After riding about 100 miles in hot weather my bike tries to die at stop lights and if it does die struggles to start back up? What coyuld be causeing it/

SOURCE: Battery drained while riding

chek your connection where the alternator plugs into your engine casing & spray it with electrical contact cleaner

SOURCE: while riding all lights started to flash engine run erratic bike died of death bike will not start

Start with charging and load testing the battery. Then test the stator, to test the stator on the bottom of the right down tube is the plug that goes from the stator to the voltage regulator. With a multi meter, read the voltage from the stator, I forget the exact values but as you rev the motor the voltage should climb if it dosn't your stator is bad. If the stator is good take a reading again with the motor running at the battery cables, again I forget the exact value but you should have a steady reading at the battery, if it isn't and fluctuates it is bad.

Hey Tom, gonna try and help ya here...typical vapor lock/overheating is what your describing and i sure hear a lot of it w/harleys...are you using a very high grade synthetic oil , like castrol Syntec Actevo ? are you filling up w/ premium gasoline ?
make sure your timing is not too far advanced and don;'t let it idle too low...when you come to a stoplight stand up for a strech while letting your engine get air not blocked by your legs....all these things will help greatly......Good luck to you friend...Tim

could posibly be a problem with your stator

SOURCE: whenever i press the start, the only thing it does

Have you checked your battery voltage?
