Title: How about painting the engine??? Post by Andreas on 07/23/13 at 08:30:23 Hi guys, since my bike is completely teared down for restoration I've came up with the idea of painting the engine BLACK (yeah baby!!! 8-))! What do you thing about that? Do you have any recommendations? What should I take care of? I am thinking about using fire resistant spray paint. Is this suitable? Regards, Andreas |

Title: Re: How about painting the engine??? Post by Dave on 07/23/13 at 08:40:30 Most of the engine was painted from the factory to start with. The center cases, cylinder, head and cylinder head cover where either painted silver or black. The left and right side cases are polished and clear coated from the factory. Good preperation is important. The engine has to be clean and all loose and flaking clear coat has to be sanded and feather edged. All the existing paint should be scuffed with sandpaper or scotchbrite to give the new paint "tooth" so it can adhere well. Spray paint should be at a minum and engine enamel that can withstand temperatures of 350 degrees or more. Exhaust paints may not be necessary for the engine. |

Title: Re: How about painting the engine??? Post by WD on 07/23/13 at 09:01:24 Mne was Chevrolet red-orange for about 12 years (maybe 13 or 14). Repainted the center sections black a couple weeks ago, painted the side cases aluminum (with pearl high heat paint). Scraping the head/head cover fins clean on their edges. I use 500*F paints. They don't smoke as badly when curing as the 350*F paints tend to. The fumes off heat cured enamels are pretty strong. For the exhaust system, use BBQ grill or woodstove paint. Expect to recoat it a couple times, the finish tends to solvent pop when it is curing if the base wasn't perfectly clean and lightly sanded before painting. When I start reassembling my antique Honda race bike turned street bike I'll likely be color matching the outer cases to the fork sliders and the tins. British Racing Green. The rest of the engine will be black or silver, likely black inner cases, head and head cover, with a silver cylinder bank ( old parallel twin sloper 250). Look at older custom motorcycle magazines from the mid 70s to mid 80s for your engine color scheme. Or go here...http://www.dotheton.com/forum/index.php?topic=28778.0 currently 10 pages long, some of the photos are long gone but there are a few absolute stunners... The pic below has about the right amount of paint to alloy showing. I have one very similar going in one of my rides... Not a bike engine, but a good reference anyway. |

Title: Re: How about painting the engine??? Post by Andreas on 07/23/13 at 09:25:45 WOW!! Thanks guys. That was helpful! My idea was to paint the crankcase, cylinder and cylinder head black. Some covers on the engine e.g filter cover, cylinder head covers would get a nickel or black chrome plating. Also the exhaust system would be the same. Now from the link provided I really liked the gold color!!! I am really happy now!!! ;D Thanks again! |

Title: Re: How about painting the engine??? Post by WD on 07/23/13 at 09:52:10 I'm doing this, but in dark green, with a headlight and a brake/tail light. The red one is a 305, mine is a 250 with 305 shocks, forks and carburetors, plus street type low pipes and mufflers from a late 60s or early 70s aftermarket source (most likely Rocky or Nempco). Make it yours, ride it until it falls apart, and repeat. |

Title: Re: How about painting the engine??? Post by Andreas on 07/23/13 at 11:42:31 If two parts of the engine are supposed to be painted the same color , should they get painted separatly or fixed together in place? |

Title: Re: How about painting the engine??? Post by WD on 07/23/13 at 11:49:35 Depends, do you want it to look correct, or to have painted gasket edges. Some parts were factory painted separately, others once the sub-assemblies were bolted into a unitized assembly. So, actually, either way is "correct", just depends on the parts involved. Pulled the side cases off my engine, wrapped the carb with a bread bag and sprayed the entire lump as a unit. Even left the starter on. Mine is rider grade, show grade finishes you pull the peripherals off the engine. |

Title: Re: How about painting the engine??? Post by WD on 07/23/13 at 12:09:18 Wish I could claim the red one as mine, just an example of how my 1963 Honda is getting built up. Mine is dark green and in a zillion pieces scattered all over the forge. And my front yard... Mine has low mount side pipes. The one I attached the pic of in an actual competition bike. |

Title: Re: How about painting the engine??? Post by WD on 07/23/13 at 12:53:02 I don't know, it's the size of the attachment . I'm techno-phobic. Wish I knew who built that L6. I'd get them to help with the 230 Plymouth engine for my 49 Dodge truck. I thought you meant the bike... Forgot I added the L6 flattie pic. |

