While you are all on the subject of exhaust and before Doug notices this when doing his suggested pre-ride inspection, both of my GZ250's, the '01 & the '06, have a small hole drilled on the underside of the pipe between the y and the muffler. I discovered it when I was looking at something under the bike while it was running, and I felt a little puff of exhaust. I found the source, and when I examined it, it looks like it was drilled with a .100 drill bit. Then I checked, and the other bike has it too. I can't imagine, in my wildest thoughts, what that could be for. Any time I have ever seen a hole in an exhaust pipe, it has been because of rust or a problem! Anyone have any idea what's up the the hole? Easy, I just know you will have a perfect explanation for this....don't let me down now... :cool:
By the way, since I know you guys are HUGE fans of short pipes with no mufflers, I have to pass along that I cranked up the '06 after an engine rebuild, and it sounds really good with the left tube disconnected from the main tube. At about 2K RPM in the garage, it almost sounded louder than my son's moped! :2tup: Don't worry--the police didn't come and arrest me, so it's all good.
I can't help agitating, y'all know that by now....lol
