Sounds stupid but is there any way at all you can get the bike warmed up for 5 mins hot
remove both plugs out
Put a compression tester in front engine , crank full throttle for 5 seconds.
Do the same for rear engine.
Can you tell us the compression figures.
I feel like it is very important to start there 1st before i would advise anything else for that matter.
Similar issues last week , a client of mine said he needed a new engine which we helped him get despite me cleaning his carb & tuning it twice. His rear engine had low compression!
I hope it is not your issue but it is usually overlooked , she’s a big girl!
