I have a 2022 Vertigo Nitro Jaime Busto Replica 300 that runs very rough past 1/4 throttle. First 1/4 is pretty good, idle is fine. Did it pretty much from new, bike now has 30 hours on it, and it seems to be getting worse. Past 1/4 throttle it runs very rough, repeated surging and near stalling, but only under light load. Hard acceleration is good, steep uphill is good, 5th gear on flats or slightly downhill is terrible, to the point where it nearly stalls. There's also a spot about 5000 RPM where it just doesn't run cleanly at all, lots of smoke and very rough. This bike has the lithium battery with a different wiring harness from earlier models and a 6 pin plug. I bought a wificom but can't connect it, the wificom has an 8 pin plug. My JBR's 6 pin red plug looks very much like the iso 19689 connector. The dealer has said it's not though, and doesn't have a Vertigo diagnostic box and software, on backorder. Does anyone know if that is correct and it's not the ISO standard, or it is and I can get an adapter from Amazon hook up an OBD2 device to this bike to help diagnose the problem? First plug replaced at 8 hours was black and wet, 2nd plug at 20 hours was better, very light tan, but I am getting quite a bit of soot in the exhaust. I haven't pulled the third plug yet. I have pulled the intake/pump/filter/pressure regulator assy, no obvious defects or splits. I'll have an actual pressure reading this weekend. The air hole in the gas cap is not plugged. I haven't tried replacing the TPS because with no way to zero it I figure if it doesn't solve the problem I now have two problems. Dealer is 6 hours away one-way, so it's a full day/$200 gas to drop it off and a full day/$200 gas to pick it up so I'm more inclined to try to diagnose it myself until at least one of us has a programmer. It also had a problem with the breather box not sealed from new, leading to transmission oil in the airbox, so I originally thought it sucked in some trans oil, which is why I say "pretty much from new", not sure if the trans oil caused problems from the start or in fact were any part of the problem. Fuel ratio is 130:1. Any suggestions?
