Switch the power on for the digital multimeter. Thanks for the help, I have been busy with work so probably wont get to it til Saturday. Now I just wanna make sure I check it correctly. JavaScript is disabled. Heres where the EX 300 comes in. Some complain of a boring feel from these new fuel-injected two-strokes, but I am not in agreement. Put the negative lead on the engines ground and the positive lead on each wires of the stators connector one by one. To test the pulse (trigger to tell the computer when to send ignition to the spark plug) the motor needs to be turning over. Compare the resistance reading that appears on the multimeter screen to that given in the Honda 300 owner's manual. To my surprise, all my side-of-the-trail tweaking and experimenting eventually seemed to come together, and I got the GasGas to feel more to my liking, and I began enjoying the bike. Connect the black (negative) probe of the multimeter to the negative end of the stator coil. You shouldnt get a reading at all. Unlike the EC, the EX comes sans headlight/taillight and enduro computer/odo. So i continued on to again find the meter reading 11.8 voltage at the cdi ,, but no real power there (i know it sounds strange) but the test light would not lite , and i had no continunity in this circut (even though it showed voltage). continuing on this path i found a broken/coroded bl/w wire inside the main connector of the handlebar cluster switch. Electric starting also makes your life much easier with the EX. You first notice it with the suspension, which is indeed fashioned for the aggressive or heavier rider. The EX 300 is modeled after KTMs 300 XC TPI two-stroke off-roader. ahh and i checked the coil wires also , they seem fine. Showing how to check your stator, what a bad one tests like and what a good one should look like on a multimeter Well show you how to perform a motorcycle, UTV, or ATV stator test even when you cant get your machine started. Ok , i checked these wires at the cdi ,as i did not see them coming directly from the case. Im not sure Id miss the Xact forks, too, much because I like the feel of the WP Xplor coil spring fork that comes with the EC anyway and you pretty much just set it and forget. Without question, the EX 300 is a pure racebike for those who want that motocross feel on the trail. Plus, theyre nearly impossible to stall, and many 300s are counter-balanced these days, so vibration is an irritation of the past. So, when its GNCC, WORCS or NGPC, dont forget the EX. William Hirsch started writing during graduate school in 2005. Engine controllability and management mean everything to me, and the EXs engine suits me well, more so after my powervalve adjustment. Hi all, trying to find info on how to test ohms in the stator on my 400ex. As with the Ohms test, test between each lead of the connector (1-2, 2-3, 3-1) and note the readings. Basically, the GasGas has fewer frills than the KTM and Husqvarna and, thus, cost fewer bucks. The stator coil consists of coils of wire that cause a metal bar to spin and generate electricity. To test the pulse (trigger to tell the computer when to send ignition to the spark plug) the motor needs to be turning over. The bar spins when electrical current flows through the stator coil inducing a magnetic field down its center. . Hirsch holds a Ph.D. from Wake Forest University in theoretical physics, where he studied particle physics and black holes.

