The first iteration of this website appeared in late 2014.
I had an '82 chain-drive and wanted to go fast.
I looked around and there was nothing designed for these bikes.
I saw that Viragos are almosat identical internally and decided to branch out.
I looked around. Pistons were made to order and cost as much as a thousand a pair.
And they weren't shaped right for real power.
Cams were a little better, but the specifications were too short and too low.
I pulled together some cash and created Big twins LLC.
Acquiring all the documents took some work and some visits to city hall and the tax board.
I sent thick slabs of documents to every vendor and manufacturer I could think of.
Most wanted me to send them pictures of my store; inside and out.
My inventory is on racks out in the driveway under a tarp.
Needless to say, most vendors gave me a pass.
I did take a buch of pictures of a friend's dyno room and work area for limited distribution.
As a result, I believe that I am the only one-man merchant for ProCharger, Athena USA, and some automotive concerns.
I drew sketches and made molds. I sent pistons and rods out. I calculated airflow against cam timing and lift.
I got some good responses. Business grew and I found that most of my sales were overseas.
For the TR1, a motorcycle I have never seen. But airflow is airflow; the calculus is the same.
A year or so ago, my piston supplier was absorbed by another concern.
Suddenly I had to tell people that I lacked the heart of high performance and sales disappeared.
I approached some manufactureres and told them I had no store,
but I sold all over the world and dared them to supply me.
Two took me up. Working from samples of stock and modified pistons, they offered their products.
Two years ago piston kits were five hundred dollars a pair. Now the cheapest is almost seven.
Business has restarted, but slowly. Where I was selling two to four sets a week,
I now see a set a month. It astonishes me. There are many bikes that are in my realm.
I am the only source for specially designed goods on the planet for these bikes.
This is a last refuge for those seeking performance for their '80s vintage XV series bikes.
The site bigtwins.org provides what knowledge that I am able to produce on a as-time-is-available basis.
Clicking the yellow title at the top of each page takes you back to the landing page;
clicking the banner there takes you to the information site, as does clicking either of the enngine logos.
If a page has a subtitle, clicking that refreshes the page and probably will bring up a new background.
I toy with a login feature, but frankly see no need for it.
I have a small program that tells me the local time and location of each visitor.
I noticed that about half the visits were from China.
No version of the Virago was sold there. I added to the location program
and if the visitor is from China, they are presented with an error page and denied entry.
Maybe this is overly paranoid. But what are they looking for?
I probed performance parts for the mega-cruisers: the XV1900, the M109R, and the Thunderbird Storm.
Indian and Victory are well covered by Lloydz.
The site gets many visitors, but I have yet to get any queries.
The major problem is that every Double Liter twin needs portwork to perk it up.
This is _very_ expensive and labor-intensive both for the portsmith and the mechanic (usually not the bike's owner).
I suppose that stock power is enough for the riders.
What can I say? I like to have power from idle up past redline.
A ten second twin is a real kick in the pants and a true fooler for the competition on their hyperbikes.
Since I don't have a physical walk-in store most distributors will not deal with me.
A few will; click the "Vendors" link on the start page to see some of them.
A lot of manufacturers aren't interested in supporting rare, obsolete series -
especially in small lot quantities.
There are a number of mfg that don't deal directly with merchants; distributors only.
There are also mfg and/or distributors that don't like to have their products
sold at too many places. They tend to feel that certain areas are sufficiently "saturated."
Every year; every model is a bit different. Exhausts are no longer made.
There are some still sitting in warehouses that get sold off in batches at pennies on the dollar.
I pass these up as I lack space to store them and every year is different;
and more importantly: most of these exhausts are quite loud and designed for boulevard cruisers.
Not a good fit with our philosophy of what a sporting twin should be.
One that I wish I could help with is cables.
The best source I know of is Motion Pro. I am in Orange County and Southern California
is saturated with their merchants. Again, every year, every model is different.
I leave it to the customer to send measurements and particulars to them.
Expect about fifty dollars per cable. Our VM, TM, and HSR series Mikuni carbs all use different fittings.
As do Keihin FCRs. Before I forget: please do not run 1) a
single carb manifold, 2) Bing, or
3) Dellorto carbs. These last two are using twenty plus year old technology.
