Yep!! Way broken! From what I have heard, the pistons used on the Saxon 980 kit were not known for their durability. It's my understanding that all of the kits that have been installed will come loose sooner or later.
I purchased the bike with the kit already installed. Right up until the time it let go, the bike ran VERY strong! I could keep up with the newer Daytonas. I couldn't pull away, but I could keep up and hold on.
On the way to Mid-Ohio for the Superbike races this happend.
After I took the engine apart, I looked at the other two pistons to find that they were cracked as well.
The picture shows the remaining pieces of the piston at the bottom of the case.
