Dreflu - Don't risk that new cylinder with the stock oil injection pump! Moving up in CCs changes the motor's needs - ESPECIALLY if you have to rejet/replace the carb.
Disconnect it and run premix, dude.
thanks and i did... before i even started it.... but i think i still ruined the cylinder. it was testing @ 150 lbs yesterday and today its down to 120 and wont start. im trying to find piston rings for the malossi kit now. i did something wrong somewhere. i had it pre mixed. and had the oil pump hooked up to start. im buying rings to try it again and if i still have no luck. she's getting parted out. and im going back to 4 strokes!!
