View Full Version : Two-stroke electric power jet carb?

Can someone point me to a thread or explain how a TPS (throtle position sensor) and EPJ (electric power jet) carb is used/setup on a single cylinder 2-Stroke.
I have a digital ignition that can take input from the TPS and control the EPJ as well as run a 3D ignition map.
I have been sucessful in setting up and using the digital ignition in 2D but would like to know more about the possibilitys of using a carb with TPS and a EPJ and how it can be incorporated in the ignition map.
Thanks..........

Looking for the same info TZ
I think the kx had one thats all i can find so far and I think the tzr250 v twin SP had the similar set up that looks like it could be adapted to others I seem to remember the alloy frame cr125/250's with the mikuni carb had some electronics on the carb can't remember what though the search continues........
Keihin Power Jet PWK36 Carburetor with K-TRIC
• New jetting pumps up power delivery in the mid-range
• 8mm longer intake manifold increases low and mid-range power
• Kawasaki Throttle Responsive Ignition Control (K-TRIC) uses a sensor and alters ignition timing according to throttle position and engine speed for better throttle response and more power
• Power jet system uses an electronic solenoid to close a fuel passageway at 9600 rpm to extend the power peak and increase top-end power at over-rev
An all-new 36mm "shorty" Keihin Power Jet carburetor is fitted to the ’99 KX125. The new carburetor places the main jet, slide and needle 12mm closer to the engine for improved throttle response, and the all-new K-TRIC sensor provides quick acceleration. The digital capacitor discharge ignition (CDI) unit now alters ignition timing according to engine speed and engine load as indicated by the throttle opening. This produces a three-dimensional timing map to improve acceleration and throttle response, especially from low speed to about 1/3 of full-throttle.

What exactly is it you want to know or do? Presumably you're wanting to extend the overrev?
