Well I read a lot about lifters and hadn't seen 1 bad comment about the Comp-Cams 850-1 lifters, so for $67 you get what you pay for I guess. They are very hard to pump up and still noisy in some areas after warm up. I even tried readjusting to no-avail. So I got to digging around and found a set of Harley B-Lifters I had in a 06 bike with less than 8000 miles on them, guess where there going. :s I'll let you know how it turns out but they looked good after sitting for 6 years or so. I knew I held on to them for a reason !!
