So I threw in these weights on my 16 pro 163, put the magnets in 3-3-2 for 64 grams but now around 8000 feet i'm only pulling 8000 rpms. From what i've read removing some tip weight could bring back the rpm. Primary spring is 120/320 and 170/240 Secondary w/ a roller bearing I normally ride in BC in the 6000 - 9000 ft range any insight would be much appreciated!
