I've got a 103 with Crane 570 lift cams, took it apart to put in the SE cam plate & tensioners this fall at 68K miles, everything looked great including the cams & lifters. If you use quality parts & maintain the bike well you shouldn't have any problems, quit worrying & ride.

Guys, thanks for all the replies! The bike runs strong, just need to tweak the map a bit. I will be doing this in spring!. Regarding the question about why "Stock B lifters" I was told these are very reliable. Is that not the case? And is this the weak link in the build?

i have a great combination in my 103, and i also believe that there is a happy meeting point between longevity and performance as long as you don't go overboard. i'm using the hd 259-E cams with .579" lift, and 10.75 compression ratio slugs. it's a comfortable and fast bike, for a dresser anyway.

Can these be one in the same? Specifically I am after some information about high lift cams. As you can see in below what I have in my 06. A couple of years ago I blew a S.E. style lifter that took out my cam, cam plate and the oil pump. I was told back then that these S.E. lifters were problematic and this was the cause of failure. Recently I have heard that the high lift cams like these 585's are hard on the valve train and may cause another failure.
I am looking for some feedback from you guys that run these type of cams and looking for opinions if I should be redoing the build, and if so with what?

Stick with exhaust, intake, Power Commander or similar and external components.

You should be ok with a .585.After you install the cam make sure you check the the piston to valve clearance. I run a .660 lift in my bike, & bigger valves,but my valves geometry has been changed!!! You need better lifters.I would go with the Fuelings or the Wood lifters.I run the Wood's in my bike!!
