a recurring problem the bike will start and run down the road great but the hotter it gets the idle goes up 3 grand ,twist throttle opposite way and it goes down strange. need help.

That is fairly common actually. Usually it means that the carbs are either dirty or the cables are not moving freely. Easiest thing to do is take off the cables and lube them and slide the cable back and forth. If you have some resistance, oil some more and see if that helps, if not , new cables as any bend in the line will only make it worse.
