This is a pair of modified 88mm "1000cc" big bore piston and cylinder sets for 850cc round head engines. These piston and cylinder sets were originally manufactured to be a replacement for V1000 Convert, SP1000, V1000G5 but has been professionally modified by reducing the cylinder sleeves outer diameter so that it fits into the engine case of an 850T, 850T3, or Eldorado.

This item includes 2 new cylinders with Gilnisil plated bore, 2 new cast pistons, 2 sets of piston rings, 2 wrist pins, and 4 wrist pin circlips. One set is shown in each photo, but two "sets" are included in this sale.

Notes: Rebalancing of the crankshaft for the larger piston is recommended, or alternately, you can swap in the crankshaft from a 1000cc model. To use these in Eldorado requires some minor material removal in the push rod tunnel, or updating to the angle rocker arms of the 850T and later models. 

Gilardoni piston and cylinder sets are without a doubt the best solution to worn, blistered or peeled chrome bores as well as worn or damaged iron cylinder bores. To be cost effective, lesser repair methods (such as boring the old cylinders and installing iron sleeves, or re-plating the old cylinder bores) often re-use the old pistons which typically have suffered wear. Installing sleeves or re-plating used cylinders, and then buying new pistons (if available), piston rings, wrist pins, circlips, etc. can easily meet or exceed the cost of these Gilardoni sets. Sadly, we've sold many of these sets to people that have already spent money on the lesser fixes, only to have to do the job again with the right stuff. Gilardoni is the original equipment manufacturer for several new vehicle manufacturers, and their products have a very good record for performance and longevity.
