My bike is slowly killing the battery like over the course of a month or 2. not sure why cant seem to find a drain? any ideas?

 

What happens? New batteries dying every 2 months or so?

 

Yeah most likely your R/R is toast and is boiling off the battery ! ...... making it toasted !

 

That's it dyig every 2 months.

 

99.9999% probability that it is your regulator/rectifier. I'd start by replacing it.

There may be a good way to test for sure if that is the problem but I don't know it. I am not good with electronics. I really don't think there is anything on an F2 that can drain your battery though that isn't obvious (like lights being on)
