Reason for RPM Loss?
I've lost about 150 rpm's since beginning of last summer. My compression has steadily risen (from 135 after to 147 now) since a complete topend overhaul 2 years ago but my intermediate pump shaft bearings just gave out (completely disentegrated). I think they've been steadily going out. Could this have been the reason for the rpm loss? Ski is 2001 GP1200R. Two years ago the ski ran mid 70's in the cool dry air and low 70's in heat.
