Hi I’ve currently got a M8 FLFBS Fatboy which is stage 2 with a S&S 465 cam. After the cam was fitted I changed tuners to a Thundermax. My issue is that the bike is pretty poor at low RPMs or constant slow speed. It bucks and jerks a fair bit. I’ve had the plugs and leads changed and don’t seem to have an intake leak.
I’m wondering if anyone has any input on timing or AFR I can try with the Thundermax. I’ve done a good few hundred miles with Auto tune which did help a bit but the issue seems to be intermittent. Some have said it’s the cam but others have said they have same set up and ride is smooth so I’ve come to as for any Thundermax gurus for advise please
