Just got done rebuilding another e50. I was about to through a k-start 50cc on it, and it occurred to me that I never try for max performance, even in a kit. I'm talking close to stock setups mostly. Chuck a 15mm intake and one of those stock looking aftermarket cigar exhausts, upjet until I hear four stroking, and I get about 35ish. I generally run things a bit rich. Let's pretend that I care about high performance for a second and I tune it accordingly. How much more performance can I squeeze from this basic setup? More to the point of this topic, all else being equal, what is the most I can expect from a stock 2HP top end?
