My question is on our 2005 kasea we have elka shocks with resi. The rear shock seems somewhat soft but rebounds good. The bike sits really low in the back and we want it to sit higher. If I could get the rear up about 2-3 inches it would help tremendously ,first so it wont bottom out coming off BIG JUMPS and second so my sons legs are not so cramped. Is there anything I can do with the elka shock to sit it higher? Thanks
