14/41 is stock gearing, which is slightly lower than a bolt-banshee is capable of pulling out of the hole in first...But, slightly higher than it will appreciate pulling in second. I'm running 14/40 on mine currently and launch in first. It makes for a decent all around gear ratio, I could go taller for draging but would loose some of my slow speed rideability. I plan on switching to a 14/45 setup and launching in second, nowhere do I ride that I need to go 90...so the top of sixth is really no loss to me. Sand condition, rider weight, engine setup, paddle type and number all play into what gearing will be ideal. As I tell everyone, I can get you somewhat close...but, you'll have to finetune it yourself.
