I have to rebuild my 110 and I wonder what engine to go for.
Long story made short: 3500mi after my dealer changed cams, tappets, oil pump, pushrods, and one valve because of a bad noise, the rear cylinder seized. He didn't want to repair under warranty and after a long conflict, I had to get back my bike, after paying disassembly and a lot of caretaking costs...
So the rear piston scored badly, piston skirt is damaged, rings are welded, lower end of cylinder is scored and with a thin crack.
As the engine was still running, I believe the crankshaft didn't suffered, and would perfer not to change it...
My plan is, for now, to replace cylinders, pistons and cams.
I could go for another 110 either by SE or an aftermarket provider, but I could take advantage of this situation to begin a cool upgrade, to 113 or 117 (or 124?)
I have seen several possibilities and would like an advice:
- SE 117 kit (92500051): drop in, no modification (case boring)
- S&S 117 (910-0474): .060 shorter cylinder: have to modify TB ?
- Zippers 1117 (520-417S): .045 longer cylinder: have to change TB?
- Revolution performance 117 (DragSpe 0903-0897)
- Suburban Harley solution 4-1/8 SE cylinder + Mahle pistons
- Fuel Moto 113 kit for CVO (FMS-11-X): with cams, lifters, pushrods, bearings!
Of course if I need to change the crankshaft, I could stay with a 4-3/8 (S&S, Darkhorse, SE) or go to a 4-5/8 and build a 124... But is it rational on a CVO Softail Deluxe?
