I bout a project with a busted engine...looking for something to replace my current 440 with anything that will fit with limited fabrication. So if anyone has done something like this or knows anything about I'd be thankful for any help

Could save yourself a lot of trouble by browsing eBay for a clean identical engine. Keep the other around to pull parts from

I've looked they have one that's running for almost 400 dollars. And that's what I paid for the bike. So I'd like to find a cheaper way.

Any kz400 or 440 will fit, any year, the top mount is different on the earlier 400's but that's it. The pre78 400s had a different carb spacing but the carbs can be modified either way to work.

Would a cm 400t work?

you got a cheap project because the main part of any motorcycle didn't work. the running engine for 400 is probably a good idea if you know it runs.. 800 total and a bunch of extra parts isn't a bad deal

It looks like the cm400t is part of the frame, meaning there is no lower cradle like the kz440/400 have. if it's small enough you can probably get it to work, but custom motor mounts and aligning the sprockets right might be more of a PITA (for any motor you go with that's from another model) than finding another stock motor. Cruise craigslist, you'll come across a deal eventually. I got a complete 440 with good motor for $200, and that same weekend I got two parts kz400's for $50 each. They pop up every now and then.

Alternatively, the kz400 is a super easy motor to rebuid, and there is a good kz400 support website if you look, if you are new to engine rebuilding but are handy with a wrench this is a great motor to learn on.

I agree. It'll save you a huge headache down the road.

Thanks guys that helps a lot I'm a millwright so I'm pretty handy with a wrench but when it comes to gas engines I know very little especially about motorcycle engines but I have been thinking about rebuilding. I was told that the bearing spacers in the crank might be bad. It was knocking super loud and kept frying the starter. So Im thinking about taking the engine out tearing into it and trying to rebuild.

Ok after a little research I got a clymer kz440 book and have prepped my kitchen table (much to the ole ladies dismay) for tear down. I think I'm going to gut it and see what happens. Hopefully post pics this week

I have a 79' KZ400 with a seized engine waiting for me to finish up my current project. I'll be keeping an eye on your engine rebuild as you post updates.

Can I put a new bottom end with my old top end? Sorry if it seems like a stupid question, again I am completely new to motorcycle engines.

So I'm starting a photo bucket tonight of my progress so hopefully have pics up tomorrow. But I have the top end completely apart and it all looks good so I'm pretty sure it's my crankshaft that was causing the knocking. But also I'm in Jacksonville NC so if there's anyone around who doesn't mind showing me a thing or two. I wouldn't mind at all

I think an EN 454 motor will bolt right in.......

If you can modify a frame the world is your oyster, I bet a six pack a KZ550 would slide right in there, image search the two cases. and frames. EN450 is a whole other animal, so it would require some modification.

I've got the engine mostly apart. It's pretty terrifying really. Feel like I'm flying blind. I'm pretty sure my crankshaft is wore out from the research I've been doing. So I found one for like 50 bucks on ebay so I'm gonna start there

I really hope you bagged and tagged everything if you have a piss poor memory... if not do it now... and get a shop manual from somewhere asap... lots of em online in .pdf form there are also a lot of great schematic's and some hard to find wiring diagrams at http://www.cmsnl.com/ sometimes oem hard to find parts you can't find anywhere else.

I personally prefer the used giant junkyard called ebay. I miss the yards from yester-year it's where my first motorcycle came from... Yamaha DT from Armstrong's on Market used to be in an old gas station, long gone that guy was fucking awesome I think I was 14, reminded me of my 2nd dad so to speak true grit and no bullshit... who they were and unapologetic about it. I heard Armstrongs has moved, but I've been scared the old man isn't living anymore... and I don't want to find out immortal in my eyes. I met an awesome guy in Columbia SC named Smiley I went up there one Sunday and he and I talked for what seemed hours, offered to sell me a chopper he had just finished building... for 2 grand, this was like if a god came down the mountain and said hey see the world from down here? 10 bucks and I'm like um I got 4.

904Punk when we came up poor dude was thin as a rail and half fuckn froze to death... he stopped in town for clarity, I asked the old lady to toss a wool blanket in the dryer, while I got a bottle of whiskey out as dinner was about ready. We went up there, they were loading everything out of the back onto the trailers ready to go for scrap... I was like well shit maybe we can get a good deal on some shiite! Walk in Dont recognize the two dudes Sunday was expecting smiley, I said my friend here is looking for a seat... the guy was hmmm i dunno not really selling these days, I said is smiley around havent spoken to him in awhile I'd like to say hey, they looked a bit grim and said they lost him to cancer.

