motor painting

[dividebyzero]

I was wondering if someone knew of somebody that painted motors complete.I rebuilt a motor from top to bottom(350x)and i dont want to have to tear it down to be painted.I didn't think about repainting it until i had it all together,but i'm already in a process of totally redoing my 350x...powdercoating frame,polishing parts,etc.Thanks for any help.

go to the hardware store, buy your color paint you want, take some duct tape/masking tape and tape off any open holes(intake and exhaust, etc) or if any parts are chrome or what not, basically everything you don't want painted taped off, then just spray it up. I imagine it would be somewhat costly to have your engine painted...

Thats what I do, but I sandblast first.
:-D :-D :-D

Yes sandblasting works nice if you have somebody nearby to do it, I don't have that option because my town/state sucks.

Sandlasting media is so fine I guarantee it will find its way into any seal, gap etc. it also will destroy tape covering anything. Sandblasting is for bare motors only, and even then it will find it's way into everything possible. Buy one of those good AM paints like PJ1 or hi temp motor paint whatever, then with it down with laquer thinner, cover whatever you want, scuff the existing paint - which in reality are your never really gone scuff everything like the cylinder fins and every nook and cranny, are you? ( people get lazy at this point). Like someone always use to tell me, don't bother unless your gonna do it right - or you just want to spiff it up to sell it because the paint you apply will not be as durable as a factory sprayed on and baked coating. Look at where the wear is, is it where you shift and brake? The new paint will wear off faster than the stock and probably look worse unles you prep it well.

if you use temp paint or automotive paint run the bike a few times to heat the paint up to cure. i didnt and the first time i took the bike in the sand all the sand stuck to the paint now i have a gritty looking motor

PJ1 high temp paint is the best paint to paint an engine with......period !
it goes on nice and will out last anything i've come across. You can pick it up at atv parts stores. you won't find it at wal mart or anything

Denniskirk also has high temp paint,etc and its also PJ1

I used that S100 engine brightener and it worked GREAT!My friend came over got some hi temp and sprayed the motor but the paint wouldn't stick because of the s100.It looked awesome in some spots but other spots it looked like crap because of it.Thats why i want to strip it down.I'm redoing everything on the bike even down to the nuts and bolts,the only problem i'm having is getting the motor done(stripped and painted).When i do get the bike done i will post some pics.I'm not gonna want to ride it after i get done it might get dirty(hehe),but the big motor,i just gotta ride it!

How much does sandblasing cost from a machine shop? I'm thinking of buying my own sandblaster with cab.

I bought the 60lb blaster from harbor freight for 100$ delivered, the cabinets are about 150$ sand is 7$ for 100lbs. The blaster I have is a pressure blaster not a siphon unit. It works fantastic, fast and down to bare metal, but it makes a mess, uses alot of sand and the compressor runs and runs. The silica sand is also known to cause cancer, but I think sporatic users are ok. In addition to my unit I would love to add a cabinet unit for smaller items. It recovers and reuses the sand and is cleaner and easier to use. Sand will find it's way into EVERYTHING!!!! remove anything you don't want contaminated!! Siphon units work ok but do not have the power of a pressure blaster.
