250-500cc WR 250 non start

Hi folks my names lee, im new here.
I've got a husky WR 250 (think it's a 96) and i cant get it running, im getting fuel and air ok.
I've fitted a new spark plug, is there any common faults from the HT lead or coil i should be looking into ?
any help would be highly appreciated.


NOTE; i received the bike as a non-runner.

Could be many things. Are you getting a spark at the plug?

nah i took it and cranked it with the spark plug against the crank case.

if you have no spark the 1st and easiest test is the kill button
disconnect it and try again, if not,,
when diagnosing do ONE thing at a time
I guess you have or plant to take the tank off
look at all the connections, unplug inspect and reinsert the connection, this is where a little old school wisdom helps, you plan to ride in the dirt and really hope to do some cool creek crossings, well all of these things are EVIL to electrical connections, buy dielectric grease and after you inspect and or clean any connection add dielectric grease and you will prevent connection corrosion
typically these are low voltage connections and any loss of voltage takes you out of your working range for performance on your ignition
hope this helps

+1 on the kill switch

Cleaned all the wiring terminals and carried out resistance tests where i could, no broken wires.
Put a voltmeter onto the live from the stator and im getting a reading when i try and start the engine. Coil pack and ht lead then ?

I noticed in my 99 book there is a module in the case of the wr it is a 2 wire
not sure of it's function as I have never had a reason to look, but probably one of the 2
at this point I would find a proper troubleshooting guide on this model and year as parts replacement is the cure but might not permanently solve the base problem

I had a stator winding go bad on a bike (not a Husky, but still...), it just failed randomly and the bike died, and it would never start. I took the cover off and ohmed out the windings, all were in spec except for one that was open (or maybe it was a short, I can't remember). In any case, it was clearly out of spec, and a good used part fixed it up, never had a problem again.

The ignition on these is pretty simple. I'd try to find someone semi-local with one that runs, and just swap the few parts until it runs. If that is not an option, try to find someone selling some used parts.

Sometimes you can ohm out a coil and see if it is bad, and some shops have coil testers. I'd check the coil and the stator with an ohmmeter first, it's the easiest thing to do. Then start swapping parts...
