Dont know about the clutch issues in a d22, I think there were clutch issues in the earlier d40s but if you do a search you might find something. Power... well... limited. But you can Chip and exhaust and get some good returns. The power doesnt bother me, but if you want a race car this aint it. I am setting mine up as off road/tourer and am really happy with it. I think for the money you pay, you get great value. (check the thread on buying new you will see what people have paid.)
