new husaberg owner here.finding this site superb and very informative.the berg in question is a 2003 fc550 .havent had it long and it has sprung an oil leak from clutch cover[above the kick start] no problem i thought untill went to drain the oil.the sump plug head is completely rounded off.still no problem i thought but i cannot budge it.going to try some heat on it tom morrow ,just wondered if anyone else has had this problem and how long i can use heat for.going to try it with the engine in otherwise it will have to come out for better access.not the best start for a newie to husaberg.
