£5500

I have a set of brand new Superior cylinders which have been ported/polished and heads alodined by Lycon.

Lycon charge $385 per cylinder for this work, plus my shipping costs (£400 each way). In addition to the porting and polishing, all four cylinders are flow matched resulting in a very smooth running engine. They also do a multi angle valve seat cut and gap the piston rings for you.

These cylinders are currently £1650 each, plus the work by Lycon. They do not include the rocker shaft or rocker boxes, but the cylinder assemblies are complete and include the (already installed) rings and pistons.

I am no longer using these cylinders as I ended up using Lycoming cylinders instead.

They are supplied with a "repaired" 8130-3 however they are brand new and unrun.
