    But this isn't a yz250 it's a blaster still think that would be it? I have a feeling it is as a security feature or maybe I was wondering if there was a safety neutral switch on them

A blaster will still start & run with out an ignition swith the only the the switch does I'd ground out the ignition system you can just unplug the key switch and start it my blaster and banshee bot start with the key switch unplugged it comes in handy when you head out to the sand dunes for the weekend and leave your bike keys at home

Your bike should still fire as long as you have linked the 2 wires from the ignition switch

Jd lawn mower was only firing on 1 side coil and i changed coil so why is it still not firing


You only have one magneto on the flywheel, this is how any flywheel is designed because both cylinders can't fire at the same time, so why have two magnetos to fire one coil? Anyways, the magnetos on flywheels from my experience hardly if EVER go bad, and coils today have so many capacitors and resistors and diodes inside that even the slightest amount of heat soak from a poorly maintained engine can fry the circuitry and fault a coil in a flash. If you replaced te coil and it won't work, try to swap the coils around and see if the one you know works won't fire on that non-working cylinder, that way you can be sure the new coil is not defective, which I've seen many times as well. When it's running, do you pull the plug off the dead cylinder and see if it fires, then repeat the procedure on the live cylinder with the dead coil installed on the plug? Will it fire at all? Try to disconnect the kill wire from each coil, then start the engine and see if both cylinders fire now. I have seen some engines, as an example some briggs vanguard v-twins that have a diode right in the middle of the kill switch wire. I don't know why it's there, probably to deal with spikes in current or something, I'm not that great with electrical I just know how a simple ignition system works and I know if one coil fires that plug, the other one should too. As I said, things from china areive defective all the time, it wouldn't surprise me if that coil is defective or if it runs with the kill wire disconnected from the coils, then there may be a diode blown in the line or you have a chafed area of insulation that's grounding to the book somehow. Pull the kill wire and fire it up, then swap coils, you'll be able to tell what's wrong once you rule out one or the other, it's just a simple process of elimination for a simple problem once it's explained to you. I'm sure you'll figure it out and be back running in no time I you attempt my suggestions!

1977 yz 250 isn't getting fire


Check the points for proper gap and clean. The old school bikes used more than just coil and plugs. Also, often overlooked, check the kill switch connection. Often this is the case on Yamahas.

1977 dt 175 e and i can't get it to fire i put a new coil and still no spark


My old 73 175 had points, I don't know if yours does. There is also the stator/ magneto. Try disconnecting the kill switch or unplug the key cylinder. There is a more detailed check in the manual. I can't find my old 175 manual but ttr125 says 1) check plug for spark- clean or replace. 2) check entire ignition system for connection. 3) check ignition stop switch. 4) check coil. a- primary coil, b- secondary coil. 5)check cdi coil. a-pickup coil. b- charging coil. Since you have replaced the coil I will only give specs for the cdi check. The picture shows a plug under the tank disconnected. It has four wires brn grn red and wht. To check pick up coil resistance set ohm meter to x 100. attach the plus lead to red and neg. lead to white. It seems to have a short wire in each jaw of the alligator clips of ohmmeter that is pushed into the disconnected plug that contacts appropriate wire color. Reading should be 248 to 372 ohm at 20 degrees C (68 degrees F). Charge coil test places the plus lead of ohmmeter to the brown wire and neg. lead to the green wire of the open plug. Meter at x 100. Reading should be 688 to 1032 ohm at 20degrees C. Of course while doing step 2 check for good grounds and tight connection at plug cap and use a new plug. Good luck.

Do u know the firing order for a 89 suzuki


89 Katana uses two coils, one fires cylinders 1 and 4 together and the other fires 2 and 3 together. It's a waste spark system. So your firing order is either one coil or the other every revolution.

I have a yamaha r1 2001 no current to plugs 1 @ 4 tried everything change coils cdi box harness rectifire nothing works


hi,about the only thing you havent replaced is probably the culprit,it sounds like one of the pickups has failed and gone open circuit,this will tell the cdi unit that the pickup has already fired and not send the voltage pulse through to the coils,hope this helps...cheers

I have a 1985 xv700 virago. one of my plugs are misfiring. I had issues with my original one. yamaha dealer told me i needed a new cdi box. He sold me a used cdi igniter box from a non running 1985 Yamaha...


follow the plug wire back to the coil and see if there are any breaks, if not might switch coil with the other one and see if the other plug now misfires, if so replace the coil, most cdi problems are not intermittent, typically they either work, or they dont.
