Mine fires right up, unless it has been sitting for two weeks or more. But start up after cams and tune and willingness to rev never an issue here. I would assume that you know not to rev these bikes hard until completely warm, and give it a bit of throttle on start up. Mine idles at 1000 rpm when at temperature. And, what's your tune? I went with Maximus. Full tune of A/F ratios all the way up and increased limit to 6300. Timing also set from idle up. She runs reeeeaaal good.

How are you starting the bike? Should be up off the kickstand, throttle cracked open a little and thumb on the start button until fully running. Then hold at 1200-1400 rpm for 15-30 secs before putting back on the side stand and letting it warm up more while you get your gear on.

mine has started the same when stock, after just a tune, and even when I added cams & had a re tune.

maybe your battery is getting weak? Do you have it on a tender? When cams and tune were done did it sit for a while?

when was the last time you checked all of yourmain connections? (Battery, 40 amp breaker, grounds, etc)

Often doing high performance work the result is poorer idle and a bit harder to start. In general this would be due to the compromises between power at mid and top vs low speeds. Sometimes the tune includes a bit higher idle to compensate for a rougher low rpm idle also.
