    So, will this magical camshaft be mass produced? I have the SR max 300 with the malossi head and cylinder and am looking at getting the Polini cam for that as well. I also have the Malossi O2 TC controller which helps a bit I have noticed. I am also looking at getting a second hand throttle body for boring to increase airflow. I would like to change the end gear ratio a bit too as the thing just revs too high at high speed. Not much info on these things though.

      I’ll try and find out Tony. I’ve recently ridden a 24bhp GTS and will be doing a feature soon, I’ve also got another one to do that may well push close to 30bhp.
