i have a 91 dt125r with a 88 engine i bough a power vale servo from a dt but its the 5 wire one , it came with a tzr125 control box which i have wired up and appears to work wot i would like to know is wot the valve should be doing when engine is running
thanks r0bsk1 well sorted....... using the tzr control box should give different power and toque bands to the standard dt set up so i may well have to play with final gearing
