I lowered the back of Wendys bike 2" and haven't lowered the front. I lowered it for about an hour and it scraped too easily so I put it back. There have been no problems with oil pressure or anything else. It rides nice and handles good,so I would offer that it's a matter of choice.

I learned all I need to know about life by killing smart people and eating their brains.
