[QUOTE="MX-727, post: 502041, member: 19400"] Tony, most folks warm their bike up for about a minute, lightly blipping the throttle. A good rule of thumb, is that when you can touch the cylinder and feel it starting to heat up, you can take off and ride gently for another minute. After that, let it rip and go ahead and wind it out to "blow it out." If your jetting is slightly rich and you are doing a prolonged warm-up, you can foul the plug in a manner that the bike will continue to run, until you shut it off and it cools down. When you go to restart, you will find that it is very tough, if not impossible, to start. So, you then check the plug and find it's fouled, and you are confused because it was just running. Read the jetting guide on Eric's site: [url]http://ericgorr.com/techarticles/carbtuning.html[/url] Also check out Canadian Davis guide: [url]http://justkdx.dirtrider.net/carbtuning.html[/url] Just do it, you'll learn a bunch and it will help you understand what all of these people are talking about. My general belief is that most bikes are jetted rich out of the factory, so one leaner on the pilot and raising the clip one position is my starting point. I wholeheartedly recommend that you talk to people in your area that have the same bike and talk to your shop to get an idea of what jetting has been found to work for your bike. Then, make those changes, put in a fresh plug and ride your bike in an open area. Get your bike jetted and running well before you tackle the woods. Then you can figure out if you need to change the gearing. If you spend a weekend getting it set up and learning how the bike responds to changes, you will end up with a bike that will be, with normal care and maintenance, trouble free for years to come.
