This is the same for me. I haven't run any game system without tinkering somehow with it.I'm a tinkerer by nature. One of the real joys for me as a DM is not just creating a setting, but getting to put in whatever house rules I want. That is actually as much a part of the DNd experience to me as killing monsters and takin their stuff...at least when I'm DM.
That said, in my experience the best houserules are the simple ones. You can build a brand new totally custom system...but people tended to respond better to systems that are familiar and intuitive enough to pick up quickly.
Further, I talk about houserules a lot more than I implement them. I probably only implement about 10% of the houserules I kick around or discuss on forums.
However, 4e has been pretty solid for me so far, with only a couple tweaks implemented; Stalker0's Skill Challenge, Dan's encumberance rules, and expanded wounds. I think the use of the DDI has restricted my penchant as I would like to change a couple things in classes and races, but its easier to have my players use the DDI as is.
