exhausting thoughts

[the draggin]

I'm anticipating going over to tru-duals on my FLHTC since the crossover cracked-up. Question is, will I have to mess with the fuel injection settings?
I already have SE mufflers and air cleaner and an EV23 cam. yes no maybe?

If you use the S.E. mufflers with the true dual headpipes you shouldn't need to change anything. True duals look cool but I really don't think they will make much difference in performance. Probably a little more on top and a little less mid range but probably not enough to notice. That balance pipe is there for a reason. Bub, I think, is offering a true dual system with a balance pipe, go figure.

Thanks, I had't seen that "bub" set I'll keep looking.

Hey draggin
I can't see where the switch to tru-duals (with the same mufflers,etc) would effect things to the point of having to readjusting your EFI...anymore than they would require a carb equipped bike to be readjusted. This past Spring I helped a friend replace his stock-pipes with V&H tru-duals (keeping the same Kerker mufflers) when his cross-over (rewelded once) cracked again..and he's had no ill-effects with the EFI on his OR any noticable gains..although I've got to wonder if a good EFI tuner (over MY head) could'nt get some more out of it wherever in the power band.

Then again it might be worth noting that his bike is a TC..running an Andrews 37-G cams that're closer to the spec.s of an EV-27 than your EV-23. So maybe I'm comparing apples to oranges here !?!

Now,as for a "balance-pipe" ?? Uhh,well,according to what I've heard/read I think the jury's still out on that one..other than figuring one of those may relieve a little back-pressure (between pipes/pulses) at higher rpm on some systems,when running restrictive mufflers..with maybe a little scavenging going on there. That and I for one would'nt think of a cross-over pipe as a balance pipe..because it really only effects the R. exhaust pipe..and way ahead of where the F&R pipes join together on the one side.

Thanks Evo, I just was at the shop and I can't make up my mind on which pipes V&H seem to be the winners so far. going to the cams thread got more stuff.

There is a reason I didn't join this thread before,,, I haven't done what you're asking about and neither have the other guys---

You gotta lota guessing and supposing but so far you got no good info..
Why is that..??

Until somebody checks in that actually has hands-on experience with what you're asking and offers some real advice, you should at least have the A/F checked-out afterwards.. And, just because a guy that does have experience says it should be ok, that doesn't mean it is..
If you don't have actual symptoms that tell you something is needing a new adjustment, perhaps you should at least have it checked out after you make whatever change you decide on..

Ken-- I know,, you're going to say you do have some experience with it cuz you helped your bud change over his exhaust but you admitted that you don't know if it needed any follow up adjustments.. Just exchanging one thing for another without the experience of "making it correct" does not equal experience..

O-six
Back-up your statements of he ....."shouldn't need to change anything" and
""Probably a little more on top and a little less mid range but probably not enough to notice."" WHAT???? Yeah that's real good advice...!!!
Do you really know those things or are you just guessing.?

Let me give alittle basis for my irritability today..
99% of what I offer to folks is from actual Hands-on First-Hand experience..
There's no excuse for anything less.. Facts and First-Hand experience trump opinion everyday..

[the draggin]

Frisco since you seem to have the experience and I don't can you help answer another question? Are there diferent injectors available for the Evo that can juice it up a bit?

[frisco-rigid]

I would have also passed on this question about your injectors cuz I have no experience with them either..
But at least we now know that your sickle is a '95 to '99..

There are some very savvy guys here that do have the First-hand knowledge you need about the injectors for your sickle.. They'll check in eventually..
When they do they'll offer their results and the changes needed for you to have the same approximate results.. You won't have to wonder where they got their info..

[the draggin]

Thanks Frisco I appreciate you input and honesty.

Yes there are bigger inj. they were included in the stage 2 kit that harley sold. My first hand experience is that they work real good with an EV27 cam, K&N filter and cycle shack exhaust. Anything I post is from experience. That means doing the work myself in my garage Frisco. I don't know what your problem is Frisco but I'm just trying to help the guy a little, we aint splittin atoms here. A power commander and a custom map will make the whole setup work better but dyno time aint cheap, I spent 500 on the custom map I had, it was a really strong 80 inch evo though. You could have a dealer install the stage 2 map for a lot less money and the bike would run fine, perhaps not make as much hp but I doubt that you would notice the difference and it aint a race bike anyway, right?
