2019 grom.. So the bike was stolen and when it was recovered 9 months later it looked as if it sat for 8 months. I changed the oil fixed / replaced everything damaged and it ran decent. I thought it was okay and when I took it to wintervacation it died out five min after riding. nowww it won’t really stay on. It’s running very lean and when the bike turns on it idles very inconsistent and when I try to apply throttle it dies immediately. If I just turn the bike on it just idles for 15 seconds then dies. I’ve checked the spark plug, the valves, the gas, the oil, air filter, swapped throttle body.. I’m lost and need help.
