However, if a big part of your motorcycling hobby is playing with the engine to see what changes make what difference regardless of whether its a cost effective way of getting better lap times, then that's what you're going to do and i'd be very interested in hearing about the results when you try it.

Hi Hermit ,

I enjoy working on the bike . Our bikes have been put into another class so the rules are now open to a degree . At some tracks we race with anything up 1990 .

We don,t find rs 250's here . I should have bought one with all the money i have spent on the nsr !

I am very keen to do this mod and will post my results when i have finished .
