125-specialist mechanic

this is normal the dt is geared to high in 6th gear for performance it is designed for fuel econmy which im not interested in i want POWER!!!! there are ways of getting more power such as getting the barrel skimmed down by about half a mm to increase compression and modding the crap out of it, most power ive had is 47 bhp at the rear wheel but the reliabilty was so poor it was useless it lasted about 3 days before the piston melted. dont go too far with modding its pointless to a point

just go one size up on the jets there are numbers stamped on them that should sort it out ash
