the temp depends on where you point the optical thermometer and how fast the wind is blowing over your bike
the engine is not really designed to sit and idle in a garage - idling has the most delicate balance on the fuel/air ratio, because its using so little of both.
Is the bike running ok while riding? if your crank it WFO in 4th gear does it growl and take off like bats from hell?
popping on deceleration is normal if its slightly lean, if you have aftermarket exhaust and the jets and PMscrews were not changed and adjusted it will be just a bit lean
if you are putting premium gas in the bike (it does not need it, uses regular) it will be even more lean
If you are running regular 10% ethanol, you could try to find a station that has regular octane ethanol free gas, that will run a bit richer, and see how the bike behaves. There are some stations around that sell it, esp for older cars, lawn mowers, and other small gas engine that dont run well on E10 fuel.
when you start the bike pull the choke all the way out, dont give it any throttle, and as soon as it starts push the choke halfway in, check your signals and lights, and ride off. The oil pump will push more oil up thru the engine if you ride it, better than letting it sit there and idle.
About 1/2 a mile down the road push the choke in all the way.
for the rest of the day you wont need the choke again unless the bike has sat cold for several hours.
If you think there is a vacuum leak, you can use an unlit propane torch to gas the area where the leak might be, or carb cleaner - if you hit a leak area the idle will speed up.
