Had a little time today to run the jugs over to the machine shop to have them professionally honed while I wait on an order from UL Power to arrive of new piston rings and a few other goodies. The worst cylinder was shown to the machinest and he claims the hone will save the cylinder from the dumpster, but I thinks it's a close call. Should have them done on Monday. In the meantime I pulled 1 of the pistons and brought it home for a chemical bath in the NASTY Chem-Dip by Berryman. Open windows and gloves are required while soaking. Unfortunatley I'll have to post results tomorrow after it's been able to soak for 4 hours. Hoping to see shiny clean pistons ready for new rings and freshly honed cylinders.
