Buy unorthodox racing pulley...timing marks are dead on and they are billet one piece machined items. They don't need to be balanced because they are billet.
FYI...fidanza flywheel is not stock so I guess we shouldn't run those right? I mean what do race teams know
You will not spin a bearing due to a pulley unless the pulley is fucked up like your stock one is right now. The stock honda pulley is not a harmonic balancer either.
And if you want to go the route saying stock is better because of the THIN ass little piece of rubber in the pulley...then why did honda release a CTR pulley?
Get an unorthodox racing underdrive pulley and call it a day...they also come with the paperwork for belt part number needed for the pulley.
