Thanks, SDaniels.

We all have to be careful not to get caught up in justifying some mod with psycho-babel just because we bought into it.  The only thing we might get out of loud pipes and hissing air cleaners is more noise.  It is easy to deceive ourselves that we also get more acceleration or speed than stock.  But the truth of the matter is none of us are racing our machines on the track where such mods might make a difference if a run on a dyno suggests it.  And I have yet to see a Bolt even do a wheelie, though I suppose someone somewhere may be.

Wheelies are out...OUT! Shorter-reach handle bars are in. Ivan's Flash is inI really don't like the jerky throttle, not at all, particularly for very slow maneuvering exercises. Vance & Hines Twin Slash Staggard...in, but not now (I like the sleeker look; fits more into the my bike's personality, but that's really all they'd be for).

Oh, and I do need saddle bags (tired of carrying a backpack just to go get a few things at the store).

Otherwise, I'm good.

To each his own.  I only take issue with the notion that the throttle is jerky.  What it is is sensitive, and it only needs a touch to accelerate strongly. I suspect the villain in the throttle is the rider who has allowed too much play in it, and hasn't learned the secret of the gentle nudge.

The Twin exhaust is good for sound and looks. For performance and light weight a slip-on is the way to go.

Lunkhead,

Im just learning about the slip-ons. Are you referring to a slip-on over the stock exhaust or over the Twin? Sorry, I'm reading my bottom off to try to get up to speed!

So 99% of Bolt riders on the board agree about the jerky throttle but it's the rider.  Gotcha.  When he gets his ecu flashed, he'll be very happy he did...like you said, to each his own.

Starkman, slipons refer to replacing just the muffler on bikes.  You keep the headers.

@ Sdaniels: You making up your own facts?  So far I've only heard you complain about "jerky" throttle.  Haven't heard from the other 99% you claim.

Look at the dyno charts Ivan's website.  There're comparisons for different configurations run at full throttle. Decide if the drawbacks of an open filter are worth trouble. If you're never at full throttle with the stock airbox, you're already making all the power you need.

See, I tried to be clear that I'm not after power and performance as much as I am a more efficient ECU system (and, as mentioned, the elimination of the jerky throttle).
Drawbacks of an open filter? I didn't know I had to have an open filter (presumably, if I get the Flash).

As I also noted, I'll be calling Ivan tomorrow morning, and I'll try to get all the information then.

Thanks very much, all.

Ivan's first version of the flash is what he might offer for the stock airbox. The second version adds fuel up top for running an open filter. With the stock airbox and ECU, you can get more power by adding a Power Commander 5 fuel controller to lean it out. The stock Bolt runs rich which is not necessarily a bad thing for an air-cooled bike. I run the airbox, a slip-on and Ivan's first flash with no complaints. The jerky feel is gone and the ignition timing is advanced (runs cooler, more efficient, pollutes a little more) which are all I really cared about. I did make an attempt to get it running a bit leaner than stock by modding the airbox but that's just me not leaving well enough alone.

Starkman, in my reply A/C meant (aftermarket air cleaner, Hi flow). Lunkhead has it exactly right IMO +1. I have V&H slip on (lighter, more performance), Kury Velociraptor air cleaner (looks, performance), Ivan's flash (eliminates all quirky running issues per his list of benefits(website). I too have had no running issues since flash, if you do nothing else do the flash! The slip on uses stock header pipes just replacing muffler portion if you are still looking for clarification on that. View my profile for pics and mods.

I experience jerky throttle when rolling off the throttle and back on.  For me it's most noticeable when riding slow through a parking lot.  I've had my bike for about 3 years now so I can live w/ it and being smooth with the throttle helps but would it be nice if that jerkiness was gone?  Definitely.

Starkman:
If you look at Ivan's charts, you'll see that there are NO Exhaust systems that are really much of an improvement over the stock exhaust. Mamma Yamma actually did an EXCELLENT job at designing the exhaust for airflow, and met all legal requirements for noise.  So if you like the sound and look, don't change it!   You might get ribbed for the Whiffle-Bat, but don't take it seriously...  It's what YOU LIKE, NOT what anyone ELSE likes that matters!

I have the Twin Slash, and originally found it WAY too loud (I got complaints from Hardley Drivers with open pipes that my bike was TOO LOUD! :o). I was setting off car alarms as I IDLED past them.....   I quickly got a set of baffles and found I liked it MUCH more. 

As for performance - IVAN'S is your first choice.  NOTHING ELSE does what the Flash does - especially getting rid of that On/Off switch feel of the stock setup, and most , if not all of the Popping on Decel, which you really can't hear with the stock exhaust, anyway.

Otherwise, If the air intake bothers you, there's lots of choices for smaller setups, most of which will work really well with Ivan's flash, but there's both flashy and plain types if you're interested. 

The big thing is to make it what YOU want, and everybody else can go to H*ll........   ;D

Well four people acknowledged it within a couple of hours of your post, so there is that.  Ninety-nine percent is an obvious exaggeration but did you really expect everybody to respond immediately to the claim?  A search will verify the jerkiness.
