I am in the process of replacing my cams, lifters, and pushrods. 40k on my ‘07 FXDSE. I wasn’t happy with her performance. Couldn’t keep up with baggers(not SE)off the line and couldn’t catch up. horrible gas mileage, I got at best 33mpg if I babied the throttle under 80 with no hard acceleration from stop. I’m pretty much deaf thanks to the Army so I can’t hear any of the noises you guys are talking about, except for some reason I could hear what sounded like a ping in my primary sometimes at takeoff and turned out to be my compensator(I think, haven’t heard it since I changed the sprocket). I also wanted to be able to tune and when I bought a SEPST and attempted to load a stage 1 tune it wouldn’t let me. Told me to check connections etc. after weeks of racking my brain, tracing cables, and searching forums, I used the tuner to pull the current map. Turns out it’s a MasterTune map. So now I’m stuck with an ecm that I can’t tune, that I thought seriously needed a tune, and to top it off when I ATTEMPTED to load a tune to the bike, it married the SEPST to the ecm. So now I can’t return it and still can’t tune. I bought the bike about a year ago with 24k and not exactly sure if anything was better then because I immediately started making changes. At one point the looked up codes and found that it was looking for the tachometer signal so I put it back on hoping that would help. Not much of it did. I decided on cams. For 2 reasons. First, the performance just wasn’t there. I saw the power band on all the dyno charts and realized there’s a narrow margin for running this setup. Second, the heat is insane. I can feel my ass getting warm on the highway. When I stop at a red light I have to spread my legs and stand or it will burn me through my pants. I read that these engines just run hot because of the exhaust duration on the 255 among other things. Every time I change my oil, which is about once a month maybe every other month, the oil smells burnt and I just don’t see how this is healthy for an engine so I wanted a change. I ride cross country year round and I wanted something that would hold up on those 16 hour days, not something that I would consider overheating after 1 hour. I settled on Andrews 57H cams, don’t ask me why I don’t remember, but it had to do with looking at all of the dyno charts and explanations of what every bodies cams do. Along with the cams came the adjustable pushrods and woods alpha series lifters. I’m expecting to crack open a stock engine and my heart dropped. I saw adjustable pushrods and thought holy chit someone did a cam job and didn’t change the tune. Nope. 255 cams in the chest. And not thing changes was lifters and pushrods that I could tell. Cams may have been replaced but I wouldn’t be able to tell. I know the tensioner pads were insanely grooves so I’m guessing nobody went into the cam chest. Lifters looked pretty new. No brand on them just a long number. 5100xxxxxx I think. Anyways I put the new lifters in. They say you can only put the. In one way but I don’t see how. I guess I got them right cause they work, but they look like they could go backwards. Breather screens were full of oil replaced them and the umbrella valves. Installed rocker lockers. Installed a mechanical OP gauge. Installed the new cams and a fueling relief spring and plunger. Changed the oil. Made sure I primed the oil system all the way to the filter before I ever tried to start the engine. Married a different ecm and loaded the tune from my PV1. Started her up and oil pressure climbed to 60 within 10 seconds. Maybe more, but the gauge only goes to 60. So after much stress, tearing it back down twice to adjust the fueling spring and the put the stock back in, I’m told it’s normal. Especially a cold start with new oil on a cold day. So I’m just waiting on an updated tune with my cams on it and I’ll be testing her out. The few seconds I’ve heard she sounded great but the timing was probably off due to tune being tor 255 not Andrews 57. so who knows when I get her timed and tuned right. Don’t know if she had a lifter failure or the dealership I got her from changed them for a CYA. Either way they look brand new. I will be double, or is it triple, checking the valve lash one more time before I let her run again and warm up. I’ve done that with pretty much every step. I’m a little OCD. Took me 11 days with a few all nighters to get here now. I decided I was not going to rush and miss a step. Too much damn money involved. Anyways I will update on how I think the lifters perform, and the cams, when I get her running again. Hopefully today or tomorrow.
