Have a question,

Why do they delete the oil pump? is it that unreliable at high rpms?

Today, we have better syn oils that are able to give great lubrication right up to 100:1. I run 50:1 in my modified Husqvarna TC250, and so far i have been happy with it.

Would it be necessary to delete the pump, or would i be able to keep it for street use?
