Timing chain help!
that maybe what I have to do. Do you know a part number on it? I couldn't find the gear. Thunder racing sells an oversized gear. But they do not say how much oversized and have not e-mailed me back yet.
This is for the vented opti timing chain setup at least, not sure if it would fit the unvented opti setup chain. The difference might only be the upper gear on the early timing set I just don't know for certain.
