I'm close to pulling the trigger on a 120. I was wondering if you guys have had any issues with them. I think due to the nature of the beast it might not want to start easy when it's hot.(battery cables?) I'm putting it in a RG and would like to get at least 4 years service out of it . I ride 7-10,000 a year. They might last way longer, I just don't have a clue. I will be increasing compression to 11-11.5 to one, cams to be s&s 640s, FI motor. I'm sure by the time I get 30,000 on it hell I'll be wanting to change something around anyway. If any of you guys have one of these motors I would appreciate any imput you could throw my way. I drove one this past weekend and can't get it out of my mind.
