To stop the gearbox mainshaft flexing when I give it stick and have probelms changing gear , and yes it does work , I did this on my Thruxton Bonni way back then , it worked a treat .

How much stick would you have to give it to flex the mainshaft enough to cause gear-changing problems, especially as these engines have been used in all sorts of competition work for decades, and this mod isn't common or usual.
