits real good.
As said before clean & keep upward pressure and you should have no problem.
And do not over tighten.

10mm but a little loose on mine too.  Only had one oil change before I got to it so I think it's always been like that.  Just make sure you seat the allen in the drain bolt completely before you trun it.  If you don't you may open it up even more and eventually strip it.  My guess is it is sand cast which makes it both slightly tapered and not a perfect fit.

+1 on the loose fit for 10mm.  If I bought a new plug, wouldn't it also be the same loose fit as the plug I have?  Is there an option to buy a 10mm plug as opposed to the 10.5mm one?

I think so.

Especially if you have an older model that's had a lot of oil changes in its lifetime. Even if you're careful, the 10.5mm bolt opening begins to get bent out of shape after a few years.

People...

Ducati makes one plug.

It takes a 10 mm allen wrench.

It is kind of tapered.

If you seat the wrench to the bottom it is not an issue.

I suppose if it just bugs you too much to have a tapered 10.5 mm allen key drain plug you could always trade it for something like this:

I truly don't give a shit but will comment so that this thread doesn't die for the following reasons:

1.) it seems to be annoying DP, and
2.) ITS A make the beast with two backsING 10 MM ALLEN

and to the above comment -- I'm not sure who the everyone your agreeing with is but its 10mm and you don't need to waste your money

I have one similar to that, mine attaches to our garden hose.

I simply drain the oil into the hose, detach the hose, and then turn on the water to clean the oil out of the hose.

It's a self-cleaning genius idea.

And whenever I need to put water into the engine, I've already got the hook-up!

Let's all Rube Goldberg it.

Want the easy solution if you have trouble with the stupid thing? Remove it, cut off a piece of 10MM allen, weld it in place to the plug, then for the rest of your days, use a socket to grab the allen.

So if you can't weld...(personally I'd braze this one as the plug is brass).

The hex head plugs aren't a bad alternative...no?

This has been an entertaining thread.  I do notice that my 10mm does not snug tight in the bolt as I would like most of my tools to fit hardware.  I'll probably try the sand/oil trick next time, but the bolt didn't strip or anything.  I am enjoying this conversation, though. [clap] [popcorn]

Everyone agrees that the OEM drain plug is a little bigger than 10mm, but a 10mm tool is what you always use.

And only a few people ever run into the "Oh crap, my drain plug is so warn that the 10mm hex won't work anymore."

The idea is to prevent that.

So, for us older monster guys, with a warn down, original drain plug that's seen many oil changes, it's a good idea to replace the OEM 10.x mm bolt with something else as a step of preventative maintenance.

How about a threaded tube that goes from the oil drain hole to the oil fill cap hole.  What thread pitch are they.  Maybe a used oil cooler hose from eBay with a different fitting.  Then instead of ever having to drain the oil, it would just be re-filled automatically.

Or maybe a hook-up to your extra nipple, you know... the one that scrapes on the ground.  Perhaps you could route it to the breather valve or the airbox.  Then the used oil could be filtered back through the top of the engine to keep your throttle bodies lubed.

So, a few pages back, Dietrich posted about an alternative drain plug.

I'd like to buy that, but there's no way to buy from that guy's website.

Not to mention, that guy's site is so ugly, it made me nauseous just browsing for a few moments.

That website is so ugly, it must have fallen out of the ugly tree and hit every branch!
