Hello

Does the DTR require battery power to operate?

Mine has the PV pinned open and no servo assembly fitted.

Bottom to mid range is rubbish and i assume it is because of the PV being pinned.

Any suggestions as to get around this or do i need to fit the servo?

Could the PV be pinned to halfway open?

HI, Find the manual for this bike and set the power valve up as per original. The clever little Japanese folk new exactly what they were doing at the time of manufacture. Pinned fully open is the equivelent of removing the variable valve timing on a 4 stroke. Can't imagine anybody rushing out to do that! Power valves were once pinned full open in some forms of roadracing where you were at maximum throttle for most of the time. Hope this helps.
