Ok so I have kind of a weird one for you guys. I have a 1963 Chevrolet Corvair that I have swapped a 2012 1199 Panigale v-twin into. I bought the engine and some parts off of Ebay and then pieced together everything else from the Ducati parts catalog (not fun $$$).
The project is almost done, and I have had the motor running perfectly for a couple months now but I want to run through some of the initial problems I was having because the same thing has just started happening again.
When I first fired up the “bike” it ran unbelievably rich, as if all the injectors were stuck open. I then pulled the exhaust off and it would idle barely. I ended up getting MelcoDiag and resetting the tps and fly by wire throttle, this fixed everything. I have a youtube video of it running and it's flawless, as it should be.
Fast forward to yesterday, and I tried to start it but unintentionally had the throttle unplugged. The servo motor for the throttle bodies opened and closed when I tried to start it and I quickly realized my mistake and plugged it all back in and tried to start it, and once again there was raw gas coming out of the exhaust. That's how rich it was. Both plugs were fouled and I ended up breaking one taking it out (I’m an .....) so sadly I have to wait a few days to get more, but I did the resets on MelcoDiag and it seems like the overfueling has stopped from what I can tell.
Unplugging the throttle is the only thing I can think of changing that would have caused this but I don’t understand why. Does the TPS have to be reset when you change your handlebar throttle?
I know this is way out there but I’m just looking for insight as to what could be causing such harsh overfueling? Both top injectors looked like fire hydrants when it was running without the exhaust on lol.
I am thinking a tuneboy would be beneficial, although I am not sure I could ever get this thing on a dyno.
The full forum post is over on the corvair forum if you are interested, but that is unrelated to Ducati motorcycles partially so who knows.
Thanks for your time,

Here’s a video of it running during the time all was well :
And I've also attached some photos.
