Just wondering what gear combos/ratio people use ? Currently running stock 13t 48 but feel like I’m running out of gear length quick ?

A 14/51 would give you a little longer pull from each gear. A 14/50 would probably be your best compromise between more top end pull and not killing your out of turn performance. As an added bonus going to a bigger front sprocket changes your chain angle and puts less bind on the rear suspension allowing it to work better and absorb the bumps under acceleration better.

Here are the ratios.
13/49 3.77
13/48 3.69
14/51 3.64
13/47 3.61
14/50 3.57
14/49 3.5
