Big-E.

It's going to make mine look like an old rust bucket, Steve the powder coating guy wanted to do my 490 at the same time, but I didn't want to have 2 490's taken apart in my garage at the same time, you know what I mean it could get real confusing who's parts went where?

Howard.....

That is one awesome project you've got going there! I am impressed. Wonder what the sell price was on that ride!?

You will have it ready for your client by the March EVO opener?

I ran into Jake DeBoe at Rio yesterday and he thinks he has one of these for me: http://www.motocrossactionmag.com/Me...ky%20125cr.jpg

Ok so I've had a few ask me where the rest of the Maico build is?

Well it's been rough, as we are still waiting on a few parts & had to have some motor work done that I can't do, like bore the cylinder & fit the piston.

But it seems as soon as I attempt to do something like mount the front tire I find that the front rim is cracked, I told my fabricator about it & he said that he could weld it & it would be good to go.



If you look at the bottom of the pic you can see where it was fixed, it cracked right at the original weld.

Than I tried to removed the old rear tire, it had been in place since at least 1996! I couldn't get it off, so I had to take it over to my friend/Sponsor's shop The Holeshot in Humble & Patrick took care of it for me!


If you look at 12 o'clock you might notice a old time trick, yes it a sheet metal screw in the rim to help hold the Tire from slipping ( the old style rim locks didn't work very well)

I got the cases cleaned up too, I tried my friends portable soda blaster but could never get it to work, when I was at my fabricators ( Lone star metal werx) I used the shops glass bead cabinet to do the job.




You might ask why glass bead the cases, as they will just get dirty again. well there is a reason to do it on Maico cases as they are sand cast & I was looking for cracks & pin wholes that needed to be fixed before assembling the motor.

Didn't find any crack or pin wholes & the will be reassembled as soon as I get one wet side crank seal that Greg ( the owner of the bike) ordered about 2 weeks ago!

Got the pipe cleaned up & a base coat of paint on it, then we decided to buy a trick pipe for it, looks like the stock pipe will hit Evil-bay soon !


You see the shock holding up the pipe? It belongs to a friend that has also helped out in this project, looks like we are going to mount them for awhile, as Greg got a call from Works Performance basically telling him that his shocks that we sent in to be rebuilt weren't safe to rebuild for racing.

Just another little problem in the ongoing saga,

Hope to have the main seal by the weekend. Going to build the bottom end up to the wet side main seal, then it just add the primary gear & chains then the clutch.

I'm hoping to have it done by the 19th of this month, as our first Evo-Vintage race is on the 28th & I would like to get it broke in & setup for Greg who by the way has been very understanding of all the little delays & problems!

I'll update as I get more done!

Cool, I love these threads.

Keep up the good work.

That's pretty scary about the rear shocks. I guess that means they were pretty hammered.

Mike,

I haven't touched it, don't want to have 2 bike's in pieces at once.

I'm hoping to get Greg's bike done by mid week, If I can get that darn wet side main seal!

The joys of restoration work. These little gotchas can
really gum up the works. The rim crack at the weld is
a common problem. I have a brand new, never used
DID rim that is cracked at the weld -go figure.

The cases cleaned up pretty good. if you are concerned
about cracks or holes, I recommend an NDI, I do it on all
of my vintage parts. You would be amazed at how many
cracks I have found that weren't visable to the naked eye.
Here is a link to an inexpensive home kit:
Aircraft Tool Supply | MAGNAFLUX® PORTABLE SPOTCHECK KIT | SK416

Good luck with the rest of the build.

Getting close now!

Got a few more parts in & did a little work.


Most of the front end is done, just need to go over all the nuts, bolts & set up the front brake.

[IMG][/IMG]
Got the trick foot pegs mounted! Lost of grip on these baby's!


Mounted the shocks, rear wheel & side panels. I need to clean & install the new graphics on the side panel. need to order the tank graphics, as the set we ordered didn't look good at all, so I didn't mount them .
[IMG][/IMG]

Greg ( The owner of the 490) Ordered a set of trick torque pipes for both of our 490's!

Have to get motivated & get her done by mid week, So I can prep my 490 for the 1st race on the 28th.

Now all I need to do is remember how all these little parts make up a transmission that works? Got the engine seal in the the other day, jst need to put the engine back together.

Those forks look really nice. I rebuilt the ones on my 82 GS490 and they work OK, but would definitely be in the market for something better - what are yours and where did you get them?

As you can tell, I am more interested in having a kickn' off-road bike than having an authentic Maico. My bike is already kind of Frankensteined together. the engine is an 82 GS 490 but the frame is an 80 Mega MC400/T - hey, it works for me. Now if I could just get my Mikuni VM38 jetted properly.

Still, the nostalgia and all the looks I get are pretty cool, but in reality nobody but me would know the forks were couterfeit. So far nobody has noticed that I am running the wrong engine - or am I running the wrong frame?

I'm in central florida with a lot of big sand whoops and a lot of roots and I hated the stock fork. these are 49mm showas from a DRZ, you can use the same fork from the old RM250 also and it has better valving, I just wanted the newer forks with less wear, I can revalve them later. I also used the DRZ clamps, they are exactly the same as the stock maico clamps as far as offset etc, just had to get some shims machined and had to press the stock maico stem into the suzuki clamp. NO MAICO PARTS WERE ALTERED OR DAMAGED IN THIS MOD (:

here are the maico clamps compared to the DRZ:





here are the shims:

Ok I know it's been a while since I did a update on my progress, but I was waiting for a few parts.

Greg & I decided to get a different pipe, We both got a Maico Only torque pipe instead of the Wheelsmith pipe. I put mine on last week & I'll tell you that my 490 is a totally different Animal Man I thought that my 490 was fast before! But now it Leaps Hard out of the corners!

Another reason that I haven't posted a update is that for some reason that I couldn't figure out I couldn't get the transmission to shift threw all the gears, I could get it to go into 1st & 2nd, but it wouldn't shift into 3rd, 4th & 5th??

I took the trans apart at least five time's to see what the heck I did wrong? But I couldn't find anything wrong. So I have to call in my Maico mentor Ron King.

Ron went over my rebuild process & advised my to check the shift plate timing for proper alignment. I thought that I had done it right the first time, so I didn't bother to check it on the subsequent inspections. But I had the segment on tooth off on the shift plate causing me all the shifting problems.



I knew better & should have double checked myself, boy did Ron give me hell for that & I surely will continue to rightfully catch hell for it..... Thanks Ron for the Maico lesson!

After getting the transmission to shift I assembled the rest of the clutch & primary drive of the motor, after checking to make sure that the clutch plate were in spec.


From there it was a snap to finish the motor, now I just need to put it in the frame & install the ignition& carburetor.


I should have the 490 ready to fire up by Saturday After noon!

Nice work! I think you have more than likely forgotten more about a Maico than I know about dirtbikes in general.
