There have been numerous problems forthe '08 and up Buells.
I traded in my '05 Buell for an '08 XT and have regretted it ever since!
I've had fueling issues, surging, pinging, excessive heat from the right side of frame, hard shifting.
The bike is a dream as are most Buells in the tight stuff, but load it down and try the same curves and it's a nightmare.
I bought an '05 ST1300 in July to replace my ULY and can't believe I waited this long to get a Honda.
Stick with the ST and wave at the ULY riders waiting at their stealerships for parts or repairs...
