Piston Liner Set 1750 81mm 10.5:1 1750 1mm Overbore Kit 1779-1824cc APPLE BITE DISH DOME
[PL81-10.5]
$1,147.00

Sorry, but temporarily we can only provide oversize piston/libne sets with our engine kits.  The accuracy of both new and rebored liners is abysmal.  Only one source can hold tolerance and they cannot keep up with current demand.

6 HORSE POWER GAIN!

This 1mm oversize bore kit increases displacement (45cc) from 1779cc to 1824cc. This 2.5% increase in cylinder volume makes about 4 HP. The increase in compression to 10.5:1 adds about another 5 HP, bringing the total gain to an estimated 14 HP. This extra compression makes a huge difference in performance off the corners. 

CUSTOMER COMMENT:

I am working on my rebuild and admiring the quality of your overhaul kit.  The JE pistons are absolutely beautiful and I'd like to share the specs were spot on.  I couldn't measure any variation between them and they fit the liners perfectly to spec.  The liners were very true with .0003 being the largest variation I could find.  So happy for this.  EE in USA

LINERS:

These liners are rebored from good core 80mm 1750 liners. They are true to .001" for taper and out of round. They are fitted to our 81 mm pistons at .003" to .0035"

  • Our rebored liners are sold on an EXCHANGE basis.  However, you must send your core liners in advance of shipment.  Sorry, but we have to do this because 90% of customers never return cores.
  • NEW LINERS are available.  Add $350.  No exchange necessary.
