Is the choke on or off? If the choke is on it will idle high one it's a little bit warm.
What maintenance have you done? Air leaks? Throttle cables too tight? -

ONe of the things in Cliff's website.
I would guess air leaks, but I'm sure there's more to it than that.Comment

I take it you mean ignition and valve train ?Comment

Probably not ignition, those usually either work or they don't.
Valves certainly need to be checked if they haven't been, but they won't cause it to rev up like that. Usually it runs fine until the valves burn.
Really there are no successful short cuts, if you want the bike to work well, do the required maintenance. Is there any record of the previous owner maintaining anything?Comment
