Schools out. I want to strip my bike apart. service the engine, paint it and put it all back together in 2 weeks....

I am wondering how hard it is to remove the heads on the bike. Is it as simple as removing the 4 bolts on the head and pulling it off? I am going to soda blast everything and want to minimize the amount of stuff i need to pull off.

Are the heads 1 single piece  or 2 piece? ive seen the older monsters with the cylinder and the actual head with the valve system.

Are you going to paint or powder coat? And are you going to do the case and heads or just the covers?

everything. and by paint. Powder coating it would be way to much work.

Yes.

And do not paint if not absolutely necessary!!!

Take a looong moment and look at all involved, just the heads w all angles etc.....

Just a warning. [thumbsup]

On the older bikes (750, 800, 900) there is NO cylinder head gasket but the DS1000 & 1100 engines do have those gaskets which are about $100 for the pair (give or take...been a while since I ordered them). 

You can remove the cylinder head as you described, but you'll need a fresh gasket if you do that. 

2 weeks?  You sure?!?  That's a lot of work man.  I'd be sure I had ALL the O-rings and gaskets before doing anything if it were me...and I was trying to keep everything in that time-frame.



The *best* paint approach for the newer engines (2001 & up) is to use a paint stripper to remove the garbage that's masquerading as factory paint on the engine.  Then, use an acid-etching primer to provide a top-notch basis for the paint.  As far as the paint goes, I swear by the VHT hi-temp engine paint.  It's worked for all the customs I've built so far and I have no plans of switching anytime soon...


Best of luck man!!!

$100? damn. Thats a lot of $$$ spent on something to just to paint the heads. It doenst need to be super nice finish, it just needs to not peel off and crack.

Can you just mask and paint the engine as a whole?

I want to remove the engine cover any intake and exahust holes and mask them to seal it off. then just soda blast the whole engine as 1 piece. spray it clean with water, soap and a nylon brush. then use a self etching primer and go VHT on top. Id have to pull the pulleys to do that i assume.

Do you think chemical stripping is better than Soda blasting here? It would only cost me $60 bucks max (Thats 100lbs of soda) to strip the whole thing. and it would be easier to brush it clean than it would be to scrub chemicals off... unless theres a well price easy to use paint stripper that i can litterally scrape off, and then use a soda blaster to get the nook and crannies.

Does the VHT self etching primer work well?

how long did it take you? And did you actually use sand, or do you mean media blasting? i have soda blasting and glass blasting in house, i can swap out the glass for something else since its inside a container.

I've got no FHE w/soda blasting but I *guess* there would be no problem with it so long as all the holes were covered up.....

I just did a motor that had been soda blasted.

It's pretty much a waste of time IMO.

Not quite aggressive enough.

The combo idea isn't bad.

Chemical strip, neutralize with water and dry, soda blast, prime and paint.

Is this "soda" blasting the same as the typical "Silica" sand blasting?

You are gonna be one busy man trying to do all this in a 2 week timeframe.  Its possible, but I doubt you'll be doing much else in that time.

I would try the combo strip method as well, assuming you have the resources.  The OE engine paint is really tough to completely remove.

Good luck and of course let us know how it goes!

IIRC putting soda into a regular pressure blaster does not work very well/at all.  Apparently the retrofit kits are actually made for a reason ;D.

I have no FHE with this but it's what Google has told me in the past.  Also, HF now has a small soda blast unit for $99.

2 weeks...GL
