Thanks Cam!!! I have installed a PVL system, which is the entire ignition. Coil, CDI, stator, flywheel, ect. So, I'm stumped on where to look. I have crisped the Jetting, but failed to rethink that the PVL system allows the system to rev about 20% over stock where it shifts the power, and never richened the top-end. Even though it ran great, maybe the semi-lean mixture (for running 20% over stock) and mixed with the engine not warm has caused a nasty seize? I'm out of options it looks like, let me know what you guys think, I'm going to send the cylinder off to the guys that built it and let them see what they say. Anyhow, thanks guys, please keep the oppinions coming, cause I will start to tear into the lower-end now, and need suggestions to just change everything or what.
