I have a 2000 zr440 orange white primary spring updated weigts (-1gram). The secondary has a bmsxh with one shim and a green spring in 4th hole.+1 degree timing with 50/50 race gas. Good belt and tight deflection. My problem is it only runs up 8500 rpm. Shouldn't it run out at 8800 rpms? I removed 1 gram from the weights it helped a little. Any ideas? Thank You in advance.
