I own a 1980 xs400 special, and recently i'ved encountered a little problem with the clutch, once i start the bike and after warming up i attempt to put the bike in any gear and it will go into gear but the bike will jump into gear, it will be like putting the bike into gear without engaging the clutch lever. And will cut the engine. I'ved checked the clutch adjustment by the book but no matter how many times i try the adjustment it will still do the same thing, please help... Thanks. The clutches and plates with cable were recently intalled.
