it's not a banshee but maybe someone can help

I know this is banshee forum but I was thinking maybe someone could explane to me what the hell???? I have a 1980 suzuki GS850cc motorcycle and every spring when I change the oil in it and I will start it and and soon as I go to put it into gear it will just die like I have no clutch. so I will start it in gear with the clutch pulled back and the bike will surge forward like I have no clutch there. But when I let it start in gear and it surges forward I take off on it and than I try and shift and it wont shift up to 2nd gear but the further I ride it I will finally get it to shift up and than after about riding it for 10 minutes or so this shifts just fine . And it keeps doing this for usually about 4 to 5 days and than it never does it again until I change the oil again. I just thought I would ask to see if anyone could explane to me why it does this is my clutch on it's way out or what??? thanks for any help or input

A lot of bikes do that. I have a Kawasaki Vukcan 1500 that does the same thing. Found that if I start in neutral, let it warm up, then rev it a little with the clutch pulled in, then put in gear, not so bad-will still do it, just not as bad. Typical for it to lurch a little for next ride or so. Heavier oil will be more likely to do it. I'm guessing that it does this till fresh oil gets between the plates, which takes time.
