I removed one weight from each lobe of the variator. I don't notice any vibration. I imagine that with only 19.5 gr I get the rpm up pretty fast. I doubt if it is optimum but it is a Sunday and I am in the middle of no-where. I am not worried about focking up a 900 dollar scooter. The lightweight piston should turn lots of rpm.

Between my wife and I we have 4 other two strokes including my prized 83 RZ and 75 RD 350s ex roadracers, both were purchased new, I quit racing them in 1984, life took over. She has a 50 Suzuki 5 speed and a Honda Elite with an 86cc stroker. I put a CR80 pipe on it. My current street bike is a Yamaha SR500, it will do the ton on a good day and has loads of midrange. I have sold all my big bikes, what is the challenge of making a 165 mph bike faster? I want to ride hard and get no tickets.
