2021 KTM 790 Adventure R Fuel system Problems

“When I start the bike, it sounds like the engine is only running on one cylinder and misfiring. It runs 'rough' like this for about 30 -60 seconds and the revs are sitting between 1000-1300 instead of the normal 1300-1500rpm range. You can smell fuel while this is happening. It then 'pops' and the engine runs fine after that. I live in the Netherlands, but wanted to register the issue here as well for investigation.”

“When engin is cold for more then 8 hours. Engin will start only on 1 cylinder (right), for +/- 1 minute (1000 +/- rpm), after, you will heard internal explosion, and left cylinder will start (1600 +/- rpm) . and dropping at 1400 for normal idle. With an strong gazoline smells after start-up, after 2 3 minutes smeel is gone Please note that I live in Canada Quebec”

“The motorcycle is having a cold start issue. When starting after 24hours, the motorcycle will not start right away or will only start on one of two cylinders. After roughly 60 seconds the second cylinder starts up.”

“Motorcycle hard/impossible to start. Excessive valve wear. Currently unrideable due to mechanical problems. Motorcycle stalled at intersection of busy highway, would not start creating hazard of being hit in the intersection and while pushing it to side of road. Mechanic inspected vehicle, found excessive wear to valvetrain causing engine power loss and stalls. States that it appears to be a manufacturing defect in the intake system allowing dirt ingestion leading to excessive irreparable valve wear.”

“Motorcycle does not start properly when cold. Takes several tries to start. Once started it dies several times and must be restarted. Once running, it idles very rough for several minutes.”
