Major Sudden Sputter
Posted June 26, 2006 - 06:43 PM
Then I came back went back up two clips on the needle and I felt very little difference. It still does the same thing. Am I not putting something back in? It ran okay the first time, then even now with only going one clip lower than what it was it still runs horrible. It almost runs better with the choke on, but pops like crazy. HELP!!

Be sure to line up the header on the outlet gasket evenly, hold it in place and tighten bolt and nut evenly!!!
People just throw them on their bike, not paying attention to allignment.
You will be amazed at how a little exhaust leak can create havoc.

Then, you raised the needle an enormous amount, and got the results you should have; the bike ran hugely rich at part throttle, and stuttered badly.
Return the needle to it's original position. The only jetting changes Dr.D recommends for that system is to move the needle on an '03/'05 YZ450 DOWN one to the 3rd position. You went the other way.
When jetting, You change the main first, then the pilot, THEN trim the needle height. Go by how it runs, not by the plug.
