Thanks for the first impression. Hope the two up ride is a good one!
Wish Andrews made a gear drive version of the 48H. I'm a big fan of getting rid of as many moving/adjustable parts as possible, and the simplicity of a gear drive really appeals to me. The 48H grind seems so right for a bagger, that I'll likely buy one, even if they are chain drive. Like you, I'm a solid pushrod fan. It takes 5 minutes to pull the gas tank off a new FL, and the rocker boxes aren't near the headache they used to be. I doubt the added labor to use solid rods, is much more than the cost of the adjustable rods. Unless someone is a member of the cam of the month club, I just don't see the point. What intake/exhaust are you running? How about a tuner/PC-V? Thanks again for the hands on review of this cam.Yeah, I did the inner cam bearings. The tech said he was glad I did, and he won't do cams without new bearings. I have ~11,500 on the bike, and you can already see wear on the old cams where they ride in the stock bearings, kinda scary... I used the stock pushrods, I've had one adjustable pushrod fail, and another loosen up on me in the past.
I know what you mean, seems like there is always one more thing the bike needs. Love or hate Harley Davidson, you have to admire their marketing plan. They sell you a bike and give you a phone book size catalog full of other things you didn't know you needed, until you start looking...
I like those Agitator wheels, should look nice! I keep trying to find a set of take off Limited Chrome wheels, no luck yet...
I believe that is why he suggested a 54. However, upon doing more research, I believe I will still go with a 48H. I'm looking to have Branch-Okeefe do their "PT" package on my heads. It results in a 9.5:1 ratio, so the 48H should still be fine. This head package is intended for touring bikes, and the power is mainly from 2000-4000 rpm, which is where I spend a fair amount of time.Interesting. What I told them was that a 103 was likely in my future, but I was sticking with stock heads and compression ratio. They recomended the 48H.
I just checked HD's page and they show a stock 96" motor at 9.2:1 and a stock 103" at 9.7:1
What kind of head work are you considering? I wonder if that is why they are suggesting the 54 for your build...
I think I'm going to shelve the cam purchase, until I do some more research. I don't want information overload to cause a panic purchase. Have all winter to think it over. If Gary suggests a CR of 9-9.25 for the 48H, perhaps the 54 would be a better choice for me. I think it'll be easier to find a piston/head combo in the 9.5 range. I know one thing, before I even try the +4 advance gear, I'll have to measure the cylinder pressure, to be sure it's not too high(over 185psi or so). My head is so full of cam info, I think I need a compression release for my skull !I used the factory pushrods.
My plan is a cheap build, for lack of a better term. Head work is expensive, so I'm trying to avoid it.
I sent this to Andrews:
I have the cams installed and really like them, definite increase in power right where I wanted it. I had planned on installing a 103" kit on the bike in the future, but I have a concern. I know the stock 2009 96" motor is around 9.2:1 compression. A stock 103" Limited is listed at 9.7:1 and Harley lists a 2011 Road Glide Ultra at 9.6:1 The HD P&A catalog states that compression releases are recommended when using their 103" kits. I have no intention on doing any work on the heads, and using the head gasket that comes with the kit.
If I install a 103" kit, will this be too much compression to work with these cams? If so, would an automatic compression release solve the problem?
And this is the reply from Andrews:
It may be wise to get the compression ratio down to 9-9.25:1 with after market pistons - you'd have to look into what Wiesco, CP, or KB have to offer. Compression releases won't change the engines running cylinder pressure, only the cranking pressure. If you fit the 103" with the lower comp. pistons you'll be fine, and not only that, you'll have a very dependable, low rpm torque engine.
So, I guess rather than buying the 103" kit off the shelf from HD, I need to go in search of jugs and aftermarket pistons...
