I have had water in the cab a few times in the past, cleared drains ect but always had trouble finding Botang's. I've had the ecu's out but could never get the box out. Anyhoo i've had a go this wk-end and think i've found it, but still not 100%
Now i know that 1 is left and the other right hand drive but, This is from Notorious and the hole is just a hole.
This is from Davisbike and is a captive thread, the same as i found.
So off i went to my shed to see what i could find. Tapped hole is an M6 so a stainless bolt, washer x2 and some single sided foam tape.
But in the end i dropped the plastic washer for a larger stainless to spread more weight over the foam
The foam is water tight at 3/4 compression so i just done it up handtight with a socket, extention and wobbler.
