Selling my spare 1989 top end
It is stock bore 66.00mm
I was running it with a 86 cr250r style wiesco piston on a 86 bottom end
so I was not using a spacer plate.
If you ran this set up with the piston I have on a long rod motor it would require a spacer plate.
It has the port castings cleaned up but nothing done to the port timing
piston/rings have about 15-20 hrs use on them used but still look almost new.
I had it boxed up as a spare incase any of my 310,s ever craped out but never had any problems so its just taking up space Ill get some pics up soon ran great when removed
1989 cylinder & head never bored, clean up ported
1986 style wiesco piston kit (used) 15-20 hrs
$250 shipped any where in the lower 48
