I put together a inner clutch cover with clutch housing to carry on the road with me. My question is: Has anybody found any difference between a 650 H1, or 700 H1 inner clutch cover? I've looked up different years of the 650 & 700 and they carry different part numbers, but the gaskets line up on the bolt holes, bearing size is the same, seal is the same, and so on. I put them side by side and I cannot find any difference! Any thoughts?
