Thanks for the advice guys. The rear does ride low with me on it. When I strip it I will get the shock off and measure the length, perhaps it is not correct. It has a white spring that makes me suspicious. The rear tyre is a 70 profile and needs swapping out. The track day was all a bit rushed and I wanted to give the old girl a run out before the end of the riding season. Now it is rebuild time.

What rear shock would people recommend? Is the standard Honda unit rebuildable? What tyres would suit this bike best? I had planned on BT090, but BT003 seem like a reasonable choice.

Thanks again. It's great to get people input, so I don't miss anything when it's in bits
