Tony, realistically, not much longer at all. The adjustable side was fine, it was only the non adjustable side that was a bit tight. Had i not cable tied it to the tie rod it wouldn't of been an issue but i didn't want the cable flapping around fouling the tyre and/or tank, and i see you too decided to cable tie it to the tie rod.

I would say literally an inch longer, 2 inches max. and it would be PERFECT for the job
