Sorry to hear of your boil over woes..............
Did you read back through this thread and check your bike for some of the conditions that were mentioned?
One thing that jumps out at me right away is have you tried a new radiator cap or had yours tested?
The running rough part is not good. And the popping and such on trying to restart as well. What octane fuel are you running? 91 octane pump gas is more than sufficient for these bikes. And use of higher octane will make them run less than optimum.
What elevation are you at?
If you have not already, you might try pulling the radiators off and cleaning them as I mentioned earlier in the thread.
And lastly, with the radiator cap off, can you see the coolant flow start when the motor warms up? If the coolant flow is present as viewed through the cap hole during cold start up you very well could have a problem with your thermostat, as in it is stuck in one position.
Hope this helps,
