my 03 883r sportser has sat since nov and took it out other day and its fine untill warmed up then it starts puking oil out all over from between the battery and oil tank which looks like it maybe is coming from the primary over flow vent? not sure what would be causing this and what do i need to do. any helpful advice would be great thanks.

 

did you add oil to engine?
maybe it drained down to bottom of engine and thought it was low and added oil.
my brothers old FLT did this but puked it out the air cleaner what a mess

 

yes i added oil. today i changed oil, checked oil lines nothing plugged. put new oil filter on. cleaned air filter. started it up let idle for 15 min or so then took it for a ride. it does not do it until the oil temp is between 100-140 then itll do it. ive never had an oil leak issue and ive owned bike for 3 years. its not a few drips either its alot of oil.