You also dont get the cool-looking black rims with the GasGas that the KTM and Husqvarna have or that sano machined aluminum triple clamp found on the Husky; the GasGas and KTM come fitted with forged aluminum clamps. Also thanks Too deep. what would ya check next? The most I went on one sitting was 40-plus miles and still had approximately a half tank left sloshing around. For a better experience, please enable JavaScript in your browser before proceeding. Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!! oh , and i have tried the original , and new spark plug. As much as I enjoyed riding the EX 300, I found myself trying to change it into the EC 300 by softening the suspension and smoothing out the engines bottom-end. Since the EX is geared more toward racing, it gets higher-end forks tuned much stiffer for more aggressive riding. Were a forum community dedicated to Honda ATV owners & enthusiasts. Resistance measures the amount a wire limits the flow of electricity. Unplug the 2 wire connector from your CDI. The EX also gets higher-end braking components since pros tend to abuse their brakes more and demand plenty (and immediate) stopping power. They should all be the same (E.g. and bty , Moose, ya have any new pics of that 250x build? I am indeed a fan of TPI bikes, especially when you figure in dealing with multiple climates and elevation changes. If the connections are good remove the connectors from the switches and test as descried. Does anyone no suggested ac volts that should be made at cranking speed? Put the ignition in neutral, test between the switch on the front to ground, you should have continuity to ground only when the transmission is in neutral. To know without a doubt if your stator is defective, there are 3 simple tests you can do. Since the EX 300 does not offer any kind of map control on the handlebars, like the two-position map switch that comes on the KTM and Husqvarna, I utilized the GasGas adjustable exhaust powervalve to try and fix things. Thanks! Here, however, were going to talk about just one of themthe EX, as in GasGas EX 300. Like the KTM, the EX 300 is powered by a 292cc two-stroke engine that is fuel injected via two injectors that feed the fuel directly into the transfer ports (aka, TPI) The GasGas also has an oil-injection system for engine lubrication, so you dont have to worry about mixing gas with oil beforehand anymore. Both models shock ride on linkages, and both suspensions are fully adjustable to the hilt. So long carburetors, your job is finished here. 0.2-0.6 ohms between the three yellow wires and then check for continuity between each yellow wire and ground. See if it has continuity to ground? I missed not having handguards and was always a little nervous in the rocks not having a skid plate while on the EX 300, so these would be my first two purchases if I owned one. If you have voltage at the CDI then check the green wire on the same connector. You can tell right away that this motorcycle is tuned for racing. First make sure they are securely connected. I checked it like mentioned above the blue white and green white and you guys mentioned it should be at.07 but I get 0.0. For a better experience, please enable JavaScript in your browser before proceeding. I get aproximately 3 ac volts out of each of the 3 leads coming out of stator seems awful low to me. Its worth a look.CN. The Fora platform includes forum software by XenForo. The multimeter reading should read about 0.5 volts for each. Copyright 2023 CycleNews. i will try these tommorow and let ya know what i find. Okay your stator is probably okay then. A lack of controllability, perhaps, but never outright power. They should all be the same (E.g. Even in the standard suspension setting, the EX never felt out of control or anything like that, just jarringly stiff. Just a side note. Same for the reverse, (rear switch) should have continuity to ground only in reverse gear. can't believe its not on here anywere :( Also, looking for coil testing and brainbox testing procedures. 20v/20v/20v). Otherwise, the EX fuels exceptionally well. 20v/20v/20v). If they are different, your stator is defective. Otherwise, they all arent much different. The translucent tank holds a generous 2.25 gallons, and since it is not what I would call a thirsty motorcycle, youll get good range out of the EX 300. Is there a way to check the stator once it's removed. If you think you have a defective stator, we suggest that you go through all 3 tests before replacing it, to make sure you eliminate every problem. Copyright 1995-2023 eBay Inc. All Rights Reserved. Never. Why Use a DVA Peak Volt Adaptor to Diagnose a Stator? Both bikes have WP Xact shocks, but the EXs is set up stiffer. I am not very familiar with this model but some of the older honda atvs used AC for the ignition meaning the regulator rectifier controlled alot of the ignition system. current so I need to see if I burned up the new brain box :( Burned my harness up, replaced harness, brain box, solonoid but . Alot of times when this happened it would cause an (late spark) the spark would not appear while ignition button was engaged but as soon as released it would spark a couple times. I removed the stator. The EX has all these things, indeed. The GasGas EX 300 is all about going fast. YOu said you bypassed the key switch and it fired up. Like all KTMs, the GasGas EX 300 utilizes a chrome-moly steel mainframe and an aluminum swingarm. RM STATOR is an industry leader in the manufacture and repair of electronic parts and components for powersports vehicles. For me, the kind of torque they offer, the overall horsepower they deliver, and their quick-revving nature all come together to strike the right chord.
