engine

So I have finally started to put my motor together.:D When I took it apart I was careful to take pictures of everything so I would remember where parts went. As it turned out my hard drive on my computer died. Along with all my pictures. :banghead: :banghead: What I am curious about are the...

Just thought I'd drop a note here although I'm sure alot of you have seen already. Go to ebay and search xs400 piston rings 24 bucks for two sets. Several seat are availiable. I order two sets one set first over and one set 4th oversized. Just thought I would put it out there. Get them...

Hi all thought I'd drop a note on here and ask a question regarding pistons. I like most of you have spent a long time looking around for oversized pistons and rings. Sure you can get them but they are costly when you compare them to the price of other rebuild kits for more common machines. I...

To all you fellow xs'ers out there, what would be a manufactuare that you would suggest if you wanted to buy gears for and what ratios would you suggest to get the most speed out of. Many thanks

Just wondering this. Also has anyone used a copper head gasket to raise the compression as well? I might do a little of this when I ( if ever) rebuild my engine.

I was just wondering how many miles have you gotten out of your original motor without the need to rebuild? I'm curious how far they can go. What year and miles please?

Now with video! Common internal failure? My friend is killing his second one! I've got a good friend, who probably shouldn't own a motorcycle. I'll leave that at that, and of course we all know lack of attention will eventually cause anything to fail. Getting that said and out of the way, he...

Hey guys, I got my chain today, still waiting on the manual I bought. I went with DID, after som research they seemed to be the best for the money. I really want to get the chain on so I can get out a few more times. Any hints or tips on changing out the chain seeing I don’t have a manual...

So, i was thinking of boring out an xs 250 to a 400. Is it possible. I've checked on the workshop manual and the only differences are piston sizes and cylinder barrels. Would a swap fit straight in? And if so, do you know from where can I purchase at a reasonable price please? Thanks guys

So my 1980 XS400S has been running fine for months. Now it wont start, kickstart really sucks and rarely turns over a cold engine, but works fine once the engine is hot. Electric start has been working fine all along, but now it is not. The starter motor is spinning just fine, but it sounds...

So I have an xs 400 that I bought around a month ago. It ran when I bought it but has been a severe headache since I got it home. My first discovery was that the left side carb was messed up - the float mount had been broken off and glued back in and the glue had come loose so the float was...

Only my 2nd post and I'm looking for help. Be warned, it won't be the last time, I'm sure. :shrug: Anyway, I just bought my first cycle, a not-yet-running '82 XS400J Maxim that's in need of TLC. The issue involves the tranny. It seems to be stuck in neutral. The pedal moves up & down a bit...

What's your feeling about this? I have always heard that you perform a compression test by removing all plugs, engine cold and throttle fully open. That's what I did this A.M. on my engine but the test kit of my son's said to perform the test on a warm engine. So which is it: cold or hot...

Hi there, My name is Bram. This is my first season riding, and I love it! I have a Yamaha 1983 XS400 Maxim, and it's been running really great, though recently there's been a weird whistling coming from the ignition (or at least in that general area). It worries me so I haven't been riding...

Well, even though I've been working over weekend I have managed to put the bottom end in the frame and fitted the clutch window. It was really late when i was doing it and forgot to check the kicker, damn I ve instralled it wrong :banghead: nver mind, will have to get a new gasket now :doh...

Hey all and thank you so much in advance for whatever help you can give. So I just bought a 81 XS400 Special so the GF can learn to ride this summer. Over the winter I want to take it down to frame and make a Cafe. I know, I know, not exactly original, but it's something I've wanted to do for...

First off I guess I should start by saying hello. I'm a new xs400 owner and first time bike owner. I just recently stumbled across an xs400e (well two of them) as well as two tx 500's (73 and 74 model years). It started off I was finding class projects for my grade 10 auto class and it ended up...

I need a new clutch cover for my 78 XS 400 2e. Will this cover from a 78 XS 400 heritage work for me? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=380280969422&ssPageName=STRK:MEWAX:IT#ht_1280wt_918 Thanks for any help!

Hi I am new to this forum. My Name is Dennis and I am from The Netherlands I own 1 custom build bobber xs 360 c and a standard xs 400 Maxim. My question ! I was driving my xs 400 the other day when the road got very slippery. There was oil leaking from my engine on my rear...

Hi, Well the bike is back in one piece and running. The bike runs really well below 4,700 rpm but once you get above 4,700 rpm the engine runs rough and the engine loses power. However once you get about 5,800 the engine picks up again. I should also mention that it takes a while for the bike...
