My 11 yo 75lb rider is getting confident and really picking up his speed. Want to improve the suspension and most importantly keeping within a tight budget. I've checked on Factory Connection and Fox cartridges and was wondering if anyone else has had something different that worked good. I've got .27 fork springs and a 4.4 shock all is stock, been experimenting with different weight oils and changing compression settings. He says it's ok but after watching him ride a friends bike who had TH Racing do the suspension he was almost 3 seconds a lap faster on his friends bike.
