Won't you make my black Ninja blue?

Project: restore the original blue paint job of a 2007 Kawasaki Ninja 650r.

Plan: remove the flat black-out paint job and restore the original metallic blue

Backstory:

This '07 650r Ninja is my first bike, I got it a couple of months ago.  I was considering buying a new bike, but wanted something I could get mechanically familiar with.  I got this Ninja with low miles (still only 8k on the clock when I got it).  There was evidence it had been dropped, but the bike was in excellent mechanical condition and with the low mileage, it seemed like a good candidate for a restoration that would let me familiarize myself with motorcycle maintenance (I've owned many interesting cars, so I know my way around an engine bay).  

Making a black Ninja blue again

So far so good, the bike is letting me figure out the mechanics and maintenance, and works flawlessly otherwise.  The biggest effort has been trying to figure out how to strip the blacked out paint job and restore the body to the stock colour.  Here is the process to date:

How to Strip Paint Off a Motorcycle:

My first attempt was heavy handed,
but lessons learned on the front
fender paid off elsewhere

Stone chips were showing the blue paint underneath around the front fender, headlight and leading edges of the fairings.  With it looking so shabby anyway (it's not like it's a nice black paint job), I began with the front fender, trying to find ways to remove the black.

I tried wet sanding the black but this didn't prove very effective.  The compound curves on the body work ('07 Ninjas are very sinuous) make sanding smoothly difficult.  The sanding block would either burn through into the

blue below or damage the clear coat; it was too blunt an instrument.  I eventually tried some graffiti remover  and it did the job while preserving the factory paint.  

Once I got the technique down, the
black came off leaving the blue in
good shape underneath

I initially tried wiping off the sprayed on remover with painter's rags, but they are too smooth to work well with paint this thick.  I eventually tried tea towels with a rougher texture and they worked well with the Goof Off.  

Eventually I found that spraying a thick coat of remover on a spot on the tea towel and then wiping in small circles would remove the black paint leaving the blue underneath untouched.  This is best shown around the seat at the back of the bike.  Even the clearcoat was left intact by working in small circles, removing the black paint in small areas at a time.  The paint there is not even waxed and looks great, this part of the bike was quickly restored with no damage to the underlying paint.

Graffiti remover (I can't speak for all of them but if they are all formulated similarly then you should get similar results) does a fine job of stripping a bad paint job off bike body work.  Work in small areas, spraying on to the rag and then applying to the paint.  The top layer of the black comes off on the first application, the blue shows through after the second.

the black is coming off to

Of course, when someone blacks out a bike they might be doing it for aesthetic reasons, but I don't think I'll be assuming that any more.  It turns out the bike had been dropped pretty hard on its left side.  As I was removing the flat black it looked like I could see her hidden bruises for the first time.  The scuffs had all been sanded smooth for the black paint job, but as the extent of the injuries become clear I'll have a better idea of what happened.  It looks like the bike went down and slid without hitting anything.  It still has its original front end and various switch gear, so this was an asphalt slide that damaged the body work.

Looking at the bottom of the main fairing, I found that one side appears to be unpainted other than the flat black while the other is blue, so this is probably a replacement fairing.

I'm about half way through stripping the black off.  I'm to the big front fairings now, and they have a lot of real estate on them.  Working in small circles, this is going to take a while.

Once I've got it stripped down, I'll remove the panels, repaint them metallic blue and then paint the frame (burnt orange) while I'm in there.  The end result should be a colourful Ninja that proudly wears its stock metallic blue paint, albeit with some touch ups that make the bike even more visually interesting.

Notes:  

I picked up the Goof Off at Canadian Tire.  They had other brands there, I haven't tried them, but if I do I'll follow up with comments.

The factory paint job on an '07 Kawasaki Ninja 650r:  

Colourful is the new cool

What secrets lie beneath my Ninja's flat black paint?

I'm finding the Ninja to be more and more  manageable.  I don't think I'll end up on a sport bike forever, but I'm glad I started with one so I have a sense of what a road purposed bike is capable of.  One of the reasons I went with the Ninja instead of a KLR or other enduro bike is because it looked like it had been mistreated, and I wanted to make it happy again.  The bike is super dependable, rock solid mechanically, but it's had an interesting hidden life.

In the picture on right you can see where I've been working on the front wheel fender, taking the angry-young-man flat black off to find the original
Kawasaki Ninja metallic blue.  It's a beautiful colour, I have no idea why you'd want to cover it up, unless you've done things you want to hide... cheap.

Why would you ever de-blue this?!?

I'm guessing that the gas tank got replaced when the bike was dropped at some point.  The replacement tank comes in flat black, so the owner decided to cover up the scuffs on the rest of the bike with a thin (though apparently professionally applied) coat of black.

The blacked out look is aggressive, tough, very angry young man, but I'm not an angry young man and I like colours, and I don't want the bike to be invisible, I want it to be very visible.

I've removed the black from the front fender, a time consuming and tiring process, but I really want that black gone.  There was a bur in the plastic on the back, some more proof of impact, but I've sanded it out and it looks smooth again.  Between the paint remover and the scuffs on the fender, a good repaint will be in order.  I think by stripping and prepping the parts, I can save quite a lot on the repaint (prep is very time consuming).  I can also remove the parts that will be repainted, making them easier to finish.  The only part
that won't already be blue would be the gas tank, but when done it would match everything else.

Paint removal has been a trial and error experience.  I've tried sanding (almost impossible to do on the complex compound curves of the body work).  I tried acetone but it's very difficult to work with.  It seems to raise the paint and then immediately evaporate so the paint solidifies all mottled.  Paint thinner works well as a final step, removing the last spots and any black haze left.  It also does a good job of smoothing out any roughness left by the stronger chemicals.

For pulling off the paint in the first place the best thing I've found is graffiti remover.  It pulled the unsealed black off the clear coated blue with minimal damage.  If you work in small areas at a time, you can lift most of the paint.  When you've got it virtually clear, switch to paint thinner and gently wipe the final pieces away, then wash it all down with water.

It helps to have a variety of lint free cloths on hand.  Rougher terry cloths and even a soft bristled scrub brush helped to get into the black and loosen it off.  I could then wipe it clean with the softer cloths.  Even the graffiti cleaner dries quickly, so work in small areas.

burnt metallic orange

The current summer plan is to strip the bike back to blue and repaint it in the stock blue.  While it's naked I'm also thinking about painting the tube frame a burnt metallic orange.  It'll peak out from behind the blue and contrasts nicely with it.  The end result should be a Ninja that is not only visible, but doesn't look like it's had the living daylights beaten out of it.

Tim's Tat: inspiration for the Ninja
colour scheme

With some carefully chosen accessories that highlight the colour scheme, I should end up with a kingfisher Ninja that matches my tat.  With the orange highlights on the frame I could match up the brake and clutch levers (which are scuffed) with something a bit prettier; burnt orange levers would be a nice touch.

Colourful is the new cool.  Being visible isn't an option, I want it to be the goal.  Metallic blue and burnt metallic orange would pop and sizzle in the sun, be much more visible all the time, and would make for a happy, outgoing Ninja, rather than a war torn, black and beaten looking one.
