I don't think they make any bolt on kits, but I did a search and found where someone did it using XR400 parts. It looks like it would be quite a bit of work, though. Here's the link.

helmut, thanks for the link. and so yea i dont think ill be doing that your right its too much work for something like that. the original reason i wanted to do that was becasue im having starting problems. i have a new batt, solenoid, starter, my neutral safety wire broke but i also replaced it and still no start. i turn the key on, the neutral light comes on, i push the start button, solenoid clicks once, and the starter spins but nothing happens. i believe im not engaging the bendix or fly or something......any input?? thats y i was going to kick start it cuz i spend all that money replacing parts tryn to get it to start and nothing work so i said f**K it! ill kick start it, turns out that was a bad idea

The starter on the 400EX don't have a bendix. They use a one-way bearing. Your one-way bearing is bad in your starter gear. It is located in the big starter gear on the back of your flywheel. You will have to pull your flywheel and the big starter gear just pulls out of the one-way bearing. Then just unbolt the one-way bearing from the back of the flywheel and replace. There's no need to remove the starter.

Part #5, the one-way bearing, but Honda calls it a clutch on their microfiche.

thanks man, so if i replace that bearing when the stater spins it will now engage all the gears to start it up??....oh and about a month before the machine just stoped starting it would only start up 50% of the time, like sometimes it would start right up and other times it would do what its doing now and times it wouldnt start id run it down a hill to start it and after riding for a few minutes if i staled out it would start up fine after it was warmed up.....idk if that helps or if thats a completely diff problem. this is a 1999 and shes been rode HARD haha

Yeah, that's what the one-way bearing does when it goes out.

For some reason they have parts #4 and 5 labeled together in the diagram above. On the Honda utility models and also on Yamahas, when you buy part #5, part #4 comes with it as an assembly. I don't know why they are listed separate for the 400EX. If that outer ring (part #4) is worn, you might have to get it too, but I would try it with just part #5 first.

Anyway, that's definitely what your problem is. I've seen that happen a lot.

Yeah, when that bearing goes bad, it won't lock up and turn the flywheel like it's supposed to. That bearing has oblong shaped rollers that lock together when you turn it one way and then they unlock and turn free when it turns the other way. That's why they call it a one-way bearing. When the starter engages that big gear on the back of the flywheel that bearing has to lock up to turn the flywheel and when the engine starts, it out runs the speed of the starter gears, so the bearing has to turn free the other way to keep from stripping the gears. I don't know if you understand that or not, it's a little hard for me to explain, but that's how it works.

As the bearing starts to wear, sometimes it will lock up and turn the flywheel and sometimes it won't until finally it gets so bad that it won't turn it at all, like yours has done.
