being that i live in fl. i am probably at a similer sea leavel as you. i put the Septres on my bike and have not rejetted, i know i probably should for maybe a couple more ponies?? but i havnt. i am not running to lean, she is a little lean but she comes that way stock, my plugs have looked very good each time i inspect them and that is about all i can go by. but i have been runnug her that way since before she was broke in all the way, so that is pretty much all she has known for exhust hahahahahahaha i talked with Todd after running them on the bike for a few months, told him what the plugs looked like and the increase in power she seemed to have and he felt like i did that because of the sea level air, i probably was ok. 5 yrs later and all is well.
