My ktm BIG BORE 212 is Running poorly. Prior to the BB kit the 200 ran fine and was just torn down for a rebuild. After installation of the BB kit I disasembled the top end and checked the PV alignment and every thing looked fine. With the PV opening I am looking at jetting. I have to really
REV it in a lower gear to get it to respond, otherwise the midrange flattens and hesitates. Seems like maybe too rich of a needle. If I lug the motor it hesitates and I must clutch it to get it to open. The cylinder looked fine when I pulled it off to check the PV. I have also set the Z adjustment to 1.81 inches. Lots of grunt down low and top end is good, just a flat mid range.
Where should I go from here ? Any suggestions ?
Jetting: DDK needle
42 pilot
182 main
stock pipe & fmf silencer
Vorce reed block.
