Im new to this site,Waited till im 50 to finally get a Harley.Bought used 2006 classic with 16k on it.I've been riding it for little over a year now and this condition has started over time. Has new plugs installed. Checked injectors found to be updated #s. When I spray throttle body cleaner slowly on top of front head to manifold flange engine will slow and die.Looks like o-rings need replacing.Can anyone tell me whats involved in replacing them.any other suggestions pertaining to this model year.Thanks

Welcome to The Forum, This is not a hard job if you have the right tools. Clean and tight, alignment before tightening is critical. Use good gaskets and go slow:s
