Question F4 750 Sump Plug-allen Key Size

Please can any MVer out there tell me the correct allen key size for the sump plug on my 01 F4 750..?

The feature on our forums shows a #10 Allen key,but that size seems too loose on my F4,and a 12 is too big...an 11 is made from unobtanium so says my local bike shop...maybe Im getting it wrong somehow..?

Is the sump plug "stepped" internally in some way...? I have 30+ years experience of servicing bikes,but I dont want to risk wrecking the sump plug then having to pay silly money to a dealer to fix it.

At 300+ for an interim service at a dealers,I thought doing it myself would save a few bob...the warranty ended many moons ago..

Any help would be great...

Many thanks

Safe rides-wherever you are MVing.....

I don't remember off hand, but I'm pretty sure it's a 10, and yes it is loose.

That's a brass plug, and it's semi likely that you'll damage it. I bought a new one in anticipation, but I haven't had to use it yet.

If you strip the head, it shouldn't be a huge deal to use a punch and hammer to get the old one out and put a new one in.

The one on my Ducati is even worse

Just a quick FYI....11mm is same as US 7/16 wrench size. If you can find American 7/16 allen key you will have an 11mm unobtanium wrench.

I am at my SPR with this very problem. Is there an answer, is it the 10mm Allen key used for the Swingarm pinch bolts?

Or do I need a 7/16?

Really close to getting her back on the road and don't need a headache right now so I am not proceeding until I know what to use.

Cheers,
Will

Thumbs up 10mm?

Eamon, Will;
its a 10mm Allen wrench
with a leather or plastic mallet give it a smart tap before trying the wrench.......
