that's a tacho, you daft bugger

I paid £15 for mine

and its a xs 650 rev counter 7500 red line, they cannot even get the part number right

well spotted Merv, never looked that close!

If you look at the pic it has the XS650 1J7 part no on the box , and that is a big dealer, i bought summat of em recently I dont remember who it was now but it is a big dealer possibly Len Manchester
