Deciding not to alter things to much, I cut off the folded edge of the foot plate and that has give 3/8" to 1/2" of clearance for the tyre. Next, out with the jigsaw and I opened up the hole for the fuel tank filler cap .
Put everything back together and time for a photo shoot.
And a comparison photo.
By 'eck! Wasn't expecting that much difference. 3-1/4" difference.
That throws up another problem. Getting enough ploughing depth. Maximum I will be able to get is just over 4" deep. Could be another addition to the Black Horse topic.
