i been fucking with my 2* power vavle and now my bike seems to die and splutter when i hit 75, its fully standards, exept for the wire earth, any1 got any tips to adjust them back to normal ??? or even better tuning tips ? for the power valves, ive herd number 1* is top speed, and number 2* is accelration ??? thanks alot.

also can any1 give me some tuning tips please as ive heard fully tuned up u can do 100. thanks.

firstly you wont do 100.

Secondly you want the powervalve cables done up so the cables are firm with a little bit of slack (not much) it should open and close freely aswell, if not remove and greese up.

Theres not really any tuning tips but it would be a battle against performance and reliability of you do loads of mods.

Do you know where the powervalve should line up? (have you had the cover off)

this should explain how to set up your powervalve correctly http://www.dtr125.net/workshop-manualf.htm

If you want real power, pass your test and buy a big bike !
