Cam upgrade
High flow Kury with K&N filter, Rush slip-ons with 2" baffles, Jackpot stainless/ceramic headers and a PCV. Bike got tuned when not that hot. IMO, the tune could pull more HP out but the 551 is a torque cam anyway and pulls great up to around 4500. That equates to the 120 MPH range. I know my speedo is off about 1% but have had the speedo at 130...... fast enough for me....

Torque cams don't lope as much as higher lift cams. But it does some. I can't even remember how much the stock cam ran now. LOL. Also, some reversion, which I have gotten used to. Bike runs great, is responsive and like I said, has enough power for me. For me, I started asking people what they had. I rode my buddy's bike with SE255 but my tuner sponsors S&S. So here we are.

I'm finishing up Anderson 57h cams in my 2012 FLHR Road King. Did some research and really like the midrange to top end pull. However many are jumping ship for more lower end torque sacrificing top end power. I simply installed a +4 advance sprocket that changed cam timing to 1800 to 5200 rpm's, without advance sprocket (straight up) 2200 to 5600.
If you flip the crank sprocket over to - 4 degrees, 57h will come in at 2600 to 6000.
All your doing is moving the span 400 rpms (in my case) to the low end allowing the cams to come on quicker. Now have the best of both worlds IMHO, it's the perfect bolt in combo, should be done by next weekend. Will post results.

Just installed 551's in my '10RK which already had a stage one and can't believe the difference even though I haven't been to the dyno yet. Very strong pull and just what I was looking for. Downside: 28 mpg! course I've been having fun playing around. Gonna take it easy on this tankful and see what the mileage is. I think it will improve if I lay off the throttle.

I have the same cam advanced 4 degrees as well. Did it about a month ago, but I have been running a map for a set of SE 204's since. I am actually dropping it off today for the week to get dyno tuned. I'll looking forward to the results.

Agreed, but was really pushing the bike . Also the plugs do show a little rich but going to the dyno to straighten out.
