Hi, I'm new to the forum . I joined because I have a dilemma. Lately I found my PGO quad which I haven't used in quite some time (prob 7+ years.) I was thinking about restoring it and eventually make it faster. I was thinking about putting a 70, maybe 90cc big bore onto it. But, here's the problem. It has a separate reservoir where I put oil, quite handy if you ask me. The thing is, would my current oil pump cut it or, would I be able to upgrade it? Also how can I choose which jets I should run? I know, I can go with premix but...I rather prefer to keep the reservoir.
