I dropped by bike and after that is started to run rough - so i took off carbs and cleaned them out - put back together - and it wont start- there is petrol on spark plugs and good spark on all 4 plugs.When you spin it trying to start it - all the engine oil disappears and it back fires and smokes - but will not even show a hint of starting or taking?when you leave it - the oil returns to normal on dipstick?
