Lee, won't your IST ignition do something when it picks up with the knock sensors and all the other junk on it?
They make another setup that will adjust for lots of conditions on its own. Its called EFI.

Unless you get a self tuning EFI it won't help.
Standard EFI has the same issues. And it is only as good as the tune that is put into it. My bike just ate another set of rings. We found out that the dyno tune looked good until the oil got hot (above 230 degrees) then the bike went lean. The tech that dyno'd my bike is good. I don't think anybody could have found this combination for the perfect storm unless they tuned each cell. Then it would be wrong when the weather changed. Of course this happened right in the middle of where I cruise. And I spend hours on the bike at this point when I go travelling. So with only 1200 mile since the last rebuild they are rebuilding it again. This time with a thundermax controller instead of the race tuner/delphi ECM combo. I hope the 4th time is the charm.  These issues are why I started coming here. To see if 117" engines were just cursed. I found out, it was just mine.

Thanks Hoat I will check them out. That would help A LOT. I know when I leave here it doesnt matter until you change 2500 feet but thats easy to do with the great mountain range here and then home to South Dakota is at 1300

D,
From what I can see in the pics. the wrist pin looks just a little scared (scratches), most likely from the piston heat transferring into the rod and affecting the lubrication abilities. Just keep in mind when doing anything, like Vegas remarked, higher altitudes = less air, and less air = burning rich (fat). The reverse is as well true, lower altitudes = more air, and more air = burning (Lean)! The piston in the pics. doesn't look too bad, as far as burning mix. But remember, this is "not" a race engine, you don't want it to burn too awfully hot & clean. Personally I would like to see mine looking a little darker (Richer/Fatter). Bikes like to be a little (fat). (Fat) = added torque! And that's what you "feel" in the performance of the bike. HP is great, but you can only really feel it in the higher RPM ranges and only then "if one really know what you're feeling and looking for"!. But, if you don't have the proper combination of HP along with torque, you really won't have much. So in reality bikes that are tuned to run just a little richer, run just a little quicker (torque) and better. Just to give you an idea in differences. When I was racing, we'd go to the east coast at one race. Lots of humidity= less air, OK, so we'd (Lean) it down some, right. Then we'd leave an go to Phoenix, Hot & Dry = more air, So we'd (Fatten) it up some, right. You wouldn't think that there's a tremendous amount in the altitude differences between High Point NC. (Elev. 1,007 Ft.) and Phoenix AZ. (Elev. 1,117 Ft.) Some yes, but not a lot. We'd have to richen up 2 (main) jet sizes, or we'd loose pistons after 1 run! So the air densidy plays a factor as well. Start being a little rich (Fat) to be safe! Then adjust the ratio. Just my thoughts here. Good Luck!

Dakotabos. Click on this site go to pic 1 here are the oilers Im talking about does your engine have these spray jets? Getting the bike back together is top priority at this point! The pictures of your piston show me that the rings are carbon up and stuck. So i think this has been going on for some time.I can see carbon scoring on the liner and glaze. Correct me if wrong I also see the piston separated on the intake side.I still think you have a defective cast piston or the valve smacked the piston which I cant see if it did though causing that fracture. Hope all goes well on your rebuild 05chop in southern wyoming http://www.zodiac.nl/instructions/S&SSSW+Engine.pdf

I will check that out tonight when I swing by to clean up the Gaskets. Thats some great info. I am working with S&S and Big Dog to see what they think. S&S even sent me my sheet for my engine. That was great of them. Shows all part # and size

Dead one It sucks when your bike is down I think any good input will help.Finding the cause of death has been a learning experience for me. Maybe AL or Marv should jump in.

(RE-EDIT)
Gentlemen and Brothers, After re-reading the previous postings, I see that I most likely "misinterpreting" the postings. Evidently I have the same material inside of my head, as the outside of my avatars head! "NOTHING"!  But no excuses here, I have none. I "Fd-Up", and I would like to offer my sincerest apologies to "all" the persons posting replies, site members and outside viewers as well. I'm very sorry and It won't happen again! And "IF NOT" misinterpreted, "Screw It" I'll re-post it later!  TheDeadOne or just "STUPID"!

???? Whats up DeadOne it looks to me like you know what you're talking about and I'm sure your input is hugely valued here.
Yeah Gas you are right about the S&S IST ignition, good thinking - Dakota, might be something for you to think about. It has heat sensors and knock sensors and will automatically adjust the timing. Me and HDLarry are running this system and it works great. Its pricey though and takes up a lot of room. I did a how to on the install if you want to check it out.
