Thanks guys... however... this EXACT problem happened when I first got the bike (super lean), when I put in a 115, and now it still exists at 120. My needle is shimmed already.
I did a plug chop, looks really good. Maybe a tad on the rich side, but acceptable. It feels like it is losing fuel when it stutters, but I doubt it. Lines are all good, it has good gas.
So.. electrical? Plugs look good... Bad CDI? Bad plug wire? What known problems exist with these bikes that can cause this problem???? This seems like a more rare issue, but like I said before THIS IS A KNOWN ISSUE, I have seen it posted on here before but no answer was ever established..
