Title: Here's my shiny engine block Post by SavageWahine on 01/27/08 at 21:04:23 I've coated the matted high heat paint I sprayed one a while back, with some clear high heat clear engine enamel in the hopes that the dirt my engine accumulates during the rain, will wash off easier instead of integrating with the black paint So far so good! Looks like the engine enamel is holding up so far. I've been cruising around for about 3 hours today, and the paint seems to hold up. Tomorrow I'll check to see if the dirt washes off easier. |

Looks Good, You did some nice work! 8-) How long did it take you to paint it? However long it took it was def. worth the work that was put into it. Good going. I still say you should open up your own little shop doing that kind of work you definetly have a talent for it. ;) |

Title: Re: Here's my shiny engine block Post by skrapiron on 01/28/08 at 04:50:27 Just an observation... Last time I checked, the engine was air cooled. The matte finish on the cooling fins is annodized. Wouldn't painting the heat sink (cooling fins) , sealing it from proper air circulation, potentially cause thermal management issues???? (over heating?) |

Many air cooled bikes came with black paint on the fins from the factory, but that coating was always very thin and the manufacturer factored it into the way the bike was built. I've played around with Z900/Z1000s and you'll certainly be more limited on bore size for overheating if the barrels are painted. So-called heat-dissipating matt black paint loses heat because it's black, and black surfces release/absorb infra red at a much better rate than other colours. However, while a black painted surface will cool a whole lot better than white, it's still insulation compared to bare matt metal. That paint looks to be on pretty thick compared with traditionally used motorcycle black barrel paint, and with the clear enamel on top as well you're going to have insulation from the thickness of the two coats, and reduced cooling from the surface being shiny. That would be fine for painting an engine block when most of your cooling comes from a water system, but really could cause problems. Best to be careful on hot days, especially in slow traffic. |

Title: Re: Here's my shiny engine block Post by thumperclone on 01/28/08 at 07:51:32 block on my 06 is black,kinda rubbery lookin with the fin faces milled to the metals natural color..have seen 150f oil temp at a stop light when 100f air temp.. |

150f seems quite low, just 66c oil temperature, stationary in 100f air - if the motor can run that cool, it's a work of genius! Surely it can't have been fully warmed up? I'm used to getting worried in tuned cars if the sump oil temperature gets up towards 120c (248f), at that level you can worry about oil evaporating off the bores underneath the piston. If the little Savage can really keep to 150f on a hot day in traffic with coated fins, I guess it doesn't matter what you paint or coat it with. |

Title: Re: Here's my shiny engine block Post by SavageWahine on 01/28/08 at 10:43:10 A while back we had a post about if painting the block might cause it to overheat, and the main consensus was that it wouldn't. I don't have a way to check how hot the engine gets though. Any ideas? If it does get hot I can always sand the edges of the fins. |

Get one of those cheap infared temp guns (when on sale of course) in auto part store and monitor the head temp under different riding conditions. BTW it is a beautiful paint job, I wish you live next door so you can do mine too. Wait the minute, my is black coated from factory already. It is a little bit thinner than what you have there. I wouldn't be too concerned. |

Title: Re: Here's my shiny engine block Post by T Mack 1 on 01/28/08 at 17:00:19 Cooking thermometer .... wrap it thighly with aluminum foil if you are the neat freak type ( or if the person you borrowed it from is.... ;D ) You may loose a deg or two with the foil, but should be small amount... You will find the temp varies around the engine. Right side of the block should be lower because you're actually measuring the cam chain void. Around the exhaust port should be a hottie... :o . After riding a bit, the rear side of the block should be hot too.... Justin...... Chrome head covers??? |

Title: Re: Here's my shiny engine block Post by skrapiron on 01/29/08 at 04:17:05 You definately have to monitor your block temps at more than one location. Around the header, it is going to be hottest. Around the carb will likely be the coolest. Getting back to the original point, the several layers of paint that are now sealing the aluminum are acting as an insulator and are definately affecting the ability of the engine to cool. The factory anodized finish (the original matte black) does not seal the engine case like paint does. It is less than 3ml thick and does not affect the cooling. Once you added paint, you sealed the engine. With additional layers of paint, you are increasing the insulating properties of the paint. On the surface of the paint, the temps may feel normal, but under the paint they are likely much higher..... It looks good, but is likely to lead to problems down the road. |

Title: Re: Here's my shiny engine block Post by Onederer on 01/29/08 at 05:37:50 There have been some interesting observations. The infared temp gun would be the most practical, because it can be used on any surface. Just remember to read the instructions, because no one should assume that it is just a point and click device. I feel the spark plug area, and exaust temp would tell someone the most about actual engine temp. Monitoring oil temp, and comparing it to a baseline, could diagnose extra friction(clutch slippage), and reduced oil flow, if head temp and exaust remains the same. Monitoring oil temp tells how hard the oil is working, and if the limits of the oil is being reached. Do, whatever you like, I've seen plenty of riders with those impractical, high dollar, "custom" bikes, that seem completley satisfied. BTW, I see the hard work you put into it, and the engine looks great. :) |

Minor correction, Anodizing is a plating process and has fairly good thermal conductance. It is a poor electrical conductor. It does not chip or flake when corrosion gets underneath. It can be scrapped / sanded off. (side note, iridite plating is like anodizing, but electrically conductive). I pretty sure the black is paint or possibly powder coat.... I do know that the Sliver on my '01 engine is paint, .... it chips :( . |

Title: Re: Here's my shiny engine block Post by SavageWahine on 01/29/08 at 10:39:18 The paint coats I put on are really not very thick at all. Maybe 1.5 mil at the most. I only put 3 very thin black coats, and 2 thin clear enamel coats. I will buy a cooking thermometer (cheaper) and check the engine temp. |

Title: Re: Here's my shiny engine block Post by govmule84 on 01/30/08 at 06:12:44 FWIW, I think it'll be okay. Suzuki designed this thing, I am certain, with some malfunctions in mind...it prolly ain't great on the engine, but these motos seem to be tough boogers in regards to heat. They've got their weaknesses, but I bet yours'll be okay. Just ride faster for better airflow ;-) |

Title: Re: Here's my shiny engine block Post by SavageWahine on 01/30/08 at 13:28:45 I spent about 2 hours in the saddle yesterday, running around doing errands etc. While riding I touched the left side of the block to see if it was hot during riding, I was surprised to see how cool it was, almost like bathwater. It definitely got hotter when I had the engine idle in the carport for 20 minutes to cure the paint, but I only needed to do that twice. While cruising the engine stays cool. Mind you, it's not exactly summer weather here (about 70), so I'll have to wait till it gets about 90 degrees again. |
