i'm getting ready to strip the paint off my motor, but was wondering if typical paint stripper will work on the grey parts on the motor (mainly the case, clutch cover and everything else that color). the paint on the head seems like a normal paint stripper would work, but not sure about the rest of it. let me know if anyone has some advice.

I would hit it with some sand paper b4 i even tried using the stripper.
Just sand it enough to scirff the paint up a little........
It will deffinatly help the stripper work better.

spray stripper works good ... but the **** in a can were you can just over coat every 20 minutes with a brush is the ****....you pay a little more but you get more and its more affective!!
Oh yeah another tip..once on yer skin,the **** stings a little..lmao!

zip strip can sting more than just a little!!! i've had my battles with that stuff back in the days when i was in bmx and constantly stripping and painting bike frames. i dont know if they still make it or not, but that was some potent ****

after u scuff it up...and apply the sripper.....cover it with some plastic wrap or a bag ....it makes the stipper work much better.
You may use gasket remover on the entire head and cylinder also, that's what I just did to get rid of the black paint over the entire engine. Be warned that the paint is also everywhere inside the head and cam chain passage in the cylinder also, and you'll have to more than likely remove all of that also. You will need to know someone with a small bearing puller to remove the needle bearing for the camshaft, it'll rust over when you rinse out the head with water and solvent. Remember to take out all rubber and plastic components such as the cylinder oring before dousing it. To get off stubborn deposits you should use the red scotch brite pads on there, they do wonders. The paint will also be inside the oil gulleys, so after you spray in them just force a ball of scotch brite down them with a rod/pencil and repeat several times until they are clean. This method works excellently and your head and cylinder will almost look as shiny as a motorcycles. Do not get your engine work done until the paint is gone, such as boring of the cylinder since it'll rust slightly during the cleaning process. If that happens you'll have to hone the cylinder or bore it all over again. You will also need to build a valve spring remover and disassemble the valves to clean any debris off of them. Follow all of the book's guidelines for disassembly, and be sure to have everything new that you'll need. Excess shipping charges for valve stem oil seals and such add up quick.
Here is my cylinder during assembly, keep in mind this is a '01 motor which was previously all black:

Im not 100% positive but wouldnt paint stripper have a bad effect on aluminum, like some degreasers i have used which leave spots on aluminum that are next to impossible to remove. Just something to watch out for.
And thats one great looking cylinder haha, i was going to try and strip mine down but just wanted to get my motor together haha.

thanks boxhead. i hope that your technique works better than the stripper. i would say that 75% of the paint came off, but since the head isnt smooth, i have black in the pits on it. i'm gonna give the gasket remover a shot.
since it could be a month or so until i am able to get all the parts for the head and cylinder and to get it machined, should i wait to disassemble it and just strip all the paint on the exterior and wait to do the internal nooks and cranies until i'm ready to get it machined?

I would get right to work on the paint stripping, it takes several times of spraying the paint stripper/gasket remover and scotching it to get rid of those pits. You don't want that gasket remover anywhere on your bike, it damages non metals quickly. Make sure you wash the components with simple green and a good scrub brush in between each spraying and scotching it also. The gasket remover leaves a slimey film from the reacted chemicals. You have to watch what type of brush you use also, strippers and gasket removers will dissolve plastic bristles/brushes quickly, and the sludge it leaves (from melted plastic) is a bitch to get off. You should also use the warmest possible water, that way the water evaporates quickly from the cylinder so it doesn't rust much, it is cast iron. That gasket remover or stripper will make plenty of nasty fumes when it hits the warm water, try to do it in a VERY well ventilated area or with a charcoal filter mask on. Keep it off of your skin also, you'll get a drop or two on you in the process regardless. It starts a burning sting wherever it hits you,and feels like an acid or strong base is on you.
well, i picked up some gasket remover today. i'm gonna give it a shot later on. earlier we had to stop by an autobody place and we asked them what stripper they recommended. he said airplane stripper. they had that at autozone too so i'm gonna give that a shot. i'll let you guys know how it turns out for your future reference.
the gasket remover was an aerosol, but i went with a regular quart of the airplane stripper. i tested it on a small spot earlier tonight and it works better than any of the other strippers that i tried. i was beginning to think the damn case was powdercoated because of the fact that the other strippers didnt hardly phase it. i hope the gasket remover works good on the head. i plan on spending the whole day stripping it. hopefully by the end of the day i will have some pics to post.
gasket remover seemed to work on the head. i'm gonna hold off on that part though. i'm wanting to get the case totally stripped and painted black. then i'm gonna take the top end off and all the covers to get them prepped. thanks a lot for all the advice. i appreciate it
ok, that factory paint on the engine case is a bitch to get off. i've been working on it for a few days straight. i would say that i have about 85-90% of it off. the only parts that are left are all the tight nooks and crannies and the very bottom. i've been using an sos pad to rub on it and it does help, but it is still a total pain. has anyone ever sandblasted aluminum? not necessarily with sand since there are different mediums to use. i'm gonna give it a shot on a small area that cant be seen. if anyone has any experience with it, let me know.
