Hi to everyone, the original compensator on my 09 was replaced about 6k miles ago. (July 20, 2012) I haven't put a lot of miles on bike since then because I had back surgery which kept me grounded for a while. I requested the latest SE version at the time. My service repair order says the part no. is 40274-08. My service repair order also states that at my request a "SE" compensator upgrade was installed. Well it works fine, but it is very noisy until I ride for about five miles.( it wasn't noisy when first installed) Any comments would be appreciated. I think there is an improved version since then, but I don't know the part no. Just for the record at the time I took my bike in there was a little oil leaking from the stator plug. The tech said that anytime they see any oil leaking from something they are obligated to investigate it and repair as needed. I am still under warranty. Just wondering if I should live with it, or take it in and have the most recent compensator installed. Thanks in Advance CAHDBIKER
