Ever notice how sometimes you can get one major part to a bike, and from
there the wheels just never stop turning? That's what happened to me when I
discovered a reproduction small coffin tank in the "For Sale" section of the
Maicomadness page.![]()
I thought the tank would look great on my 79 250, then when received it in
the mail, and really began to look at it, I began to reminisce about the 1975
Unadilla Trans-Am I attended in 1975. It was the first pro race I had ever
attended. Of all the bikes that were there, and we are talking the "hay day"
of European bikes, the one that always stayed in my mind long after the race,
was Adolph Weils GP 400. For some reason, that highly polished tank and the
beautiful noise that came from that machine never left my thoughts. "Wish I
had one of those" I thought to myself as I stared narcistically at my
reflection in the new tank. Then it hit me! "Why not just make a replica of
that bike?" I had purchased a 1978 400 Magnum for $250.00 about a year
before. It needed to be completely restored, but with enough vintage bikes,
and two evolution bikes already complete and ready to go, I just couldn't
give myself a good reason to get started on it. This tank gave me the reason.
In the fall of 2000, I stripped everything from the bike. After a closer look
at things, I realized this bike didn't shift either, but more about that
later. I stripped the paint off the frame and swingarm, primed it with![]()
Vari-Prime etching primer and painted it the same color silver as the mid
70's Maico's. I used a single stage paint by Dupont. Now with that done, and
the cold weather coming in, I could concentrate on the mechanical end of this
project. As mentioned earlier, the bike didn't shift. Actually, the shift
moved very freely, due to the fact that the shift shaft was snapped in half
inside the case. I didn't know this was the problem until I removed the
engine, then promptly found the shift lever along with a 2 inch piece of the
shaft in my hand. After removing the primary side cover, two of my senses
immediately went to good use. Sight, when I saw the amount of metal floating
around in the remainder of the fluid, and smell, when the aroma of burnt oil
eminated from inside the engine. This bike obviously went through an abusive
period sometime in its life. I'm not going to bore you all with another Maico
clutch story, but it was the first one I had ever taken apart. I'm sure you
all remember the first time you did it. Hard to understand how 18 or 20
(depending on who you ask) cupped washers can make one of these clutches work
until you take one apart. Easy to understand now why every Maico rider has
the left forearm of Arnold Schwartzeneggar. Upon further dissection of the
engine, I discovered a few broken gears, which I replaced along with the
shift shaft, a bent layshaft and a hooked "T" ratchet. (Yeah boys..I know
all the terms now). As with all the bikes I restore, a fresh top end was
installed as well. I found a Mahle piston brand new on E-bay for only $145.00,
about $100.00 less than many of the dealers who have them charge. After
looking at as many pictures I could find, I began the process of making my
bike look as close to a pre-75 bike as I could. This included bead blasting
the cylinder, choosing the correct fenders, adding fork boots and tank
decals, which are AW replica decals, but I really like them . For a little
color contrast I went with blue Terry cables. I then added Magura levers, new
seat cover, bars, grips, Metzler tires, Side Winder self cleaning sprockets,
gold D.I.D chain and a nice set of Akront gold anodized rims. I also had the
cylinder ported as well. Then came the pipe. "Got to have a down pipe on
here" I thought to myself. Well the good news is a 77 400 down pipe will
work. As you can see, the only thing you have to do is figure out a way to
attach it to the frame. I didn't want to weld anything to it, in the event I
should decide to restore it back to its original form. So with some aluminum
plate I had, I made what you see in the picture. The bad news is, you can't
ride the bike. The pipe just doesn't tuck in enough under the frame. If your
going to build one of these bikes to look at, fine. If your going to ride it,
which I have done, DO NOT put one of these pipes on your bike. By the time![]()
you read this, the bike will have a Wheelsmith up- pipe and silencer on it. I
made the brake pedal too. This pedal, unlike the pipe, is not going to be
effected the next time you go through a whoop section or come up short on a
jump. Well, there you have it. It's really more cosmetics than anything else,
but it was alot of fun to do, and it gets all the looks at the track. The
bike runs beautifully, is quite fast an so far seems to be a reliable ride.
This was all because I bought a tank. I could only imagine what I would have
gotten myself into had I ran across one of the "jack shaft" swingarms from
Gaylon Mosiers old Wheelsmith bikes. Remember those? In closing, I would
like to thank the following people for their support, advise and
encouragement:Eric Cook and Dean Collie from Maico Only, Rick and John at NW
Maico CZ, my friends and race buddies, Ed Shaffer, Mark Wunderlien, Scott
Campbell, Ted Bolkema and of course Bob at Maicomadness for giving us all a
place to show our handy work and find all the parts we need to keep our
Maico's moving.Joe Abbate
