I strongly recommended NOT changing the stock front sprocket or chain size for safety reasons. Just my opinion.

From memory i'm on 15 38 on my 6R.

I did briefly try a 14 tooth front to test the results before investing in a rentahl rear sprocket carrier. Larger rear sprocket for same results, less stress on chain and safety reasons Shazaam has expressed.

Front wheel comes up very easy
