Hi,

I have bought me an Monster 620 03-mod. The thing is that the former owner has used the bike during the winter, and the paint on the engine has taken damage from it because of the salt.
Is it possible to paint it again, without totally ripping the bike in pieces? In that case, how?

Thanks to all that gives reply! [thumbsup]

YES it is not that difficult , remove engine from frame, remove EFI or carbs , seal all openings with tape , remove belts and belt shrouds , clcleamn with solvents and remove all grease ,grit ,dirt flaking paint etc.

Spray using HAMMERITE SMOOTHRITE ENAMEL either black or silver . replace fasteners as required with new ones and remount engine in frame etc

The hot engine when restarted wil bake the paint and its very durable.

There are plenty of options for painting the engine.  The best ones required you to disassemble it completely and bake it after painting (although the engine heat can do most of it). 

You might be able to paint parts of the engine in-frame but you should plan to remove multiple parts and spend plenty of time masking.  Sounds like you just want to re-coat the bottom?

I use a product called Duracoat from Lauer (LCW) which is originally used to coat firearms.  It is a two-part enamel coating which is sprayed on and is heat resistant up to around 600F, chemical resistant to pretty much everything except strong acids, and the strongest paint strippers or bead blasting.

I used Duracoat to coat the heads on my Alazzurra (pantah 650 engine).  They are originally black and the factory paint was peeling and crap.  I made a mix of their flat and gloss blacks to produce a semi-satin finish and sprayed on two coats using the Preval aerosol cans.  I baked the heads in the oven for about an hour at 300 F and that was it. 

They have a huge array of colors as well.

I use 2 part automotive urethanes and have had no issues.

The surface of an air cooled engine really doesn't get very hot.

Just like it holds up on a car.

Those things are part of the normal environment for auto paint.

my horizontal head is black and disgusting, the paint has a cracked skin appearance. I ve been thinking about painting it as well, but how to strip is my question.

Do you think i can just pull the engine, mask off the intake and exahust and just hit it with aircraft grade stripper?

itd DEFINTELY want to strip the paint before i repaint it the orignal finish is compelte crap.

my verticle cylinder is fine though.

yeah, you can do that, but your masking better be waterproof since the stripper needs to be taken off somehow.

maybe mask it all off, apply the stripper, wash it off, then take off the masking and put new on. 

i assume aircraft grade means alu safe.  use a lot of wire brush after you strip it, it won't get everything.

I was hoping hte aircraft stripper would peel it off  easily.

if i have to work, i might as well put a steel plate over the exahust and intake and whip out my soda blaster. It'll cost me $30 bag probably, but only take 30 minutes with clean up.

Cool, another excuse for me to pimp this picture of motorcycle parts baking in the oven:
