I have read how if you run an aftermarket filter with exhaust and lid off you will run lean w/out CB and EFI controller. I have a HMF slip on, Pro design intake with K&N filter, lid off. I only run a cherry bomb and it seems to run well. It does not pop or give me any indication it is running lean. I would like to make sure I am not hurting the motor running it like this. I have run it this way since new in 06. Thanks for your help.
