A very special welcome to you, Ivan Grozny! I too have a 2005 "Military," though with nothing so grand as that Hitchcock's big bore kit installed. What follows is the lowdown on mine, which may or may not help you get your own better fettled...
A previous owner had been kind enough to install an electronic ignition, for which I'm grateful for ease of maintenance and reliability's sake. I
removed that sillyass crankcase breather catch can system which had been clogging up and causing real problems. I also put in a full-sized 7" headlamp with a
natty little cap instead of the goofy little 5 3/4" DOT-mandated one, and also
yanked out that wiring "dogbone" in the headlamp shell that bypassed that perfectly good lighting switch, keeping the headlamp always on (another DOT mandated goofiness). The sprung rider and pillion saddles must have been added by a previous owner, along with a handy loop handle attached atop the lefthand shock to more easily hoist the beast up onto her centerstand. I found another matching handle in the parts bin given to me by the previous owner, and stuck that on too, onto the righthand side, figuring I might be able to then use both handles' loops to securely strap gear down onto the pillion saddle when touring. I also slapped on an
ultra-cheapo $16.99 sidestand from India, which is holding up remarkably well...keeps me from having to do the full heave-ho every damned time I stop, especially on that hill by my boats' storage lot gate. That whole "Grunt!--[Open Gate]--Grunt!--[Close Gate]--Grunt!" routine got old quick. One other super-useful addition has been an inexpensive little waterproof
combination 12V USB & Cigarette Lighter Power Socket doodad that I've snuck onto the frame under the rider saddle, though it would fit nicely onto one's handlebars too. I use my phone's Google Maps "Route Options: Avoid Highways" trick and some Bluetooth earbuds for touring, so keeping that gear powered up is sort of "Mission Critical." Also, chicks dig USB ports.
Other than that lot, as far as I know everything else on my 2005's probably bone stock, including the exhaust system. I've still got that preposterously long original "Bengal Bottle" silencer/muffler, which I rather like the almost bizarre length and look of, and also the "pulse air" system with its inlet doodad welded into my downpipe/header near the exhaust outlet. I'm led to understand that this pulse air system (its controller's under the lefthand sidepanel) is intended to let a bit of fresh air into the escaping exhaust to help burn off any residual unburnt fuel when it reaches a kind of not-quite-a-catalytic-converter doodad that's usually sort of tap-welded into the muffler end of the downpipe, or in some cases within the muffler itself. I'd imagine all of this restrictive power-sapping and sort of heavy emissions crap would have been long since removed by any previous owner savvy and eager enough for added performance to be lobbing in a fairly expensive big bore kit from Hitchcocks. I'm perfectly OK with mine being there for now, since it keeps the roar to a minimum when I kick the beast to life. Like I've said here before, I have neighbors I like on both sides with small children and I don't want to be "that guy" rousting those kids from their naptimes just as Mom's breaking out the Chardonnay for a little "Me Time." Maybe in several years I'll do the whole "Performance Upgraydd Thang," but for now I'm pretty content just
thumping along backroads in the 50s as I do. It's powerful and fast enough for the geezin' likes of me.
I can tell you that you were told right that this is the Forum to be on to help get your Enfield squared away. I got mine last December, and she was ailing too. Thanks largely to the clever and helpful folks here, I'm now pretty confident I could hop on her, go most anywhere, and my ass would wear out before that bike.
