got a Randonne 125 as demo bike. I have played with it and done some pretty basic things to get it to rev and pull well. Gearing 9 front sprocket, 8 rear, valve clearances adjusted, removed egr system, air filter box mods,re-routed fuel pipe location and added filter, needle adjustments, earth out neutral switch ,restrictor in rear box removed. It pulls me (16 stone) up some big hills. See pics on my website. PAUL
