Hi ive bought a 97 XR400R but upon inspection its got a broken valve which in turn has damaged the head too much for repair so im looking for a head preferably with valves/cam etc im in UK? Thanks in advance.

Hello, Balam from Mexico here. I have undertaken the task of calibrating my valves. All went well with rear cylinder, but my front cylinder has a problem. Intakes valves are good. Exhaust valve is waaaaay too tight. I can get no feeler gauge in! What's going on? Is my timing chain off? Is the...

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...

Anyone know the INTERNAL diameter of an RD07A front fork? There are quite a few fork valves on evil bay for other bikes for around £60 which might fit the AT but I need to know this measurement Thanks for any help John Sent from my GT-I9505 using Tapatalk

Hi there. This is my XR400 which hopefully will take me to the Sahara later this year, but not before I check the valves and cam chain. Does anyone have the valve clearances and any special info I may need. It has the standard decompression lever. Thanks in advance Ben

bike is 1800 miles off service its going to Europe possible 2500 miles max, the question I want to ask is do the valves need doing every 8k or would it be safe to leave until after trip?

has anyone tried these? are they basically a cheaper version of ricor intimators? YSS PD FORK VALVES 31mm

Hi I am new here I have just finish a full reconstruction of my AT 750 (i will try to upload some fotos).The engine has 32.000km it's from 2000 AT mine is 1995model. I want to ask a question if someone have milled the heads and if it's enough space between the head and the cylinder to do that...

Hi, don't know if any of you guys can help me ? Looking for a good used front cylinder head complete With valves, cam etc to finish the old girl off and have her back on the road for the first time in 12 years all other work done. Happy to pay good money for the right parts. Thanks

I'm wondering how difficult it is to check the valves on a 2008 Varadero xl1000. Since it is a 90*, does it make it any easier to gain access? Any tips/tricks?

The Haynes manual 3919 says that the inlet valves are covered by a cover and the exhaust valve is covered by a cap. My bike seems to have covers for both. Is that normal, maybe an evolution towards the 700? My bike is a 2007, so the last year of the 650.

Hi all, First post, but having read a lot here I'm sure I'll get some good heads up. Last time my TA had the valves set was by a main dealer at 16000 miles. I'm reasonably sure that at least the rears were done because within a couple of hundred miles I had to get in myself and renew the o seal...

Put the valves in spec' & retested the compression, reads 120 psi, any thoughts ?

Anyone got a head to fit a dominator laying about in the back of their shed, my mates got the dreaded crack between the valves and the valve seat's fallen out :(

Hi, I'm wondering if the Intiminator will fit & work in the Vara, which has 43mm damper rod forks - that really let the bike down! Are the Intiminators adjustable at all and what oil viscosity do they run? What do you reckon, worth a punt? Where is the cheapest place to purchase them from if...

How do a Barrister from London and a lorry driver from Devon end up discussing toilet cistern filler valves on Facebook chat

Actually not much. The mechanic just called and said all valves were well within spec. :cool: Here she is yesterday overlooking Geirangerfjorden: Have a good monday guys!
