Hello I just found this site good thing. I trying to change my fork oil on my 1984 Yamaha XT-250. On the bottom of the tube theres a hex plug and on the side a small phillips head screw. I tryed getting the hex out thought it was a plug! but it just seems to turn and not thread out! Both fork tubes are the same, I dont want to screw any thing up as I just got the bike and dont have a shop manual yet, Can some one please advise. Thank you
