Hi, I know this is but of an old thread but need some assistance. My xvs 125 is lacking power and I suspect the pickup coil to be faulty or out of resistance, does anyone here knows what the reading should be when checking the pickup coil? Had to do a no-2 cylinder rebuild after the cam shaft driven gear rocked loose and came off.. after the rebuild it's not been right? But she has good compression, timing is spot-on, valve clearances seem good but will take measurements for those as well so I can reference to mine to be doubly sure. If those two I've asked about match others readings/measurements then the only other thing I can think of it being us the ICU/ECU Can anyone offer any help on this? Thanks in advance!!
