I guess it's possible to make the older parts fit, by bolting in or adapting other older parts. I'm not so sure that's a good idea. It may turn out to be brilliant. But in theory the new parts are an advancement of some sort. And like any other new design, the aftermarket will soon be there to support it. The '06 engine has only been on the street for a few months. Give S&S time, and they'll figure out where the weak links are, how to fix them, and how to make the current design better. That's what they do. And they do it by extensive testing, and R&D. For example, looking at the new cam plate I can't say that it's a better idea or not. I could take an educated guess, but can't say for sure. And I don't have the time, facilites, or resources to do the testing. I'll wait and see what they say.

HD made some obvious improvements in the 06' to the TC88A engines, along with some cost cutting measures. They revised the oil pump(which now scavanges oil much better and flows a bit more as well)slightly, they revised the cam tensioner system, which should give more uniform predictable wear patterns from engine to engine, at the same time they also replaced the outer cam bearings with plain bushings. I am not a fan of either. Best thing to do here is just put in some heavy duty Niche outer cam bearings altogether. So overall Ill call the camplate a wash. The new tensioner system may cost a few more pennies, but I bet you they compensated the possible extra money spent on tensioner system by putting in those dirt cheap bushings. Best thing to do either way is to toss the system entirely and go gear drive. I never liked the chain drive setup, no matter what year the bike is.
ORIGINAL: bobcowan Light weight undercut valves and springs make a big differance in a V8. But that's 16 valves, and not 4. In your experiance, how much of a differance does it make in these motors?
As for the bee hive springs, they are the bees knees. They are lighter, more durable, and stronger than standard coils. Standard hydraulic rollers will start floating the valves around 5,800'ish. These springs extend that up to around 6,400'ish. That's a huge improvement. And because they are lighter and have better harmonics, their closing seat pressures and transient pressures are lower. That means less parasitic losses and less wear and tear on the cam drive. I'll be upgrading my V8 to these new springs this winter.

i found the right combination atleast for me, i treid out my freinds 05 low rider dammnnn.. it pulls.
he says it is a 95" with se high comp cast pistons, se 204 cams, se performance heads ( that i saw on the heads ), power commander and se II slash cut,he told me that it has 92hp and 103ft on the wheel (maybe ?) i think i am going to use the same set-up but with my stock heads (they will be ported and flowed) and other pipes.
