Just trying to find a slight pesky coolant leak on my 45 , and it seems to be coming from the top rad house . Anyway , I was trying to see where the hose goes into the head , so I took the tank off and found this on the airbox lid ,
So it's just a hole , which I presume a previous owner had done to aid/increase air flow ? . Can anyone let me know what's supposed to be there ?
Please note the use of the HRC approved mallet to hold the tank open.
Thanks
Mike
