You already know what convinced me Dreth, but many others don't. I'm trying to let them know about the upgrade at a VERY reasonable price. In terms of the life of your motor, this is the best money that you can buy. I've never had problems with my bike but I wasn't going to take ANY chances. These pics are from a friend of mines bike after ONLY 3 HOURS on the motor. Due to lack of oil on his wristpen and rod, THEY BOTH SNAPPED! His wristpen seized to his rod and the only way I could get it to rotate once I tore the motor down was with a pair of pliers. I shipped my parts off to have this mod done a couple weeks later
.
Crack in engine case from the rod being a weapon against itself...
Indentions were valves slapped the piston when rod and pen snapped...
2 Cracks in brand new cylinder...
Piston and inside of cylinder...
Rod and wrist pen snapped/ piece of nicasil broken by piston...
If you look close enough, you can see the rod through the crack where it made contact on case causing it to crack...
