1984 900 Ninja restoration project
« on: November 20, 2011, 08:46:00 pm »
Well we are just starting another winter project, (last winter was a ZL900 Eliminator).
We just found a 1984 ZX900a Ninja with 4200 miles on the odo.
It has been down on the left side then parked for about 20 years.  :o

So we are starting to disassembly and clean things. most of the fairings have issues and the gas tank is full of rust. 
It looks like the carbs have been removed and cleaned. I will check those out and re-install them!!!
The motor turns over by hand, so we will check for hydrolock next, then drop the oil pan to check out the strainer and pan.

Anyone got any old parts hanging around the garage???

Oh I know it doesn't exist with out pics so :

I wanted to do a first year Interceptor or Ninja myself. I couldn't find anything decent that was somewhat close. I almost picked up a Ninja from Missouri, but decided it was a little too far. Then my 86 Concours fell into my lap. That was a fun project that turned out pretty good. Although I keep finding things I can do on it. The thing that sucks, is once it's done, then what. You don't want to ride it too much and rack up too many miles. But you hate looking at it sitting too much also. Decisions, decisions.  8)

I love that first year Ninja.  I remember wanting one and not having enough money to buy air for the tires.

This sight might help in finding parts. I have nothign to do with it but there is someone from Southern Utah who collects and rebuilds old Ninja's.  Many times he puts up extra parts here.  http://www.ksl.com/index.php?nid=231&cat=464

So we are thinking of painting it Kawasaki Green with white on the side of the tank.
Similar to the way the tank is done on the bike currently

My son paints cars at a custom shop, so if I give him all winter he gets some great stuff done.
See the pictures of our Mean Streak we did recently.

I have an easy fix for the gas tank.  Gas and a match!  :-\  Man that thing is rusty! Best of luck with the restoration!

The inside of your gas tank looks like mine from my 86 Connie.  I soaked it in white vinegar for 2 weeks which removed a lot of gunk. Then some large ball bearings, an old bed blanket and into the clothes dryer for a couple of hours (on air dry).  It made a tight fit into the dryer but thats what I wanted so it wouldn't damage the dryer (but I didn't tell the wife).

I then lined the tank with this stuff: http://www.caswellcanada.ca/shop/epoxy-gas-tank-sealer.html

No need to etch the inside of the tank, this stuff works great, it will even seal pin holes.  There's about a 1/4" of coating inside the tank.  One drawback is the coating adds about 4 lbs of weight to the tank.

Nope, not exaggerating.  I put a real heavy coat on the inside of the tank.  The kit is for two tanks but I used it all - it ain't gonna leak !!

eh... Not sure about this case but often with coatings you don't want too much thickness as it could lead to cracking or other problems.

I used the same stuff on my old Harley Shovelhead 4 years ago and its working good.  I did try Kreem but it eventually peeled off.

I used Kreem on this on 3 years ago after it was painted. That was a challenge!!

1984 900 Ninja restoration starts
« Reply #11 on: November 28, 2011, 08:28:17 pm »

Well Today I removed the emission stuff from the valve cover (ordering Snarf's block off plates)'
Checked the valves clearances and R and R'ed the valve cover.
Installed the stick coils from a C-14 with my own custom harness.

Carbs look like they have been done but that is the next thing to check out..

Friday is the day off work, Until then ;D

Revival of thread!

OK the tank has been at the "shop" for months. He will finish it this month

So I took the forks apart and cleaned and resealed the forks, and the carbs have been Ultrasonic cleaned and rebuilt

New brake pads and re-finished the front wheel. Look for more updates soon

You will want to check the cylinders also.The center 2 sleeves on that year on about 6% of the bikes would slip and drop 2mm or more causing the head gasket to blow.You will be able to tell immediately as it will be blowing a LOT of white smoke when it's running.Just a heads up. ;D

Thanks for the heads-up on that issue.
I added C-10 handle bars from an 86 model and i'm installing a switch to run the cooling fan independent of the factory sensors.
Start cooling it off before it gets HOT!
