I installed and ran the Parmakit about 700km ago and just recently the engine siezed. I pulled the kit apart and surprisingly, the piston shattered in three places. I was only running around 45-50m/h when this happened. I was NOT full throttle and I had plenty of oil in the tank as well as the injector. What would cause this to happen? Is the Parmakit a mediocre upgrade?
