  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

250-500cc Ducati Ignition specs

It's been almost a year since I had shoulder surgery and I'm considering getting back on the bike, but I have to address the no spark issue. I don't want to spend any time or money on the Ducati ignition. I'm going to kick it as far as I can. I can't remember the thread, but someone posted about HPI and I contacted them about their ignition system. They have one listed for the later WR250 and he said they should work but asked about the Ducati rotor size and wanted to know if there was a drawing for one. I can't find much info, if any on the net. Is there anyone that has any real specs on the Ducati setup? Ignition curve would be nice to see also.

I took my flywheel and stator plate off and took some measurements and pics for HPI. I'll let you guys know if it works out and I get it running again with the HPI stuff. Once I get it running, I'll be sending out the suspension to get revalved, so it will be some time before I even think of riding again.

send it to WER and you will have it back in a week or very close to it. they get ON it, packed much nicer than how you send it.
 
Right now, lighting capabilities aren't on the top of my list and I know nothing about ignition curves. Can anybody tell from looking at these curves how they will perform? It would be nice to know what the stock Ducati curve looks like.

Have you considered replacing only the stator with a new oem or other? A year ago after hitting a stump fairly hard my '11 300 began stalling out after it would reach normal running temps. Thought it was a fuel delivery issue or other electrical issue as I had spark at low temps but not a normal operating temps. I consulted Bill at BMP in Salem Oregon and he suspected the trigger wire in the stator may have been damaged. As a last resort I ordered and installed a new oem stator from him for about $150 and the problem was fixed. No more spark lost issue. Starting also improved.
 
I'm not sure what went out and there isn't any real info on troubleshooting the Ducati ignition. I did have an oily substance on the bottom of my CDI, so I suspect it. However, I don't want to through a bunch of money with the shotgun approach at a system I don't have confidence in. I ordered the HPI kit with the lighting option. Hopefully, it will work. If not, I'll try to locate an earlier analog system from a WR or CR.
 
Good luck and keep us posted. How much for the HPI unit, and does it come with a new stator or do you send them your oem one?
 
Everything is brand new. 195 Euros($210 as of today) including VAT and shipping. I don't know what the wattage of the stator is, though. It looks quite a bit smaller than the Husky one. It might be an waste of time, but I'm curious to see how it works out.
 
I received the HPI stuff yesterday. I was quite surprised on the fast delivery from Belgium. The flywheel is quite a bit smaller than the the WR's. It's definitely going to need a FWW. The HPI stator plate measures 94mm where as the Ducati measures 110mm. The slotted holes in the HPI stator don't line up with any bolt holes on the bike. Besides the 2 holes(yellow) for the Ducati stator, there appears to be 2 other bolt holes(red) that I'm guessing are used by the CR stator. There are 2 holes(red circles on black stator) that seem to line up with those holes, but there is a raised portion(blue arrows) next to the holes on the bike that are there to center the OEM stator and don't allow the HPI stator to sit flat and I won't be able to adjust the stator since those holes aren't slotted. I've got an email into HPI, but sometimes he answers right away and sometimes it takes a few days. I have to go out of town for work for a few days so I won't be able to attempt to install for a while.



WR vs HPI flywheel



WR stator vs HPI. Instructions say it's a 60 watter.
 
Either im going mad or my eye sight has failed me completely - But im seeing the hole in the new flywheel as being much larger and has no key way !!!

Same size hole but yes, no keyway.

I got a reply from HPI. Apparently, I should have received the 110mm stator plate. They offer a 300g flywheel weight, so I ordered that and they'll send the stator plate, also.

I was wrong. :mad:
Any trig experts here? I got the 110mm adapter plate and went to install everything and realized the HPI rotor(flywheel) has a different taper. I'm hoping there is someone much smarter than I that can figure out the degree of the taper. Unfortunately, HPI doesn't put any part numbers on their stuff and I'm trying to figure out if they sent the rotor that they think fits the Husky or a wrong part.
Measurements are approximate, but close enough to get an estimate of the taper.
Ducati flywheel
Large end 17mm
Small end 13.35mm
Length 22.25mm

HPI Flywheel
Large end 19.50mm
Small end 15.75mm
Length 28mm

From your measurements they have sent the wrong flywheel.

I realize that, but I'm trying to figure out if the the flywheel they sent matches their online specs of the part they list for the Husky or if they just sent the wrong part that has different specs. I'll just have to wait to hear back from HPI.
 
This is frustrating. :banghead: I really don't want to install another 11+ ignition system and so far the HPI stuff has been a struggle to get bolted up. Communication with them has been a little annoying. I'm getting responses to my emails, but not the answers I'm looking for.
 
HPI sent me a template with different tapers and it appears that the taper is not 4 degrees like HPI says it is. It's closer to 5.7 but not quite. I think the 5.5 degree might be closer fit.
