I was curious as to whether a little bit of oil leaking is normal on inverted forks? My KTM forks have been leaking for the better part of a year and the bike is only a year old. The forks have never had any severe loads placed on them. They don't leak very much just some minor seapage, like when the fork is compressed it will leave a thin oil ring on the fork slider wherever they stopped going down. it is not enough oil to cause it to drip onto the garage floor. Is this something I should worry about and do I need to do a seal change?
