HONDA CM200 Engine Tear Down Pt.1 - GETTING SCREWED 

Two words. impact driver.

I feel your pain. My go to tool has always been an impact screwdriver on those stubborn screws. They're pretty cheap and you just whack the handle with the driver and it rotates the screw slightly on impact, and usually breaks them loose. You can set them to rotate counter-clockwise or clockwise. The problem is. You need to use them before the screwhead gets stripped. And be sure to ise the right bit. Most of those screws are a #2 Phillips and impacts will have a #1 and #2 Phillips and a couple of flat bits also. Sometimes it helps to hose the screws down with penetrating oil first. Great job on the vice grip and screw extractor advice. Excellent plans B and C. Allen head bolts. Good job. 2 beers up!

New CM200T owner here. Thanks for the video!

There is such a thing as japanese standard phillips head-like screw drivers. The angles are sharper on them. There is a set with green handles you can buy.

I know this is an older video, but Japanese bikes tend to use JIS screws and it's best to use JIS screwdrivers on them, not Phillips. That's why you see so many messed up screw heads on Japanese bikes. Best brand of JIS drivers is Vessel in my opinion - they even make a screw driver with a light duty built in impact driver. Get a couple of JIS screw drivers (#2 is most common) and you will not regret it.

Sometimes i put vise grips on a screw driver and lean all my weight on the screwdriver as i use other hand to rotate it with leverage from vice grips . ( i actuaully use a hex shaft phillips and put a wrench on it ) , little tricks you pick up on .

Those screws are a pain in the BUTT!!! Mine gave me trouble too. I did the same thing as you did, cutting slots in the head and use a flat bit. I hooked it up to an impact and turned the pressure waaaaaay down and backed them out with short bursts. Subscribed, and looking forward to the rest of the build! Till then I'm going to check out your other vids!

Could really do with part 2 I've got a cd200 engine in bits and need a reference as the manual is quite poo 💩 need a full tear down or full rebuild video.. Help a brother out 😁

Get some blaster penetrating oil for the future projects. Hit it and let it sit for a few hours and if the head is stripping because its old, use a piece of bicycle intertube between it and the screwdriver, that will help it grip without stripping more.

I just found your channel. Watching them through in order. I like that you share the not so easy moments with the projects too. As I do my own build I know there are moments where you bang your head against a wall. Keep up the great content.

Oh man you need to buy some proper tools, firstly an impact driver you strike wit a hammer not the electric type, the hammered type pushes the bit in to the screw as it turns, and the screws are not philips or pozidrive, they are JIS ( japanese industrial standard) and you need the correct bits or you strip the heads, and using pliers to undo the cam cover?..use a socket, if you carried on in this vain I'd be astounded if you ever actually rebuilt it, it was too painfull to watch, i wouldn't be suprised at all if you smashed the pistons out with a hammer next, please dont set such a bad example, that little bike deserves a bit of respect.

What happen to this build? Part 2?

So those of you that are saying “impact driver” I agree, but tbh I have this exact engine, and all the engine working tools you could ask for, after fudging with a couple of the philips head bolts with the inpact drill (both electric and pneumatic) After that I tried the actual impact driver, and the heaviest philips bit on it, no go, I ended up welding hex head bolts onto the heads of those and using the impact drill to get them off no problem. Between the heat and the added grip it seemed to loosen them up. If you don’t have a wire welder and you are working on old engines then please just go buy a cheap one and safety equipment, those screw extractors are only good for woodworking, I have never had any luck with them in any mechanical project.

1:10 what are you doing? Was it stripped? EDIT: IMPACT DRIVER MY DUDE!

Do you plan on replacing the old screws with some allen hex socket screws for ease of removal? That is what I did with any part of my bike that had the stubborn phillips heads and they work great. Im looking forward to the finished product!

Safety glasses..on the forehead..lots of critics in these comments. Thanks for making a video

JIS bits on impact driver are the better tool of choice.

Please show me how to do a valve adjustment, plus by the sound, my cam chain may be loose. I have not opened it yet

Im waiting to see what happens next.bcuz i have the same engine that u have(cd125)

Oh i get it now , getting screwed hahaha .

Buenas noches puedes compartir el manuel de la moto honda cm200

is it possible to find spare parts with you

Stuck screws. Impact Driver and hammer. Or cordless drill on low torque setting. No cutting.

i cant find any link to part 2 :(

This govornor CDI ignition timing???

No offense, but you're making the job harder than it needs to be. If you dont have a impact driver, use a torch to heat up the screws, spray it with penetration oil, then take the the screwdriver and set it in the screw and hit the end of the screwdriver with a heavy hammer. This should shock the screw and apply force. Try this a few times before resorting to cutting the screw

Are you using a Phillip's or JIS screwdriver?

Try the right sized screwdriver next time

commenting on my own video! Im cool.

that you will not experience if you have a knock screwdriver..

WTF is this guy doing. WOW!

Dude seriously.. I have built 17 of these parallel motors. From crank bearings to tappet cover bolts. My first motor is still running strong. My dad is a aviation grade tool and dye maker taught me everything I know. I disassemble that same motor in the time your video is long. Btw I cringed like fuck with the removal of those fly wheel cover bolts.. had to comment.

Jeaysus!!! Get a JIS screwdriver and an impact driver. Posidrive type drivers will not fit the se Japanese heads. Dremel???? FFS!!!! Barbarian at work.

That was painful watching you butcher all those screws. Get a manual impact.

you dont have it a impact tool bad mechanic!
