2 weeks ago i highsided and the bike ended up.on its side still running. I should have check the air box for oil immediatly but.i didnt. A day later bike would die when idling. I opened the airbox to find a puddle of oil. I cleaned box, changed air filter and sparks plugs which were black and smelled like gas. Now the bike backfires and pops on idle and decel. Otherwise it runs great. I was thinking of replacing the.wires. any advice? Maybe carbs got clogged? Thanks in advance.
