No fire 1998 XR250R help please.

Recommended Posts

Guys,   I would really appreciate some expertise here.  I have no fire so I troubleshot a little bit and I was reading good across the coil at .3 ohms, and then 375ohms across the stator.  I bought a new stator and a new CDI box.  Installed both and still no fire. 

I still have .3 ohms across the coil and 190K ohms from both sides of the coil to the spark plug wire electrode.

I now have 320 ohms across the stator (Ricky stator) and a new OEM CDI box.

Can someone give me a hand with this?

So I wasn't getting any voltage (.7V) at the CDI box.  Ordered the Ignition pulse generator.

 

The bike is going on 20 years old.  It was all good money spent as the entire electrical system will be new.  Lol

With all of my years of fussin with XRs I've found the Honda electricals to be very reliable, have said that there are some DC powered CDI modules like on the XR650L that have a rep for failure. 
I have found some problems that can cause loss of spark:
Spark plug
Resistor in plug boot, unscrew plug connector and replace with a solid piece of metal.
Bad kill switch or wires, very common for wire insulation to be pinched off and short. disconnect and test.
Poor connections, I clean all connectors with electrical contact cleaner and use dielectric grease to seal them from moisture.
Poor or corroded connections and/or ground. Ground point should be tight and clean to bare metal.
The paint on restored frames can insulate the engine from the chassis, I install a jumper wire from the head to the frame ground point.

Thanks for the suggestions.

Spark plug = new and multiple ones at that.

Plug boot = I am getting continuity between the coil and the plug contact

Kill switch is completely disconnected

Good idea. I need to clean all the connections and put some grease in all of them while I have it apart.

Good idea as I have restored this frame but it has been a few years.

What helped my find my "no fire" problem was switching electrical parts out with a guy with the same bike. Turned out to be a CDI my guess was it shorted out from when I disconnected my battery (e-start xr400)

Replaced the igniter and the coil.  Still nothing.  I am going to take a bunch of resistance measurements and voltage readings and post them up.  The entire electrical system is brand new now.

I found that sometimes my key switch plug disconnects while in turns. I'd go through and make sure every plug is making contact if you haven't already. Other than that I'm stumped for now...

I picked up a well used 2005 CRF250X for $1100.00 for my son to ride.  He is stoked and I didn't like him throwing his leg over my XR anyways.  Need to put about 500.00 into it to make it reliable.

 

Wife looked at me and said "You are going to sell the XR now right?"  I said...."Yes"  knowing full well I will never sell it. Lol
