Good thing is my garage floor will never rust.
I did that in a minivan once and wife didn't catch it till too late. Got a pretty good knock, mechanic said to try some (can't remember for sure) Miracle 50??, anyway it worked till we got rid of it a few years later, very lucky.

Re: Super Duke disaster

Low mile bike, purchased from a dealer who did the maintenance for resale. Install the new engine asap and get this owner back on the road. Option 2 is to get another SD of the same mileage and year for him. Option 3 is a full refund and / or credit towards a new KTM.
I hope this goes the right way for you man, fun bikes.

Sounds messy Jay. That's odd, based on my Honda experiences with the Wing, which I have not any trouble with oil changes. It's also an automotive type filter with a rubber ring. Messy oil problems are some of the worst. I save cardboard boxes from motorcycle parts I order and put them under the bike when I change my oil. I seldom manage to change oil without ruining the box. 4 quarts though would have run off the box.

Didn't you have an issue on your Harley on a ride once where it lost some oil as well after a side cover came loose? I actually had a little oil leak Sunday on the Wing on the way to Orlando. I noticed the left foot peg was wet, but much more slippery that water. The right peg was dry? Stopped and noticed there was oil on the shift lever and a little on my boot. When I checked the valves last week, I didn't get the cover back on precisely. There is enough slop in the installation that it can leave a little gap at the top. I loosened the valve cover bolts, moved the cover may be a quarter inch and all was well.

I checked the oil a couple times on the SD within the five or six hundred miles I rode it. There is a handy sight glass for checking, as well as, low oil pressure and low oil level sensors. There is also an oil temperature sensor and I noticed that the oil temperature was running about 190, which I wondered if that was right or a little high.

190 sounds about right to me. The oil temp should be similar to the water temp in a water cooled engine. My water boxer's engine temp is 184 when running down the road. Fan kicks on at about 209. I assume "engine temp" is water temp, but I'm not really sure how BMW measures it to be honest.

Re: Super Duke disaster

I am sorry to hear that such a large investment has these kind of problems.

If it was started by the spark plug, could it be metal fatigue from someone setting the gap multiple times? I have never seen an engine blown over a plug but anything is possible. You might contact the plug manufacturer and see if there is an issue with this plug and force a recall. Again, I don't know it is the plug but it might save others.

Not exactly, the primary cover (that had been put on with Loctite) fell off on old 90 near Deavers after a trip up to the Pickett House. It lost some primary oil as well; that's how I noticed it due to the smoke from it baking on the exhaust. Jim and Michelle went to the Harley shop in Beaumont, picked up a cover, bolts, and oil, and I replaced it on the side of the road. When I got home and after another extensive cleanup, I put Loctite on the new bolts. I've always said, the only bolts you need to Loctite on a Harley are the ones you want to keep on it. Turns out that probably should be the only bolts you hope to keep on it. We never found the original cover that day, but Jerry and Barb went back the next day and found it on the other side of the road. I told him that if it wanted off the bike that bad, he could keep it.

Re: Super Duke disaster

Thank you!

A couple of thoughts. What bent the spark plug? Clearly an impact, but with what? Whatever it was, it may have gone out the exhaust valve. Did they look in the exhaust system for any debris? The piston appears to be relatively intact, despite the damage, but the oil control ring looks incomplete.

The only other time I have seen cylinder scoring like that was due to loss of oil pressure. Very odd indeed. I understand your frustration completely. I rode the same bike last week. Quite a machine, but the seating position was just not quite what I was looking for. Hope you're back on the road soon.

Re: Super Duke disaster

Well, the news is back from KTM. They don't have a "crate motor" per se, and they aren't going to give me a new bike, so ... Cycle Shack plans to rebuild the engine. They are getting a parts list together, will order and rebuild. I have had a chance to talk to and gain trust in the mechanic who is doing the work. He has several decades of experience rebuilding motors. I am a little concerned that we were not able to discern the problem that created this mess. So, now it's wait and see ...

Re: Super Duke disaster

I would continue to press them for a new motor. I do not see a rebuild ending well given he amount of loose metal and the time it has circulated.

I have a 2016 SA and my warranty just ran out, I am slightly nervous to say the least.

I have pressed, but you know how dealing with a dealer can be sometimes. I do believe they have pressed it with KTM. He has mentioned several times, that he has passed my comments and desires along to KTM. At this point, I might get my way, if I pressed for a new engine, but then it will be sitting in the shop all summer waiting for said engine, while the warranty ticks away.

I do know of several people who don't keep their bikes beyond the warranty period, because of the reliability concern. I will have to wait and see how this turns out and how I feel about it to know where I will go.

I have said that I am sure there will be the normal break-in, after the rebuild, but after that I plan to give it a good thrashing.

Perhaps the extended warranty on this bike is looking like a good investment.

Re: Super Duke disaster

IMHO having thirty+ years in the business, the piece of spark plug is the result of the problem not the cause. This looks like detonation either caused by pre-ignition or other causes. With computer controlled spark way too many things come into play to make long range trouble shooting possible.
The piston damage appears to be caused by explosion forces in the cylinder which could have blown the ground wire off the plug or physical contact with the piston, I'd need a closer look to make an educated guess.
A local rebuild should not be a problem IF you are dealing with a skilled mechanic. FINDING THE CAUSE will require someone with knowledge.

Wish I could be of more help.

Re: Super Duke disaster

decades away in technology, but the pictures remind me of my old iron head Sportster when it wrecked the pistons. turned out to be the stock ignition wasn't doing it's thing, and advancing/retarding spark properly. I also wondered if someone tried to tune the ECU.