Title: Re: How about painting the engine??? Post by Pine on 07/23/13 at 12:54:12 its not a "DIY" think but I love powder coat!!! http://https://lh6.googleusercontent.com/-TT_MB3LZGq4/RtRgKzY6QZI/AAAAAAAAACw/R7pI0KjVRjI/s640/P1010227.JPG My '65 tbird engine ( actually it came from a Merc) the intake, both exhaust, all pulleys and brackets were powder coated. The valve covers are spray can ( and badly) by the folks that did the sand blasting. The numbering is me.. with gold leaf paint and a brush... http://https://lh5.googleusercontent.com/-TLos5Df8zg8/RtRgMjY6QbI/AAAAAAAAADA/a8VBqtdNi3s/s640/P1010229.JPG other ways to "blow money": replace bolts with hex studs and chrome acorn nuts ( with nylon washers) replaced all the oil pan bolts with SS, except for two that got studs ( locators) stickers!!!! http://https://lh5.googleusercontent.com/-FL-6uismWOo/RtRgOjY6QdI/AAAAAAAAADQ/utv-ya8Jvy4/s640/P1010258.JPG |

Title: Re: How about painting the engine??? Post by ToesNose on 07/23/13 at 18:13:33 +1 to what Dave said, prep is the key! Make sure it's immaculate and degreased otherwise with the heat of the engine it'll peal or bubble :( WD I like that red 305 Honda! I just looked at a Honda Dream 305 the other day, but It needs too much work I fear :-/ |

Title: Re: How about painting the engine??? Post by Andreas on 07/24/13 at 10:12:56 My savage is also scattered apart in a zillion pieces. I hope I can post some pictures in a couple of days with the first painted parts. I am in the cleaning stage now... |

Title: Re: How about painting the engine??? Post by Andreas on 07/31/13 at 01:38:07 First part (clutch cover) was painted, and I have to say it was a complete success!!! ;D I followed your instructions about the cleaning with some more additions. First I left the parts sucking in oxalic acid solution overnight. The etching procedure gave me this: http://s21.postimg.org/qmn18ws3r/20130725_185627.jpg After I've sanded everything, really, really, really (and I mean it) good, I sprinkled everything with water and cleaned them dry with a lint free cloth. Because I was too excited I forgot to take a picture of that stage... >:( Then the painting. I used spray paint (matt black) suitable for up to 800 Celcius (do the math for Fahrenheit... :P) http://s15.postimg.org/vqbn5t2u3/20130725_195129.jpg I've read somewhere that these paints cure better if you "cook" them with a butane torch. Why not? I gave it a try and it does work! The paint cured and it got really tough. http://s13.postimg.org/ldppy1ig7/20130725_204929.jpg I've also painted the alternator cover the same color and the oil filter cover, sparkling silver. On silver parts I'll paint a clear glossy varnish. My next step is the crankcase. This is the most difficult but I will come out as a winner!!! |

Title: Re: How about painting the engine??? Post by justin_o_guy2 on 07/31/13 at 06:39:03 Butane is a bastard gas. Propane, man,, Pro PANE,, I just cant believe ANYone who would use BUtane can do such fine work,, shocking,, truly shocking,, Do you not watch King of The Hill? I thot everyone knew these things,, |

Title: Re: How about painting the engine??? Post by WD on 07/31/13 at 09:03:49 Please tell us that you pulled the stator out before the acid bath... the copper wires are individually lacquered, for a reason... Looks good, but, how do intend to get cured paint off the oil check window, or did you tape it up before spraying? I did not when I repainted my engine last month, cleaning the window off is a nightmare... |

The stator got a really nice acid bath!!! ;) I am just kidding. I removed it first. I taped the oil window, paying attention on the edges. It ended up really nice and clean |

Title: Re: How about painting the engine??? Post by Andreas on 07/31/13 at 10:53:21 These are the rest of the painted parts: with the oil filter cover on. As you can see I haven't remove the tape off of the oil window. http://s15.postimg.org/706ryfv6j/20130731_203119.jpg the stator cover and the gear shift cover http://s23.postimg.org/es4y788p7/20130731_203431.jpg |
