Fork seals on mot

Was chatting to a mate about putting an mot on my ktm 300. He said it won't pass as the seals are gone as there is some slight oil rings on the stanchions. It got me to thinking if I literally wiped them clean just before I take into the mot station how could they tell the seals were seeping slightly?
I'm new to this having a bike malarkey so please forgive my ignorance in the asking of the question!
Is changing the seals a job I could do or is it definitely a mechanics job? What' should the cost roughly be for a bike mechanic to replace them?

Thanks for your help guys

The usual thing, its an easy enough job (if you know what your doing), Im pretty sure that fork seals are an advisary note on an MOT, But if you were doing the MOT to keep it you may aswell get the seals done anyway, Ring Dene (Two Wheel Engineering) (01656 653896), hope this helps.

Maybe worth trying one of those fork seal scraper tools , on Ebay about £7 , might just be a bit of shit needs cleaning out , stopped mine seeping . Others use a bit of film negative , some on here old enough to know what that is ha ha

I would also agree with Mufynman, for the sake of a few quid try a scraper tool, I think its called ''fork/Seal Doctor'' ?), at least you wont have to remove the forks then,,,, Rob, What's a film negative ?

Are any special tools needed for changing seals on ktm standard front forks?

If its very light and depending on the tester he,l give an advisory saying fork seals slight misting.
If there pissing out its a fail as the oil will run down the leg and could contaminate the disc.
I bought a bike once with a new mot and the seals popped on the first ride.
When I took the dust seal out the twat had rolled up bog roll around the leg under seal!

I know thats naughty Steve, but it is funny, I had a mini when I was 17, it went in for MOT welding & when I got it back I thought i'd take a look, It had a fooking Frey Bentos pie tin welded in the hole, the necky fuckers hadnt even washed it out, I wondered why my little car smelt of cooked meat !!

Cooked meat , must have been an old banger :16:
My first car came from an old couple , probably why it always whiffed of piss and biscuits

Oojufink, slip a feeler gauge under the seal and move it around the fork leg with the blade at an angle.

+1 or cut out the shape of one of those fork seal scrapers out of a fizzy drink bottle. Works a treat
