We found no metal in the oil.

New pistons and cylinders are likely going on today.

Should this engine be flushed in some way before installing them? After? If so, is there a procedure for doing so?

As always, thanks in advance for your input.

 

There is a product called flushing oil, however that relies on running the engine, to flush it through the system. I'm not sure if that is appropriate here, having read your other thread. Certainly a new oil filter and fresh oil, as a minimum. Your builder should know his stuff and do the right thing this time!

 

 

ide be more concerned on why it happen in the first place

 

Prodrag, I posted this before visiting my builder to have a better understanding of the process so I could speak with him from at least a moderately informed position.

The buklder is going to pull and clean the pan, and seems just as committed to not seeing this bike any time soon as I am and assured me before I really mentioned the issue that this bike is not leaving his shop until whatever might be in the crankcase / oiling system is gone.

thanks for your tip about the flushing oil. I'll talk to him about it and suggest that he use it if appropriate.

 

That's a great question. Like many failures, I think this one had more than one cause, but I'll never know with certainty. All I can do is try to keep the factors I think may have contributed to this from happening again.

Once everything is resolved, the bike is running well, and I have all the info I need to do so (still need to upload the fuel map from my PCIii), then I'll post a sort of After-Action Review of what I think went wrong and how it might be prevented in the future.

 

really only 4 things it can be,all pretty easy to find.either set too tight,lack of oil,too much timing or too lean.make sure to check the piston jets if everything else checks out good

 

I was wondering about piston Jets myself. I put s&s piston oilers in mine.

 

Hi I was wondering if you ever came to any conclusions and posted? Thanks

 

S & S provided new pistons and cylinders for free which gives some validity to the idea that they were defective somehow.

​​​​​​Mechanic made sure oil pan was clear but I don't think he actually flushed.

Broke in new set very deliberately and now have about 15k miles on the build.
