Dunstall Replicas - 1971 OIF T120R

[speedrattle]

these are tarazzi universals. adjustable with a vernier mechanism. there are lots of similar ones available, but all will not clear a kickstart. even with these in the passenger peg mounts, your heel will hit the shift lever. a loop over the peg for the gearshift (like the clubmans) works better, but is a bit fussy. ive seen other units from the 60s that were built that way.

i use tarozzis on the other machine. i have a phot somewhere maybe.

dime city cycles in america usually has a selection of simple ones. then theres barleycorn in the uk

Ohhh... those Tarozzis are very nice... and they make them foldable, which I assume is necessary with the Bonny's kickstarter... (I'm highjacking my own muffler thread...)

Well, winter has settled in and I've done precious little toward settling the exhaust question. But I did want to share this link to an extended jaunt across the English countryside aboard an OIF Bonny T120R with stock silencers.

My bike would have more intake noise with the K&Ns I've fitted in place of the OEM air box (packed away for future sale), but this gives a good sense of the volume and timbre of the stock cans at a variety of speeds...

dont sell the airbox. youre going to die someday and your family will get more money if the machine comes with all the stuff you changed. doesnt matter if the changes are improvements, the high-dollar buyers will want to return it back to stock.

every one of my machines has with a wooden box containing everything i took off that can be conceivably be fixed or re-used-- outdated, worn-out, broken . . . i still have the airbox off my 72, and its been in the box for almost forty years

Well, first of all, I will never die. I'm working on a new novel (sci-fi) involving an innovative method of staying alive long enough for interstellar travel, and it's pretty cool, so just maybe...

Second, and in all seriousness - thank you. I've got the signals, grab rail, taillight, and airbox in a carton, and I'll do what you suggest. Indeed, that's why I didn't seal up the holes in the fender for the OEM breather hose, even though I loath how it looks, so changed it out for my purposes.

Exactly!

I enjoyed F. Herbert's novel a great deal (which neither of the movie versions can come close to matching), but my story involves a very different method which... Well, no spoilers. But suffice to say I'm writing the middle book first in what will be a trilogy. I've borrowed the title for book two (can't copyright titles), which is "The Hinge of Fate."

But I digress. I am s-l-o-w-l-y rebuilding the speedo on my '51 Harley FL as the cops like to set up speed traps on the two-lane blacktop that leads up from the Rio Grande to my ranchito, and I've just got to have a running bike at all times to maintain my sanity. (I will ride an un-faired motorcycle anytime it gets up to 50 F.) But hope to dive back into this build in the not-too-distant future. My apologies for the interim silence.

Happy Holidays, everyone - and here's a virtual Christmas card, taken from my entry courtyard not long ago...

Cool. All I ever wrote was the Old Bikes book which only old guys with old bikes will ever like.

Wowza! A couple of (thousand) times nicer than our view from the front door of the "ranchito"...

Well, where could one get a copy? Though it's way off topic, my first novel, "Lion at the Door," is on Scamazon. It's about a former POW and FBI profiler who's put in charge of the first Homeland Security office in NYC in the wake of 9/11.

Personally, I believe there's singular beauty in virtually every rural American landscape. In fact, I paused "Hinge" earlier this year because I was inexplicably inspired to write a story about the 25-year-old granddaughter of the owner of a century-old Texas Hill Country horse and feed ranch. She's coming home on the occasion of her mother's untimely death from breast cancer, and she rediscovers her connections to the land, her childhood memories, and to her aging grandfather--plus there's a mystery woven in... It's called "Los Dolores" and will probably only appeal to old sentimental types like me. But I don't care; I'm writing it anyway.

Good luck with your books. Interstellar flight most people think is just sailing around the stars without ever thinking about the actual distances involved. Considering that it takes a single photon traveling at the speed of light 25,000 Earth years to go from one end of our galaxy to the opposite end your methodology had better be unique. Einstein deduced that matter (anything with mass) cannot achieve the speed of light so innovative it must be. Like I said, good luck.

Unless, of course, your name happens to be Dr Who.

I’m intrigued by the oil tank/tool box space under the front of the seat. I ask because when I resurrect my Tbird I am contemplating something similar. Please tell me more.

Actually it's unless you have a Tardis.....

But only Dr Who and maybe his current companion/s will have keys to gain access. Once inside only the Doctor knows how to navigate/drive/fly the thing.

BTW, there's more general stuff on the other thread dedicated to restoring and modifying this bike (same forum). But to answer your question, the way I bent up the side covers didn't contemplate containing the air cleaners--though it could have. They're just external and kind of boring as seen below. I was looking for a lighter, simpler departure from the OEM cast airbox--though, as I type these words, I realize that I could make a nifty CNC-machined, 6061 clamshell one-piece unit that would take a K&N panel or oval filter. Hmmm...

Since this is an OIF model, and the covers arc more or less straight back from bosses welded to the backbone/oil tank--and because I kept their height modest for aesthetic considerations--there isn't a ton of room in there. I'm running a Boyer Bransden ignition (came on the bike), but a 3-phase alternator managed by a vintage Honda rectifier that hangs aft of the battery from an aluminum L bracket bolted to the underside of the OEM twin coil mount.

The ignition switch position and heavier gauge leads, a la stock (2nd pic), takes up the scant room under the tool tray--which I'll probably duplicate in aluminum left over from the covers (not yet polished and striped here).

Well, of course my solution--dreamed up by a modern day, climate change-driven, top secret team akin to the Manhattan Project vis-a-vis the bomb in an earlier epoch--is inextricably interwoven with a key aspect of the plot... so you ain't gettin' it out of me.

I briefly considered making the protagonist of "Lion at the Door" into our hero once again--but it's just too much of a stretch, and Agent Gaines is probably going to be in the wind in northern NM, fleeing his old employer, in a much-requested sequel to "Lion" anyhow, so...

And that was often questionable, but it always took him where he needed to be.

Don’t know if you guys are up to date but I’m eagerly awaiting the Christmas Day special. Am gradually ploughing my way through the behind the scenes Confidential episodes.
