Here is my dilemma , I talked to the HD tech who has many years experience on building v-twins , he is now the service manager . I asked him which cam he thought I should use and he said the se255 would really wake my bike up . What I have is a 09 night train , V & H big radius , se heavy breather and the HD reflash or remap as some call it . I know some will say I'm running lean but according to my plugs I'm looking good , hardly any decell poping . Here is my questions , 1st is it really worht the $700-800 bucks , 2nd is changing the cams going to cause any excessive wear on any other enginge components , 3rd do I need compression release now , I don't think I do but still want to ask . I'm not trying to turn it into a racer by any means but thought the extra torque might be nice . Also if anyone asks our gas here , premimum , does not have ethenol in it , the stations do sell gas with 10% ethenol but our regular and premimum do not contain any , so is it really worth the bucks ? I'm open to all opinions .
