This 250R can be viewed, inspected and test ridden before auction end by appointment! I'm an electrical engineer, and even I have pulled my hair out trying to find ignition problems, and I'm supposed to be an expert at this kind of stuff. I've got a good running 85 atc250r that I was thinking about switching the stator with just to se if that worked. I'd try a stock stator. Did you pull the plug and look for spark? They both had the stock tires, grips, etc. The seat cover is a Brand New replacement cover. I have worked with a few shippers in the past and can give you their info if interested. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
It is essential to use a spark plug that fits a specific engine and its conditions of use. I am pretty sure the shop that it was at had tried bypassing both kill switches, but I will make sure of that too. Thanks for the reply wilkin250r, the plug was getting spark at all times. As for different heat ranges, here is the blurb on that Heat range selection is vital to ensure optimum performance of spark plugs. Sometimes, problems can be difficult to find. It has a new cdi box 3 have actually been tried , new stator, and new coil. The thing throwing me for a loop is that the 125 box makes it fire.
The main connector problem is the one with the black wire with white stripe, that the main ignition wire. These Vintage 2 stroke Honda Quads haven't been made in over 29 years, are becoming collector's items and are getting harder and harder to find! I never had a problem or had the lights flicker from the b8es plug. Now you have the flexibility to select an ignition that will work best for your particular application. Basically i would kick it over, and get nothin until the motor stopped moving, then it would spark once. I think I am going to start testing parts back and forth until I come up with something. Everything ohm'd out fine with mine too, but no way to check the magnets! I have the 88' and the 85' sitting next to each other in the garage right now. No air leaks that we could locate.
Think we got it figured out but won't be totally sure till Saturday. New 250R owner here with a problem someone might have experienced. I forgot to add I did run the extra ground off the coil wire, and I have no key, but I do have a dead man. Curb weights are listed in pounds. Run an extra ground wire from the ground wire mount at the coil to the engine block. I figured the 250 cdi shouldgive th same, but maybe not I guess.
I know it a slim chance, but i wonder if someone changed these before. The main reason for the resistor is for as mentioned, to keep interference out of radio frequencies. Originally posted by regg187 Think about this first. As for different heat ranges, here is the blurb on that The old spark plug is very complicated and can cause serious damage to your engine if you chose the wrong one. We had already eliminated a fuel delivery problem.
Then consider so that you may make posts, and view the additional content available. Hope this info atleast helps somebody. It appears to be something electrical and I'm sure I will find it eventually but thought I would ask if anyone had run into this problem before and might be able to point me in the right direction quicker. A spark plug's optimum operating temperature is between 450 degrees C and 870 degrees C. Are all your wires tight in any crimp terminals you may have, no oxidation? The headlight lens has a crack, but the light still works! Thank you for viewing my ad and have a great day! I will do my best to answer in a timely manner. If it starts for a few seconds and dies, then you have a fuel delivery problem. Forget it completely, don't hook it up, and don't use it to test anything, and forget any information that you think it might be telling you about the rest of the circuit.
Technical assistance such was wiring diagrams, old brochures and specifications, performance modifications, and much more. If it's an air-leak problem, there's no sense in changing electrical components. Some say it fries your cdi, others your stator. Outside in the sun you might not be able to see it. I try to take good pics and have a good description.
Our original thought was that maybe the coil had a weak spot and once everything was up to normal operating temperatures that after expansion we were getting a weak spark. I used a br8es and it seemed less pwerfull. If we have the Canada, Euro or other edition information it will be identified as such. Outside in the sun you might not be able to see it. Hello All, First time poster here and apologies if this is in the wrong location.
If it doesn't spark, we found your direction. The old spark plug is very complicated and can cause serious damage to your engine if you chose the wrong one. I have wiring diagrams, but it doesnt tell how the connections go into the trx250r cdi. ??? Alternatively, you may also now if you already have an account. Heres the blerb regarding resistor plugs. Please know or learn how to jet and tune for your location and conditions. Dirt bikes and Scooters mopeds are listed on a separate page.
Some quads do not have a battery, so nothing is in that column. It was a small gap easy enough for the spark to jump, but it would still ohm out as an open circuit, so it was very difficult to diagnose. You would be surprised at how many variables there truly are. Viz: When the heat rating is too high: The spark plug temperature remains too low and causes deposits to build up on the firing end; the deposits offer an electrical leakage path that gives rise to loss of sparks. . Please call us for information on programmable systems. I had a problem with my ign earlier post 'intermittent spark' finally figured my flywheel was going bad -magnets- got a ricky stator lightend flywheel and I am as happy as can be.
