The Dead Rat
1967 BSA A650T Thunderbolt heart in Frankenstein's body.
This is Griz's personal ride. The idea was to build a bike for him and only for him. Therefore, the bike is super long (over 8ft.), super slim (look at that pic of the back!), and just a little scary.
This is
what they looked like from the factory. 650cc parallel twin rated at about
49 horse. The Thunderbolt was the economy model from BSA (Birmingham Small
Arms makers of fine rifles and such) as it only had one carb. The
Lightning was basically the same bike (different seat, etc.) but had the dual
carbs and a little more punch. Personally, I hate adjusting the things, so
one is enough for my bike!
This
is what rolled out of the truck the day it came home from St. Louis. The
bike was purchased from a guy that was selling (and still is to my knowledge) a
ton of old British iron on eBay. The bike came with a small box of parts
(including a sweet little Mity Max unit and not much else) and no history
whatsoever.
The
bike had a certain coolness as it sat, but it was not what I wanted for my
bike. Almost everything was replaced. All that survived was the
power plant, carb, and rear wheel assy.
Well,
there's the tank and the seat just sitting on the bike. I still really
love that beat old high back seat, but it just didn't work on this bike in the
end. The coffin tank is what gives this bike its name. It was
another eBay purchase and there was something rattling around inside when it
arrived. The rattle was a really dried up dead mouse all twisted up and
stuff. Kinda gross. I always thought rust was hard to get out of the
inside of a tank, but it has nothing on dead mouse fur. So, the name was
born. The hope was that the name wouldn't describe the engine as well!
I
got a little bored with a paint program and was messing around with a
concept. This is what happened. Eh.

Duct tape is a wonderful thing. This pic is actually quite a jump from the last one. We took off the old fatbob tanks and got the oil tank and coffin tank on (well, in place anyway). The whole reason for this was to see if the thing even ran. It did. We didn't even mess with the old points ignition and installed a sweet little Boyer black box. A couple of kicks and that baby fired up like a race car. It's just crazy loud without any mufflers and has just amazing throttle response.
You
can see the Boyer unit in this one as well as the well oiled instructions.
Also, check out that headlamp unit! It's a real Lucas, but has nice non-British
bulbs in it. BTW, thanks to Fred for welding the hell out of the kicker
after I broke it (it was almost done for when it came in). Also thanks to
Matt for helping wire and kick for a whole day! The headers were a new
purchase from Baxter Cycle down in Marne, IA. Their stuff is expensive,
but worth it.
Yeah,
well I never did like that other frame anyway! Well, I did, but this one
works better for me. The boys at the Wilson's Body Shop put some nice
black paint on it for a dirt cheap price and the molds are all done up '70s
style. There's a picture of the Springer too! Yet another eBay
purchase with an unknown history. I've found others like it saying they
were a D&D brand from the '70s. It's super long and the chrome on the
front legs is still good. Eventually the back legs with get a powdercoat
in black.
This
is where we sit now. One mean freakin' bike. The bars are from
Hackasaw and sit in dog bones attached to a nice little top clamp with ears on
the Springer. The front wheel is a 19" spool off some little ricer MX
bike or something from Baxter Cycle with nice new Maxxis rubber on it.
Both lamps are wired to be on at the same time (it would really look stupid with
only one bulb on going down the street!).
That
godawful oil tank is gone replaced with a cool old hexagonal aluminum
unit. The battery eliminator is also gone as the stator couldn't keep up
with the demands of the Boyer and the lights at the same time. Maybe the
future will bring me one of those cool high amp stators. Just look at that
sissy bar sitting way back there! I think it lends just the right swooped
back look for the bike. As I said before, the 16" hog wheel on the
BSA hub (left side drive and drum brake on that thing give this bike that open
right side that people are spending a fortune for on their Harleys!) and the
motor are the only parts that have been saved from the original setup.
Here's
a good shot of the new seat with its cool brass buttons just like in the old
school! The kickstand will get repositioned so I don't have to carry a 2X4
with me everywhere I ride. After that, all we have left is some paint and
some more riding! Maybe some forward controls... This bike will
never be really done.

I just love this picture!

Now that just kicks! I wasn't really planning on it, but the time came to paint up the tank on the ol' Dead Rat. I got the serious hook up from my buddy Adam at work. His skills are just amazing and this turned out really well.

On the side you can see the really sweet devil tail flames that Adam laid out for me. Basically, I wanted to keep the bike monochromatic so I asked for something in black and white with some flair. Adam came up with this design and those sweet tails on his own. Obviously, the tank is gloss black with white panels, but the flames are done in a white diamond pearl. He will definitely do more of my stuff in the future!

Just really super impressed with the job he did. It was short notice too! I think the bike will be taking on a more "finished" look very soon. If you have something that requires Adam's expertise, contact him at: paint@grizzlychopper.com
Well,
we dragged the bike out to Colorado so the family could see it and everything
went really well! We snapped some shots while out there and this basically
represents a finished bike. Some chrome and finishing touches later and
this bike will be ready to tear down and start over!



Comin'
at you LIVE! The Dead Rat, everything a chopper should be and nothing it
shouldn't!
