07 Ninja 500 coolant leak
Cant seem to upload a photo so it is attached at this address: https://m.imgur.com/a/my2lC1k
Basically I bought this bike 3 weeks with them telling me everything is working perfectly but the bike did sit for a year. I noticed this passed weekend that there was a small leak because of the smell, can anyone tell me what this bolt is and what might cause this? It is to the left of the coolant drain plug. Thanks in advance!
