Sigh, I knew not to hit the button. Brad, usual"¦Thank you for contributing nothing less than nothing. I am now stupider for even thinking of reading what might lay beyond the "View post" button"¦.Well,,, on the bright side it wasn't "See, exactly Ducati still sucks, and it breaks, and its too expensive, and why would you buy that, and I love my HP4, and, and, and, and"
NOLA.
NOLA,
Judging by your response.
I honestly think you've got me confused with somebody else
I put it to you that your distorted personal views of me are sadly starting to cloud your better judgement.
I submitted sound advise, and you seem to be focused on criticising my input.
Further, if it was my machine and I was so worried about the sparks coming out of it while it's on the dyno.
Then I would take the exact same course of action that I outlined in my previous post.
Especially given the evidence at hand, about the apparent physical condition of the engine, with no other reason "what so ever" that there is a fault with or defect with it. And I was persisting with the premise that something must be wrong.
Everything else really is pure speculation unless you get inside the engine for a visual inspection.
Seeing as you lack the fundamental reasoning as to where to start on the matter, and get to the bottom of it.
Here's a tip for you as a place to start looking.
Step 1.
Failing any conclusive results of a cylinder leak-down test on both cylinders.(with the pistons at the top of the compression stroke).
Step 2.
Pull the plugs, and put a Borescope down the holes to have an initial look for clues. (with the pistons at the bottom of any stroke you please)
Step 3.
If that still doesn't satisfy your inane curiosity.
Then pull literally the heads off.
It's really as simple as that, and cheap insurance.
Seeing as you are reluctant to accept the prima facie evidence at hand regarding the engines condition, and the reasonable explanation of the loosened carbon from the top of the piston or squish area being spat out of the exhaust.
If you want to play.
Then start to pay.
Good luck with your quest
I hope it goes well for you
