Hey guys just wandering if anyone out there has tuned their sleds using stock yamaha weights,springs,etc.I am currently running stock primary with yellow/silver/yellow and stock secondary with white spring set at 90*.Its pullin hard and good backshift but once in a while when i hammer down it hits rev limiter then i have to let go.So i was thinking about adding a little primary weight...thxs for any info
