[QUOTE="whenfoxforks-ruled, post: 1416256, member: 73147"] On any given day, there is but 1 proper main jet. The one that runs clean, no surge, no blubber. It is THE only jet you can READ the plug. Running a 2 stroke MX engine at wfo is the goal, and more fun if you win. They have rev limiters to keep them from going ballistic. It is not designed to run at max rpm for long, it will over heat, cause pre-mature wear and fail. Jetted wrong, worn already, are but 2 of many reasons for failure. I run mine as fast as it will go, then what? I back off a tad and cruise, what is the big deal? That is on gravel roads. An MX track, that most was designed for, I very seldom hit peak rpm, much less wfo, except for the start. What is left at the end of the power band? Nothing, so why go there? Older and getting back into MX, I lug the motor a lot, but try to keep it in the meat of the power band. I like it right in the middle, just enough pull, yet not loading the engine up. A good motor should last 30 minutes plus 2 laps, at WFO. Then you need a rebuild. Vintage Bob [/QUOTE]
