250-500cc 2014 WR300, another failed Ducati ignition....

So my '14 WR300 has roughly 50 hours on it. Has been great until recently. Started running poorly (constantly loaded up on the bottom, never clean out on top end, missing). Started to foul plugs in short order. Less than 26 miles it ate 3 plugs. That last on only gave me about 90 seconds. After getting it out of the woods and back for testing.... Very weak spark if it will spark at all with a new plug.

Anyway, I have looked at several threads here. Seems I would need the stator, flywheel, coil, CDI (stock or try and get a JD racing unit), and the nut/washer from a older model CR. Read a lot about using '02 CR250 parts (MOTORHEAD's recommendation), but have seen HPI's parts in a thread here as well (looks like it was a mess to get correct).

So what have others done when their Ducati ignitions have failed?

What parts did you use?

Are '02 CR250 parts still available?

Words of wisdom?

Thanks,

Heath

Mine had a weak spark after @ 50 hours too. After looking at those same threads and info I ordered a new OEM ignition instead. Maybe I got lucky, but after another 60 hours still have a strong spark and bike starts and runs great.

Sounds like I need to buy a spare for the 165 next

I've got 270 hours on my 12 wr300 and apart from one instance when the plug cap gave me some grief it has'nt missed a beat.Still original bottom end. However have just bought a Sherco 2018 SE R 250 and love it so far,the electric leg is kinda nice after 8 years without one.

I'm not real excited about putting another Ducati ignition on the WR after it failed at 50 hours........... left me in the middle of nowhere........ pushing a bike through single track........... in the mountains of Tennessee........... and killing a ride that had been planned for close to a year.

Anyway, can't cross this bridge until I get my soybeans planted.

I hope I can find a good reliable alternative to the Ducati setup for the WR. Until the failure, it has been the best offroad bike I've ever owned.

I've emailed a couple of Husky parts suppliers online looking for older model year ignition parts. Not heard back from any of them yet. The CR250 ignition with a flywheel weight and JD dual map CDI sounds like a great set up, but I wonder if those parts are still easy to find after the Husky's became white KTM's.

Heath

Have you looked on ebay ? They pop up from time to time.

I have seen HPI's stuff on there. Guy in Michigan (I believe) is selling them on there. Not seen the entire ignition system on there yet.

Might be best to get an older WR ignition set up from a wrecker. My 250 starts so easy compared to the newer 300 I had . Crs are probably a bit snappy for technical riding even with a weight the flywheel is still going to be lighter

Like I said, my replacement Ducati ignition is a lot better than the original. Bike starts easily now, fresh top end helps too.
I see the pre Ducati ignition parts available online:

So finally I now have a CR250 ignition with a flywheel weight. Gotta find a flywheel puller before I can start swapping the Ducati stuff for the Kokusan parts.

The question I have is, how do you set the timing on the WR?

Thanks,

Heath

This is the correct flywheel puller?

Heath

Can't find it now, but noted the thread size somewhere.
The correct tool is available here:

Got it ordered. Thanks man.

Gonna be here next week hopefully. Any tips on setting the timing once I swap the ignitions out?

Heath

There are marks on the stator plate that line up with the marks on the engine case.

Hi, the kokusan flywheel of my WR300 2010 is M22x1.5mm right thread:



Cheers !

Just got a Husqvarna flywheel puller from MotoSport yesterday...
Looks like I’ll be in business after the holidays.



Heath

Got the Kokusan CR250 ignition installed, but I have a concern about the timing. There is a mark on the stator plate, but there isn’t any mark at all on the engine case. There wasn’t a mark on the Ducati stator either. I just bolted it in as close as I could guess. Anybody else had this come up on Ducati era WR300’s?
