Its not just the deristriction wire that you need to earth you also need to do your air inflow pipe your exhaust and possibly your your power valve but its not always needed if it has not been adjusted before

Hi spammy
You need a new deristion pipe and large expantion chamber, next tek the little restrictor off your air inflow pipe,
then pin your power valve open, dont touch the gears they are a bitch and fuck easy
if you find anything interestin gimi a shout i want mine to be tuned to the max

I've researched the DTR 125 as yet no one has posted specs mostly mpg is bout 70 to standard tank without reserve.
top speed when fully derestricted is about 85 without blowing it up like which model have you bought
