Good stuff Matt. Like I say mate, my bike ran totally fine with it as it was, so personally I'd just give it a good external clean with said toothbrush and solvol. Bolt it on and try it first. Hopefully won't need to strip it down. As someone on here has as their strap line "if it ain't broke, don't fix it" wise words I'd say.... best of luck with it. Keep us posted🤞👍.. cheers, Michael
