Default High idle, surging and spitting oil- 1999 Cr250

I lost my transmission plug last week on my 1999 cr 250 but i stuck a helicoil in the stripped thread and got a new plug in no problem, started the bike up and its idling realy high. surging and was spewin a lot of oil from the exhaust, i thought it might be an air leak at the carb boot but checked and could not find anything, would this be a crankcase seal? and is this a hard job?
Cheers for any help at all

Its a good possability its your crank seals. Changing them is fairly simple. You should change both right and left seals when you do it.

...and check the crank bearings carefully while you are in there.
