CompCam Lifters 875-1 or 850-1?
« on: July 05, 2013, 11:20:46 AM »


Which one for this setup. '02FLHRSEI Factory-TC95, 16953-99A SE Heads at 73cc, Head Quarters HQ-0039G cam (.575" lift). 9.6:1 corrected compression. Stock lifters and SE adj. pushrods. As a preemptive measure, I installed B148 inners into the right side cases with only 4K on the clock. Then in '05', I had removed the chains at 21K and I never had a failure. 69K on the clock now and I picked up and intermittent noise on even light acceleration. I did strip the wind screen and Even though it is a right side noise, it reminds me of a loose compensator nut clicking under load, But I opened the primary and eliminated that. Exhaust covers the noise under moderate and heavy acceleration. So I am thinking bearing, possible lifter, I wont look above the heads till I see what's going on in the cam case. Changed the oil to find a rice grain sized, metallic trash on the magnet, the trash was bright and shiny and on top of the mud that is normally there between oil services', so I got to it quickly. I am going to open the cam chest and look. I will replace the inner cam bearings (at $6 apiece and only 15 minutes to replace, why not) and make a decision on the outers. The top has been really noisy for the last 10-12K, so I will replace the lifters first. My compression is 135/145, both jugs which sounds a bit low but, because they are very close together and consistent I will suspect the cheap gauge. The engine consumes about 4 ounces in my 2,500/3,000 oil change interval so I am not going to bother with a leak down test, (no smoke at all) I do a seafoam treatment every 10-15K...
Which lifter would you pick? Why?
I found a set of 850-4 for $51 does that equate to 4 each of the 850-1?
I also see that if they are labeled for Harely they cost$15, if listed for Chevy $12 for the same part number 850-1

I would use gaterman 1023s,S&S, Woods.  Did you open the throttle body when you did your compression check?  Not sure where you got your compression numbers but when I run the number I get 10.6 static corrected to 9.9 and 210ccp. I would recheck compression with a known good gauge and if its still low perform a leak down.
