Harley knows they have a problem with their pressed together flywheels. They have changed acceptable shaft runout to .010" on twin cams which is horrible. They must think their sportster wheels are pretty tough, leaving the max runout at .002". I twisted mine up pretty good at .012" and .0185". I sent my new wheels out to be plugged and tig welded because I dont want to deal with this bullshit again. http://www.darkhorsecrankworks.com/ is the best in the business and will setup your late model wheels. Ask for John.
