Any help would be great. I got the pipe fixed up really tight, checked for leaks around the exhaust port, no bubbling when I spray stuff on it, no rpm change with carb cleaner....
up jetted to 68-- four stroked a lot, 64 was the next one I have.
The big problem I'm finding is there's a crazy high-pitched noise when I hit 20mph. Wasn't there before, is that the sound of the pipe or is it a bad demon inside my engine?
I haven't been riding with the pipe long enough to mess up the engine
