raptor sputtering
I just changed my jetting and filters on my raptor and now it is sputtering when i give it any gas and it backfires. There is no airbox, dual filters, 160/165 jetting and 2 3/4, 3 on the mixture screw. Does the sputtering mean it is rich or lean? what causes that backfire? how long do you need to run your engine before you can tell if the color on the plug?

You might try the 155/160 setup....The best way to check your plug is to run a few miles on it first to get some color.Run the bike under a load for about a minute or so at 3/4 to full throttle then pull in the clutch, hit the kill switch but leave your throttle wide open all at the same time....coast to a stop and then check your plug.Try that if ya can and that should tell you if you are to rich or not.hope this helped a little.But hold on and keep reading cause there are a bunch of guys out here that know way more stuff then I do about jetting and I'm sure you'll get some better advice.[img]i/expressions/face-icon-small-wink.gif[/img]
