My recently purchased 2004 Mastiff has 21,000 miles and I don't know it's history. I was thinking about changing the lifters this fall if not sooner. Looking under a pushrod tube I have adjustable pushrods (which do not appear to be quick change pushrods) I was curious if anyone can tell me if adjustables were stock in a 2004 107". I don't know what cam is in it but it feels very cammy and fast, almost sounds like it may have roller rockers, certainly it's not docile like a mildly hopped up Harley.
