I have a 07 xr 650 pig. I have bebuilt the motor with a .50 over piston stock compression. hotcam stage 1. I have all uncorked modes done. full xrs only exhaust. running the stock carb. I have tried all different combinations of jets, yet it still feels like its not all there. I get a little hesitation on axcell. and it just seems to not have all the power it should have. My question is the carb I wondering if it canot handle the fuel and air mix required by the motor. Has anybody ran inton a problem like this? Any help would be great.
