  1. Need carefully set up when over bored, Fi engine is very hard to get past the flat spots. Exhaust is more than likely the biggest waste of money as I am sure you have noticed the port in the head is very small. Have gas flowed a head which brought with it its own set of problems (ignition adjustment is not very easy) but yields moderate gains without causing any harm to the reliability. But the suspension, brakes and poor choice in tyres are the biggest limiting factor to going fast on a ybr!
