I did my first oil change tonight after installing the new bars. Yeah, that was no fun. It is also made more difficult by the oil pressure sender to make the oil pressure guage actually give you readings rather than the constant stock reading and I think the DOHC swap made it more difficult too, the hose routings I think are probably more in the way. So, to ge the filter out, I had to push it up and back as far as possible, work it in between the overflow tank hose and the sway bar by forcing the hose out of the way and kind of wiggle it out by passing it along the top of the sway bar. This got real tight in a couple places and things that are semi flexible had to be forced out of the way. Getting the new filter in was equally difficult if not harder. I am tempted to take it to Jiffy Lube next time just to see them try and figure it out.
