smells like gas in my oil after the crash. the bike was on it's side for only about 10 secs but the marks on it would indicate it was actually upside down at one point. 1. is this normal? 2. should i run some new oil and re-drain to make sure it's all out? i also have some seafoam lyin; around if it'll help. 3. would i need to top off the oil if it's just a "cleaning cycle"?, or would a liter or so be fine? and 4. would this be the cause of an engine light? thanks for the help!
