I am going to slap on a 520 conversion on my 01 r6. i was going to go with -1 front +2 back. My friend has -3 front +3 back on his 04. Now i have never ridden his rike but it is a wheelies machine. I want to be able to stand it up easy but i dont want to do a back flip if you know what i mean. With this in mind, what size sprockets should i go with? Is my friend just crazy?
