Has anyone ever converted the XS400 into a dual sport? I would like to run some bigger DOT/offroad tires and get some more suspension travel out of it. How would I go about all of this?

6,000 miles. Has an oil leak and the electrical is shorted or something. I was riding it up the street to figure out where it was leaking oil and I lost electrical power completely. New clutch cable and new brake pads installed two weeks ago. Done messing with it so it has to go. The parts...

My Seca is up for sale. Front brake system rebuilt, carbs rebuilt, new battery. Has some scratches from falling on the exhaust and the levers. Has a slow oil leak and older tires. I do have a parts bike that I am willing to throw into the deal for some extra cash.

The engine is disassembled. Have 99% of the original parts. Post here if you need something and I'll post pictures if needed.:)

Hey, I finally got around to starting up the bike today. She starts perfect on the first turn off the starter with no choke (new plugs and filters) but after about 5 minutes at idle she decided she wanted to rev to 3k and 4k if I don't turn her off, again choke or no choke she does this even...

I got the xs fired up today for the first time since I bought it! Float levels were off :doh: I'm still waiting to put everything together and register it because I know I'll be out riding in this cold weather. Thank you everyone who told me what the problem was! Also! I got my bone marrow...

I keep looking at EFI the more I look at the carbs, I'm considering learning how to convert bikes to EFI for two reasons: I hate carburetors, and it might make me some good money as I have quite a few friends interested in converting to EFI but not interested in experimenting.

So I finally got the second seca to start on its own without fluid. But it won't come off idle. Also has the funny habit of not wanting to idle while its leaned over on the kick stand. Any advice? I checked for leaks at the boots with propane. I think maybe its too rich since the choke causes a...

Does anyone know where I can get my carbs ultrasonically cleaned in michigan?

Well I picked up a second "just in case" parts bike for 200 bucks. I brought it home changed the oil (lesson learned) and swapped the obviously dirty carbs with my carbs that had just been cleaned. I got the bike started with starting fluid and hit the throttle and it revved right up! I was so...

Anyone need parts? I have two of the bikes so I'm parting out one of them.

Hey guys, I'm getting the bike back tomorrow with new reason to celebrate. Some of you might know I have a suspected spun rod bearing. I decided since my mechanic wants 300 minimum for bottom end work I will be doing this one on my own. I tracked down a slightly used crankshaft and rods for my...

Yeah title pretty much explains it. I finally tracked down a bike in my area to kindly donate its engine to my '82 Seca cafe project. I'm hoping it a DOHC so I can easily swap my beautifully cleaned carbs on to the little twin.

What should my compression in my '82 dohc be in psi? Thanks, I know I know, im being lazy.

I have had no luck finding any mechanic in my state who can fix my bike. So I'm looking for a new engine for my '82 SECA. If anyone has any leads I'd be very greatful. Thank you!:banghead:

I need a head from an '82 seca, PM me or post here if you have one you're willing to part with.

My mechanic just finished the carbs and the original problem was not in the carbs i guess.

do I just swap my speedo and tach cables out? or is there anything special I have to do?

I've taken my bike into every mechanic in the area and none of them will service a bike this old, besides one, which was evicted while my bike was in the shop. So now my bike is in pieces, and the carbs still aren't fixed. They told me the seat for my float needles is broken or something to...

Hey everybody, first time here. And I'd love to say that its a great site. I've had my 1982 xs400 seca in the shop for the last 3 weeks to have needles replaced and they called me today telling me they won't be able to do it because yamaha doesn't manufacture the needles anymore. Can anyone...
