EVO Mods - Thoughts?

[RG09]

Picked up a mint 1999 Heritage Springer Softail in stock form. Plan on doing the following:

- Screamin' Eagle Pro Breather Kit
- Screamin' Eagle Pro 42mm Flatside Carburetor (Mikuni)
- Andrews EV27 Cam (with Torrington bearing fix)
- Screamin' Eagle Quick-Install Pushrods
- Kerker Slip-on Mufflers (fishtails, of course)
- ??? Ignition

Looking for nice low- and mid-range boost, but mostly want reliability & longevity. Will do headwork and the like when a top-end rebuild is needed (if ever).

Five questions: Is that carb the same 42mm carb I'd get directly from Mikuni? Will I regret the EV27 over the EV23? Is there any good reason NOT to go with the Kerker mufflers? What's the most reliable bang-for-the-buck ignition? And should I go with Iridium spark plugs?

Thought I'd knock this all out at once, thanks.

Other than the SE logo on the slide top, it's the same carb. IMO, you don't need it for low and mid range, the stock CV can do that for you, but if it doesnt have a jet kit and good air cleaner already, getting it set up may approach the price of the Mikuni.

I really like the 27 cam, it's not bad with the stock compression, and if you ever have to take the heads off, milling them to raise CR will really wake it up even more.
Don't know anything about the mufflers, but generally the fishtail tip seems to hurt power somewhat over a more conventional tip.

You're not going to see big gains right now in an ignition, the main thing is that a performance ignition will raise the rev limit. Be nice to get one with tunable advance curves though, for future upgrades you may find yourself doing.

Once you get going with mods, it can be hard to stop.

New lifters of course and a SE ignition module will be just fine for a looong time.

Like hightop says, the carb is a waste of money, the stock cv is the way to go. you wont regret the ev27, and take the money you were gonna spend for the carb and put it toward headwork, and the bike will feel like it should have from the factory. I have a screaming eagle module if your looking for one to fit that bike, and ive been seeing a couple of arlen ness big suckers going cheap on ebay, same as the se one your mentiong, so may wanna look into that also, chad.

There isnt much to a cv, seriously, i like to run a woods needle, 46 pilot and about a 180 main on a stock motor with a ev27, and if winter gets to awful long, ill even polish the slide. but thats about all they take to make them run.

can't find the guy on ebay now...was gonna link and see what you guys thought.

I've considered "downgrading" from my S&S to a CV...

You won't regret the change from the EV23 to the EV27. I did the exact same cam change with mine. The EV27 seems to make much more usable power, by the "Seat of the pants" dyno. Really nice change in mine. I can give most 88-inch twin cams a damn good run for their money. Hard shifting from 1st to 2nd, I can get the front tire off the ground...

Also, I have to wonder, why are you using all the Screamin' Eagle parts? There are a bunch of aftermarket parts that are just as good, or better, for the same or lower cost.

Ignition module could end up with a thread of its own when you get into Single-Fire Vs. Dual Fire.

But, the later model module works pretty good. I never used a screamin' eagle version with mine. I did run a later version at one time. Finally, after messing with the wiring long enough, I ended up replacin' the whole mess with a single-fire unit from Ultima. The whole thing fits in the cone (except for the coils of course) Love it, easy to install, easy to adjust, runs good, can set the rev-limiter higher, change the advance curve, etc. And if you really want a dual-fire, it can run in that mode too...

The exhaust could also warrant its own thread. I've never used a slip-on with mine either. Went from "true duals" to a 2-into-1 and love it. I noticed more low-end power as soon as I installed it. Again, using the "Seat of the pants" dyno. If you want quiet, you might have to work on something for sound. Mine's pretty loud when I really get on it.

Just a bit of my experience and opinion. Good luck!

As already mentioned, when/if the heads are pulled, a precision valve job, and .060"(up to .080") removed from the cylinder head gasket surface, and the increased power delivery will be well worth the effort.
You would experience an increase in fuel economy as well, and lastly, you will also notice smoother running.
Rock-solid combo that lasts for years.

I'll be to the point:
Dyna 2000i ignition
CV carb is ABSOLUTELY fine.
Either a Wood 6, or Andrews 27.
NGK Iridiums work good.
Re-surface the heads, -.060" min.
IF you do this combination as decribed, you will experience the fun you are looking for, as we have replicated this combination 75-100 times over the years. The results are always the same. Good.

I'll 2nd that. Was the standard build when it was just Evo's out there. Can't go wrong with that setup.
