I have not had this problem with the stock dunlap. I threw on a set of michelen pilot powers and set them to 35 psi each. Now when i ride a wheelie the bike seems to want to lean to the right side. Should i lower the tire pressure a little bit. I am not a full out stunter i ride twisties all day. I have a very neutral riding postion on the bike so i dont think that is the issue. and ideas!?
