03 rg 95cid reinharts sert k&n ac . seem that after the bike is running for awhile when i stop for gas or a very short stop the bike does not want to start and cough's back through the ac if i crack the throttle a little it fires right up. now if the bike sits for 20 min or so it starts normal. i know its some thing simple but i just cant put my finger on it battery cables are new and tight. spark plugs are new. everything looks fine and bike runs very strong, except for a little clutch slippage at high rpm's above 4k. any thoughts
