The day before yesterday when I came back with my tw I had an engine power problem with a glig glig noise 5 km from my house I managed to get home on 1 cylinder, I removed the rocker arm cover and found that a cup that retains the valve spring is pitted from the center, luck or not S&S sent me an email on 09/12/2022 to tell me that 132cub pistons were available ( https://www.sscycle.com//products/ forged-piston-sets-for-x-wedge-engines-standard-132-inch/ ) I myself already have new valves in stock.

the problem is that I contacted my S&S supplier with the email to order me the parts as well as a pair of 121cub cylinders which was available on the internet, for a while my supplier never got an answer, was a bit disappointing on their side.
the x-wedge quality does not surprise me when I see camshafts damaged by the needle bearings at 5000km and that others are more than 50,000 km before being worn out there is a problem with heat treatment or precision of machining.
