Stage 1 with andrews 57's
#41
have only got to ride about 200mi since install due to weather but I am happy with them. notice a bit better low end and also seems to run a bit cooler, can run regular in cool weather with very little pinging. also Jamie at fuel moto sent me a good tune for the power vision. waiting to get more riding time to really get a feel of the cams.

no argument there as pinging is very bad for a motor, can burn hole in piston if excessive. what am saying with the stock cams and tune for stage 1 I would have to run premium even in winter and then be careful not to lug.. with the 222 cams and tune tried running with regular in cool weather and only get detonation if lugging hard. am waiting for warm weather to get a real test with the wife on back and loaded for a trip.

Intake reversion and rocker shaft ticking are two completely different sounds. If the rocker lockers solved your noise it wasn't reversion. Only way to muffle reversion is with a more enclosed air cleaner. I run Woods 777 cams with an Agitator cleaner and rocker lockers and have intake reversion. It's just music to my old ears. If I'm not mistaken the Andrew's 57's are noted for intake reversion.

I have been using the 57's for about a year on my 103 softail and haven't noticed any popping through the a/c (just a bit of decel pop I kind of like). Not really much different in valve noise from the 255's for me, but I did change lifters (comp cams 875 adjusted 1 turn from the bottom). I'm going with a 2 into 1 exhaust next week and I'll see if anything changes.

Adjusting up from the bottom of a collapsed lifter one full turnn on a 24 tpi push rod you're only allowing yourself .041" . Your preload is actually between .155" and 158" which is a lot of preload. You're not giving yourself a lot of cushion there you might want to back that down 2-3 flats to bring your preload to roughly .140"- .146" . Your playing it real close..... I wouldn't over rev it till the motor is pretty warm..

Don't worry about the adjustment.. I've run 875s at 1/2 turn from bottomed without issues. One thing good is that the lifters won't collapse too much at higher Rs. I have to run Johnston lifters at about the same preload or they rattle like heck at 4500-up. WFOLarry started selling sets of the Johnson lifters with travel limiters for the same reason I suspect.. BTW. 875s are travel limited to about 0.12 inches. The are designed that way to keep from pumping up on a non rev limited motor. The only thing that will likely happened from running them that low is that they may not last as long before they start to tick but the 875 were still quiet longer than SnS regulars for me when I was running Crane H290s in my RK.
