I have an 06 M7 with 1000 miles with low end bogs. It runs great starts 2ND pull every time. runs good, other than when your just cruising along at a low speed and punch and it will cut out. will almost throw you into the handle bars, then it will take off. I'm also not getting my full power out of it riding at high elevation i'm only getting about 6500 rpms. I had 68 clutch weights in it, at the end of last year i put 65 weights to see if i could get more rpms. But i never got to ride it again, everything iv been reading about these is that you can loose a lot of bottom and power in clutching. Thanks for any input
