Hi
Any ideas what might be causing these bubbles?
The bike has been in my shed which gets very hot (Qld summer westerly facing type hot ie very hot) for last 2 weeks whilst I await major service kits to come from England. And today I noticed these bubbles had appeared which presumably are along the weld lines of the tank.
They're not solid ie like rust but soft so my first thought was it must be the gas fumes expanding (only 5/6L in the tank atm) and the pressure vent must be blocked, but when I opened the petrol cap there didn't seem to be any pressure build up, well not that i could notice. I do intend on taking the tank off so I can check vent line when I deoxit electrical connections, but wondered if anyone has an ideas or seen this before?
I have left the petrol cap slightly ajar atm to see if they go down of their own accord. Not willing to pin prick them atm.
Thanks
