I was wondering as more and more miles are getting on my bike engine should i be goin faster and faster ? or will it break in at 12 Mph all the time? im pretty sure it will make a ring where my piston is going slow as it is and if i let it run 100+ miles there will be a ring and if i go faster then it will knock. just wondering ? how fast i should be going atm im goin about 14-15 mph at 27miles on it not sure what to do here?
