Well... my saga with issues continue.
TLDR: supposedly my top piston has no compression, no CEL, but have received P0172 and P0175 (rich banks) codes. Ducati wants to deny me warranty because of mods. Looking for guidance on how to approach this issue, as my mods are pretty standard and the ECU flash is nothing more than fueling adjustment to keep things smooth.

Extending from my other thread, I was having issues with the Rexxer tune, but seemingly worked it out w/ Rexxer. Took the bike on a trip up to Bend, OR from San Francisco, and started having issues. Local Ducati dealer picked up the bike a couple weeks ago to inspect it, and they say the top cylinder has no compression. I could use some guidance, as the dealer wants to deny me warranty because of my mods, which consists of -

Local Ducati dealer picked up the bike a couple weeks ago to inspect it, and they say the top cylinder has no compression. I could use some guidance, as the dealer wants to deny me warranty because of my mods, which consists of -
- Rexxer ECU tune
- Comp Werkes exhaust
- MWR PUK
- EVAP can removed
- After getting the Rexxer tune situated, the bike was running super smooth and strong
- The day of departure, was on a 6 hour ride out past Sacramento, where it was pretty hot 95F+ degrees or so, but nothing crazy for the area, and was moving in traffic at 80 mph
- Got to a gas station to fill up, started the bike and it started funny... like a very very weak/wimpy start
- Thought nothing of it, and rode up a 5 mile hill climb... while going up the hill felt the bike being sluggish, but I figured it was cause we were at elevation (like 2.5k feet) combined with hot air temps
- Got to the top of the hill and felt the bike bogging / choking and wanted to cut out... so i pulled off onto the shoulder, and the bike shutdown on its own. Noticed oil smoke coming out of the intake - I have the MWR PUK
- Tore down the air box, didn’t see any oil inside, but smelled oil fumes... oil looked ok through the window, good on level, no foaming
- Camped there overnight since the sun was setting and in the early morning, I went to the nearest auto store and did an emergency oil change, inspected the plugs, etc... nothing seems weird, but the bike felt weak on startup... Oil levels were all good - it fired up no issues, but also the engine was already hot
- A couple hours later, bike started to feel down on power again. Checked ECU getting P0172 and P0175 codes, which are “running rich” codes on each bank... (No CEL)
- Reset ECU, bike felt strong for a while... but again, later in the day, started to act up, and it wanted to cut out... being boggy
- Made it to Bend... reset the ECU in the morning, felt pretty good, but by the end of the day, same codes (no CEL)
- Rested the next day, cleaned the air intake an MAP just in case something was clogged up
- Bike was acting weird on startup, but after clearing codes and resetting ECU, it fired right up (no CEL)
- Fourth day went for a ride, intermittent issues but did mostly well... much cooler temps
- Heading home, from Bend, bike tended to bog in hot weather... was getting the same codes... at this point, I figured it was probably the PCV valve that was blown out
- Stopped at a gas station, and noticed oil coming out of the breather hose, and coated my under tail and left side of my tire.. sketchy AF (still no CEL and no dash warnings)
- Made it home, limp mode, trying not do any kind of leaning on the left
- Shut the bike down, didn’t start it up or ride It again
- Scheduled my shop to pick up the bike (tow service), it started up really rough...
- They called me today and told me my top cylinder has lost compression... and that a rebuild would not be covered under warranty
