wondering what temp range is desired on a mychron egt lead on a superstock kt100 with RLV L4 pipe, walbro wb3a carb on gas and on alcohol...Thx!
Nice Pic! Old skool NCK at Sears Point. Love it!The real advantage of EGT, it is "real time". Its whats going on now, not 30-45 seconds ago like head temp. Also ambient air temp doesn't affect the reading. The ambient air does affect the mixture or tune though. The Mychron numbers are so small they are hard for me to read underway. When I used a Digatron I could tune the needle and watch the temp change as I turned it. In the photo tuning and watching the gauge.
Thanks for the info2 stroke wet line tuning sets the correct flex length from the face of the piston to the junction of the first cone. Expansion chambers work on the principle reflective pulses first drawing the fuel charge through the cylinder out the exhaust and then rams it back into the cylinder to pack the cylinder for the most fuel charge. The flex length determins if just enough fuel is left outside of the cylinder to prevent over heating or worse. To short flex and the wet line is to close and hot to the piston, to long and the wet line is to far from the piston face and the fuel doesn't get rammed back into the cylinder efficiently. With the KT or other kart engines we are only concerned with tuning for wide open throttle. About an inch to inch and a half from the beginning of the manifold cylinder juncture. It is where we settled for safety and performance.
This same principle works for dirt bikes too. Difference is the dirt bike needs the carb tuned for the three stages of carburation because the flex is not adjustable.
