Nephew has an 09 that he recently lost compression in the mag side. Tore it down and it looks really lean. Mag piston scored up real bad. Stock motor with can and stock jetting. The good cylinder/piston looked lean also.
New pistons along with different cylinders and got it running again. Now it has a miss at 6000 rpm if you hold it there for a second. If you thumb the throttle it will come thru it and go to 8000 and pull hard. From a dead stop if you peg it full throttle it will pull to 8000 and run great. Only hesitates at 6000 until you work the throttle. Annoying.
It never did this before the loss of compression. Any idea's? Thx.
