I stuffed up the part number when ordering the grey, right hand engine cover on my 2000 manufactured ex-Police ST1100. I got the smaller engine cover for the civvie ST1100 (I think its for later models, from 1995 on). The part number is 64260-MAJ-GooZA, coloured grey (colour NH-285).
So it's free to any other ST1100 owner out there who's prepared to arrange pickup or freight/postage from Mackay QLD. I am prepared to ride a couple of hundred km to pass it on to someone, say Bowen, Moranbah, Marlborough (half way from Mackay to Rocky). That'd make it a good days ride for me, there and back.
