I met an old man a few years ago who slagged off the xs400 he had, saying it ran backwards!! then preceded to tell me he got the timing and leads all wrong. So it can and does happen....to the select few!!

check out the web site as i think they charge a flat fee of £20 courier. a more southwest based powder coater is Griffs reality motor works in Bristol, they have also done work for magazines, but i havn't used them.

I used triple-S powder coaters who prefer to cover all the threads themselves. they are based in keithly nr Leeds. google triple s and the web site is full of info what to do. Classic bike and classic motorcycle mechanics use them, 'nough said.

I have seen your question in the german xs400.de forum, and I think those guys are probably your best bet as that model was popular there. I'm sure that one of the posters has a 12e bike and has pictures of his conversion. check out their signatures.

your right, I looked on the micro fiches and can see no oil cooler reference. the only alternative i can see (as long as you have the oil line in/out from the engine) is to get hoses made and buy an after market oil cooler. they are easy to source and lines are easy to get made up. hope that helps

try here for OEM http://www.motogrid.com/pages/parts/viewby...d/2/yamaha.aspx $225 dollars though

Hi Mark, I suggest you first get a Haynes manual and read it. Then post any specific problems you encounter along the way and we'll be pleased to help you. best post in the "workshop" or "classic" part of the forum tho' for quicker replies

schweet, what tank are you using?

Hope you all have a great Christmas and an XSive new year

yep sounds like pet cock gone, which will flood the carbs. Always use an inline filter.

Poss fuel starvation, check the pet cap has air vent unblocked and tap has no crud in it which would then point to crud in the carbs blocking main jet. you don't say which cyls go off, or is it random?

check your petcock is not leaking through the pipe. can you pull off the pipe from the carb and only a small amount of fuel runs out? next is your float height and float needle, you can get keyster kits from sirrius online and you can just replace the float needle ( as they wear and flood the carb) or if feeling adventurous, replace all the jets supplied.

lets us know how how you get on?

just buy a new one and have done, its not having it!, so bite the bullet. if you were in the uk i would have looked at it for you.

maybe ask these guys http://www.yamaha-xt500.co.uk/portal.php there may be a particular fault to this particullar model. Its frustrating for us ,as its hard to diagnose from a distance. I would get my multimeter out and check all parameters of the electrical system.

www.cmsnl.com (dutch, but they tend to have everything) www.motoward.co.uk www.bikebandit.com (USA) www.motogrid.com (USA) www.pgm1.freeserve.co.uk (rd but i buy for my XS here) www.yambits.co.uk don't use a 12v battery on a 6v bike, 6v batteries are so cheap its not worth it. Get Father Christmas to send you an Optimate for Crimbo (one that will do 6v as well as 12v) keep this on your bike in storage. I have one on mine as I write BTW the RS is an RD without an extra carb and no reed valve. Classic Mechanics has a feature in this month on your very bike!!

jim patch - phone only motoward guvenors bridge get a parts book so its easier to identify the parts you are after and not get an earlier model part which is different. (its happened to me and they also get superceded)

on mine its a 2 stage affair with a ball/sping combination in the cartbs acting on indents on the choke rod. I usually start it on full, take it right down to 1/2 way, and fully in after a minute. My bike will "drop off" the revs if left for a min or so at the lights, its down to modern fuels and old design. just blip the throttle when the engine starts shunting. you could also have a blocked pilot screw which will affect the tick over (yours might be sealed, its on top/in front of the main carb body) got an xs400d circuit diagram, which should share the colours of yours

I'm assuming that you mean it has free fuel flow rather than an external leak? is the lever hard to turn?, it should do as i have rebuilt mine and it is stiff, you need to make sure everything is in the right order off a parts or workshop manual (you can see an online version at motogrid) ensuring the rubber is the right way round and covering the right holes etc.

can you keep the bike going with revs when warmed up?

too big, i have 90/90 front and 110/90 rear on BT45 Battlax. I got an old xs250 with a 120 on and it fouled the swing arm
