So I have a 260lb rider on a kitted e50 magnum. Running an uncased matched 70cc kstar, 15 sha, boss pipe, tighted 2 shoe, and 15/45 gearing. It is kind of sluggish off the line. What really sucks is he lives in a hilly area and needs to get moving. I know a ZA50 would have been better, but whatever. So my question is would a techno circuit or estoril help his overall takeoff? I dont care to get past 35mph, just climb some hills. The boss is really killing the lowend. I'm on a budget and he doesn't want the screaming loud proma circuit. Also would replacing the 15 sha with a 14.12 help the lowend. I know bings are an option, but i already have the 14.12 sha.
and yeah this is for my father.
