Gear reduction?

Well i have to tear into my rincon to fix the final shifter that is giving me grinding when going into gear (D or R). So since i have to go into the tranny, i was thinking of doing the BRGR and maybe trying to trade or get my self some more aggressive tires of 27’s or 28’s. Whats everyones thoughts?

With the BRGR and 28" tires, the top speed would be around 50 but right now with my 26’s, at full throttle, i can only get up to 55 in fields that i ride, havent tried on a road yet. LOL
