Well, I finally did it while checking my valve clearances. I am happy with it (I think). I can hardly ride it because of my sprained ankle which I can't even put on the peg yet, so I rode with it hanging off the side. I noticed it reved quicker and spun the rear tire more easily. More snap and less traction now. I think I like it though. Didn't really notice any low end loss. The jetting seems to be good with 180 main 48 pilot and can't remember the screw setting. I am at sea level to 1000 ft. No popping or backfiring. Little less engine braking.
I have the Big Gun
oversized system with airbox cover removed and no throttle stop (Canadian) Too loud so I am going to get a quiter core. I just have a couple of questions which might sound stupid, but would like peace of mind. I advanced the left cog (when looking from the shifter side) on tooth clockwise (right) Is this correct? I am sure it is but it is lingering in the back of my head. I am thinking of going with the superquiet core (Currently have the competition core) How is this going to effect power (ie less snap, less low,mid, top?) I don't know what to expect. How will I have to change jetting if at all. Go leaner or richer and where? The competition core Big Gun
Silencer is redicilously loud. Louder that any YZ I have heard by far. So just want to let you guys know. Thanks for your guys help, Marco
