rode over to my son's tonight we installed new bcm filter and PCv. i got the bike ready and he installed the PCv. i did the filter . the bike doen't seem to have any more power, but the off throttle burble is gone. response is very smooth,now. with the 200 rear tire and the smoother throttle the front isn't quite as light as before, still comes up easy in first, but not as easy. still get a rise in 2nd at 10,000 or so.very happy with this mod.now, just have to wait for muzzy. oh well. will post fuel milage as soon as i run through a tank.
