Final drive centre hole bung and heat ?

So I bought this half decent looking rear axle plug a while ago, I think it looks neat but I noticed today after a ride out that touching the final drive casing it was pretty hot, I could keep my hand on it but any hotter and I wouldn't have.

Do you think that blocking the hole both sides is causing more heat build up ?. I've seen bungs with slots in but then water will sit in there I think.

Any ideas how hot these FD casings get normally ?.
Thanks.

I was going to get one with holes, inffact they were machined slots that created cooling when spinning, only issue I can see is water sitting in there after washing or rain ? :?

Knackers,I've been diddled.£17.99 opening gambit to draw you in with all the fanfare,then in all the excitement it's £21.49.Half a mind to send it back,till you look at the as good as identical, minus the centre sticker price on NN's,over 90 notes :o I'll quietly attach to the bike and only slightly smirk when I look at it :mrgreen:

No,it will have to come off.I used a drop of loctite so hopefully it will come out ok,seems robust enough so not overly worried.
