[lack of power dt125]

my 03 dt125r 16000 miles only does 65mph, all standard, where can you get that dep pipe? had a dyno check running a bit rich otherwise ok.

[dtr 125 derestricting]

hi peeps ! own a dt125r 1999 model, but the performance should be better ! i,ve read dt125r.net derestricting technicues.however does,nt say anything about carb jetting,surely if the front pipe has been derestricted (ie ring removed) then it would need rejetting ? as its now like a performance pipe compared to the old one.also my bike seems exceptionally slow, 45 to 50 mph without screaming the engine max ! in 6 gear. heard lot of people getting 75 mph plus wheelies.nice, but want to get mine better or at least find whats wrong with my bike,so can fix it ! got 1 size bigger front sprocket coming,as 1st gear is way too low. any help/advice appreciated powervalve turns (clockwise when revved) viewed from l/h of bike,is this right ? front pipe has been derestricted (by previous owner),new plug,starts easily.running out of ideas.seen some dt,s pull away and they scream. thanks

i have also just bought a dt but it is an 03, go on you tube and you will find a video on the pwer valve
