When riding in the woods on my L , i get stuck dropping to 1st gear because the gap between 1st and second is too much to run in second in tight woods. Do i want to drop a tooth on the front or back sprocket to tighten the gap without radically changing the gearing (stock) i have now. I run 60/40 street/trail. Also , is it OK to cut the stock chain and add a master link to accommodate the smaller sprocket(s) or is a new chain needed ? I prefer a master link chain , can pop it off , clean it up and lube it so much nicer off the bike.