That's why everything was loaded up... they lost their backbone, that held that whole place together. 904 and I were able to step out back they were looking at a bike and pan and I was glancing around at the history about to disappear, it was like we were ants walking on Smileys corpse and it broke my heart. So that's what has kept me away from Armstrongs, all those old gods that we know were there and in some shit they dont die they slowly fade away.

Something smiley said as we were standing out back and he was telling me all out his chop, his eyes would glimmer when I'd point out a detail he had a story about every single part what went through his mind as he was making it, it was like transcending time and space, we stepped back after that zoomed in inspection to take it all in and it felt like we were one... then out of no where he cracks out loud with "maybe I should put some fuckin inverted forks on it like them damn bobber kids are doing these days." I said it's perfect... that's your soul right there. He got quiet for the first time since I walked in the fucking door, he had wise cracks like putting britches on a seagulls and shit, so much I couldnt remember but wish I could that was so damned funny. He was willing to let the last piece of his soul go out the door that day for the low low price of 2k. But I honestly think he snuck it in my back pocket when I wasnt lookn.

Respect always comes from seeing the man behind the like. American, Japanese, European, imapean... whatever, it's the heart thats here because their soul goes into their bikes. So I dunno exactly what he snuck in my pocket to make sure I carried it with me, but whatever it was. I am a better man for it ride in peace smiley. We've got an older cat here, I've seen people disrespect... maybe he seems a bit strange hell that maybe the case we all are to someone that doesn't understand and doesn't want to take the time too... but consider the days, because thats all we have here, and when those are gone if you're lucky you'll also fade away. I have a feeling what smiley slipped in my pocket is heart and it was pure gold, and I havent been being greedy with it, but have been slowly shaving off a piece for all of you.

I guess when you are tasked with such a big heavy golden heart to share it sort of transmutes yours too, and in that process... we see time is the most valuable thing when all is said and done, and how you spent it? well I hope it was a hell of a lot of fun. I hope we all get many many more especially from Wolfie who keeps threatening he doesn't have much more. So go over there in his thread and have a seat, ask and learn... and maybe you wont be in a recreation but start living it... some of you already do cause you learned this shit from a geezer too. Wolfie I'm gonna come up to Strange Days even if I have to cage it... but if you try to slip something in my back pocket as heavy as smiley did? Ima kick you square in the ass brother. BTW I don't drink no damn; citrucel and vodka but I'll bring some vodka pretty sure youre stocked on the citrucel... supprised it's not tang cause you're outta this world but shit youve prolly had enough tang to make Rubsy faint as for me a gentleman doesn't tell tales.

lol forgot where the fuck I was... um yeah... motor apart and shit take pictures use the manual, read the manual like it was hustler(that was my personal fav growing up if I managed to score one) kids so spoiled with porn these days you hide one in a link with two dudes fuckin helicopters.

sorry to take your question thread off the rails cub... if it bothers you I am sure a mod would be happy to move it for you.

I read all of that Jetblack and thanks for taking the time to type it out. I've met up with wolfie a few times. One time when he met me half way to give me a set of front forks, because I'd done something really stupid on one of my bikes. Man asked for nothing more than a handshake and that I return the caps after replacing them with my old ones, as he needed em for a build he was working on. Another time I rode up to his area for a ride with a few others and lunch at some local diner. Anyone who gets the chance to sit and listen to an old-timer talk for a spell, would be well advised to do so. You are absolutely correct that these "old kooks" have an amazing amount of experience and talent to share. When they are gone, we will all be a little bit poorer for it.

I'm the same sort and well I have good days bad days sometimes lasting far too long, I've kept people at an arms length trying to be more than a friend in just title and I really don't know why. Some coping mechanism I have been trying to figure out, still working on it. Not saying Wolfie is like that at all hell he probably has some advice about it though.

As for the time? I sort of got lost in the moment and didn't notice any passing... but if it's any value after how I have acted the past few days? Thanks.

Hey man if you haven't seen already there is a website kz400 dot com (hope this is kosher) that has a link to the factory service manuals (and even a engine breakdown walkthrough with good pictures) which will help you out a lot more than the clymers, although having both together is even better. If you need parts go to partzilla dot com and you can look up the model and year and see what NOS parts are still available such as hard to find o-rings, clips, etc. Everything is pretty easy to tear down and put back together except for the gear shafts because of all the parts involved on those things, but if you just inspect them for damage/ wear instead of taking them apart piece by piece it will save you some headache. Hope the teardown is going okay!
