I must admit I took my side cover styling que's from the pics published of the white Tenere with the Acro pipe.
This is a temporary measure for me until I complete my pillion peg hangers that will incorporate pipe guarding.
I simply marked the side cover on the bike with some pin striping, then removed it and cut it on my bandsaw.
I cleaned the edges first with a file, then with a ruler (or similar) sharp edge.
Prior to cleaning the edges I cut the inner heatproofing with a scalpel and peeled it off.
I then marked the centre cutout and drilled the perimeter before cutting between the holes with wizzsnips.
I then cleaned the inside line with the dremel + files + sharp edge.
Not sure if I will paint it as I dont plan on leaving it on for long. >
It's easy and cheep to do so dont be shy folks.
Greg.
