hey guys, havin a little bit of problems tuning my shee, just put a set of .020 over aggressive dune port cylinders on my shee, heres the details on the motor
.020 overbore aggressive dune port
stock stroke
stock head
stock carbs with 250 mains, 25 pilots, needles on the 2nd from the bottom clip
stock airbox w/ k&n filter
running 159-161 compression
91-110 50/50 mix at 32:1
elevation is 1055 ft asl
i started off with a 280 main and it was running super fat, so i dropped it down to a 250 but i cant really tell if its running fat or lean...it wont idle at all, you let off the gas and it falls flat on its face, i havent tried running brand new plugs in to tell weather or not the 250 is fat or lean but i will tonight...but im more concerned with the 1/4 to half throttle response because it spits and sputters untill you really crank on it then it clears up and runs like a scolded ape on the top end....any ideas would be greatly appreciated because im running out of ideas
