Re: To all of those that have drilled their own jets
I had a problem with my bike a couple of months ago, when it was hard to start and ran very rough. I thought it was a bad spark plug or wire, but after an hour or two of checking things out, I discovered that the four bolts that hold down the magneto had become loose inside the cover, and allowing the mag to wobble around. That was all it was! Take a quick look at your magneto bolts. Another clue would be that you reduced the plug gap to make it fire. That's an indication of a weak spark coming from either your mag, CDI unit or bad plug wire, Take a close look at your plug wire connection to the spark plug.
Change is inevitable and progress is OPTIONAL!
