 Product Description

                                                 ***** PLEASE READ TERMS AND CONDITIONS BELOW CAREFULLY *****

                                                                               **Long Live the 1200!**

This auction is for a CUSTOM ROSS RACING XJR 1250cc (manufacturer advertised 12.5 / 1 COMPRESSION with full dome) Piston Kit as shown in pictures 1 thru 6. Pictures 6 thru 12 are so my on-line customers can feel secure that they will be dealing with a company located in a brick and mortar location that has the equipment, personal and inventory to give our customers the service they both deserve and need.

When used with a FJ1100 it is recommended to use a FJ1200 or XJR1250 (1300) cylinder block with big bore sleeves (YA-991) or larger. If crankcase cleanup is required and Andrews Motorsports can perform the machine work if needed. When used in a FJ1100, FJ1200 or European XJR1200 series engine big bore sleeves are required along with crankcase cleanup. The last application series engines (1250, 1300) does not need crankcase cleanup if sleeved, as there is enough room for the cylinder sleeves to clear on assembly, if using steel sleeves. Piston kit can be used with the "chrome bore" XJR1250 (1300) European series cylinder block.

This kit includes: (4) Ross 79.00mm 3.108 +/- pistons, (4) Ross R3113 79mm ring sets, (4) wrist pins, and (8) pin c-clips 4000 WA-9, head & base gaskets available seperately. This kit is a 1250cc and the advertised piston size is (3.108 / 78.94mm), (3.111 / 79.02mm finish bore size). Due to temperature variations and production runs or the human factor piston size can vary + / - .0005.

If you need any machine work done to your block, we also specialize in that service. Please call the shop at 704-782-6134 8am / 5pm Monday through Friday if you have any questions about machine work for the piston kit. Andrews Motorsports can provide all necessary mechanical and machine work if needed.

The crankcase does require boring (cylinder sleeve clearance) for the install of this big bore kit in the FJ1100 or FJ1200 series engine crankcases.
