2021 S2S motor blew up!

[ARtraveler]

We do hope that Joel will come back and fill us in with the details.

I am speculating that the trip is to test out the repair(s) that were made. If the repaired engine does not make the trip, we should be able to hear Joel from wherever he is.

Joel, hopefully no more issues with your S2S. Seems this Spyder versus your previous Spyder has tested your patience between the electrical issue and this engine issue. Seems time to enjoy it fully, if your confidence has been restored.

We do hope that Joel will come back and fill us in with the details.

By Joels words, another tech apparently mentioned the stuck or carboned valves on another Spyder, plus a computer mapping change, so very likely this has possibly made it to service bulletin status, alerting dealer techs of the issue.

Hopefully the issue is few and far between, not leaving owners stranded, similar to the older DESS issues.

250 miles on the S2S today and a trip to Mount Equinox in Vermont. It ran excellent!! I would almost say the best it ever has. I did change the oil at 6am this morning before the trip. Hopefully all issues with this expensive toy have been resolved. I dont need anymore stress.

Joel, would you mind telling us what the techs found wrong and fixed? Thank you.

[Joel The Biker]

They found carbon on the valves causing no compression. 2 cylingers had zero compression and one had 30 lbs. They cleaned the carbon and now all three are nearly 200 lbs.

Thanks. Did they have to remove the heads for that?

Did they say what caused the carbon buildup and how to prevent it happening again?

Incidentally, I once owned a 1985 BMW 318i on which they had a recall to clean the valve ports by blasting the head with walnut shells. Interesting.

No engine disassembly like I said previously. I was extremely happy about that. The fix was simple. I will let you all theorize about the cause. I have my theory. LOL. And I have heard the mechanics theory. And I have heard from a previous tech and his theory. LOL If it acts up again, then my theory is wrong. I accidently stumbled on my theory after talking to a coworker. Needless to say, I have more questions for him. I am just glad my S2S is fixed without major surgery. That will help me to trust the machine again. I want a spyder I can ride for the next 10 years. My 2014 was extremely dependable and that is what I expect from the S2S. Im signing out on this thread! Thanks to those who provided positive ideas and encouragement. Very much appreciated!!!

They said they cleaned the carbon. How? Removed the head? I want more answers. Mike, how is it an easy fix? The bike would not start, so you cant seafoam it. I dont believe in seafoam anyway. No fuel additive is going to instantly clean valves. Carbon build up in less than 7000 miles? No way. This spyder will be sold. I am not going to be left stranded somewhere.

Thanks for answering Your Question ..... ie. the fix was " simple " no engine dis-assembly ie. head re-moval ....Happy you got it fixed ..... Mike

[tomknotts]

Man i hope it work out for you. With my air bag issue and other stuff i have read about the s2s getting a little nervous about my investment. Fingers crossed it is fixed. If your theory proves out right and it doesnt come back can you let us know please. I wanna make sure it doenst happen to me.

Thanks for the grand finally and the little secret at the end!!! We love the suspense!! Good Luck!!!

Joel, glad to hear you're back on the road with s2s. Hope there are no more issues for you.

[Bangorbob]

I guess I missed the FIX. Please educate me. Thanks.

For sure but somehow removed carbon from valves without major disassembly as I understand it. Winner is it is FIXED & not 4sale

[UtahPete]

"carbon build-up " ....if that's true ( NOT ) then it's an easy fix and you have the bike next week .... good luck .... Mike

I think you probably nailed it Mike.

[PMK]

By now, the title of the topic is very misleading and demeaning to other owners.
It is apparent the engine did not blow up. Merely seems to have suffered from old school 1950s era carbon buildup that rendered two cylinders with no compression and the other at 30 psi. Odd though, to accomplish a compression check, they must have at least gained enough access to remove all the spark plugs. Probably a shot of WD fixed her right up...

Time to close it down. Gone South to far.
