You can go as low as 11 tooth but I've gone for 13 , 16 seems excessive for a 125 carrying a 210lb rider , it would never had worked .

Thanks guys for your input , I'm happy now that the poor throttle response was mixture ( air screw adjusted to suit) then I found it had a 16 tooth drive sprocket which meant pulling off required more revs and clutch feathering . Totally happy now, she's perfect. Thanks again

Thanks for quick response Nev . Looks like more investigation work needed as the power valve seems set up ok from the outside . Servo system fully operational ie it has the "clean cycle" when ignition is switched on . Not yet looked up the exhaust port to see if the power valve is present and correct though. Thanks again mate .

Hi , I'm trying to get my Dt 125 r road worthy after being bought recently , happy with everything apart from there's no bottom end power , not much mid but a huge power band ? . Surely I can share the power better ? The previous owner has fitted a full dep system. Any help would be great .
