Hi all ive just bought a Honda XR400 believe to be a 1997 i have the frame and engine numbers but how do i get the reg number and V5? Help please?

Being a vertically challenged 5’7 90kg with 30” inside leg I might need to lower my (new to me)Xr400r a tad! ive bought a second hand seat and will be sending it off to get the foam shaved down a bit and a new seat cover but think it might not be enough! Was considering a lowering link but it...

hi i have an XR400 standard bike, i live in portugal and parts are hard to get, i am looking for piston ring set and top half gasket set with valve seals any idea where to get them in uk thanks kevin.:cool:

I'm trying to return my XR400 to standard specs. As it seems that many XR owners remove these items, I'm hoping that someone has a diffuser and snorkel for sale! If you do, please send me a message. Thanks.

To improve starting, I'd like to take the carb back to the original (UK) settings. I have a manual showing Main Jet 142 and Slow Jet 52. However, the manual appears to be for USA models. Would UK models have been fitted with the same jets?

Hi guys, a quick one. I've been trying to resolve my XRs fueling problem for a while now. It's main issue is that it conks out. If I rev it and let the throttle snap back, it tends to simply die. Whereas if I gently roll off, it stays running. I'm running #168 main and #62 pilot jets, clip...

Has anyone e done this modification. I like the thought of USD forks. I know I'd need the triple clamps as well but would love to know if anyone has done this mod? Ben Sent from my SM-G930F using Tapatalk

My shiny new piston and rings have arrived but which ring goes to the top? There is no edge profile to worry about but one ring clearly has a shiny edge and the other is dull. There is no marking to indicate which is the top either. So lets have a group guess shall we?????? Many thanks. Ben...

Hi Has anyone done the 440cc conversion? If so what are the benefits and drawbacks? I am about to start an engine rebuild and wondered if it's worth doing. Thanks. Ben Sent from my SM-G930F using Tapatalk

Anyone got one lying around...?

Hi. Having had the piston disintegrate into the engine on my 2004 XR400 I am now looking at a fairly major rebuild. I am ok with that but I was wondering if all the XR400 engines are the same? It certainly would make finding all the parts easier. At this time I need a new barrel, 4 valves...
