I got you to exchange Sleeve with Bore upService. I exchanged carburetor for PC 20 and had difficulty setting up, but now I have come to the point where somehow compromised. Engine Power has a feeling of raising to about twice. Previously it was possible to run Torque fully even at 4000 rpm that I could not run unless I had to rotate it more than 8000 rpm and I will go to the Red zone. I finally got to LEAD what I was running running on the current.
