yeah you're right. serves me right for trying to fill a night shift. the whole forum is pretty dead.

new motorcycle parts don't come cheap. Wemoto sell good quality kit at reasonable prices. For £22 that repair kit looks like a winner.

The shim sizes have to be calculated based on a known shim and measured clearance. You should replace the buckets and shims in the places they came from - too late now. Get a workshop manual, read up on checking valve clearances, then check them and fit the correct size shims.

The OE chain on your XJ6N will be o-ring. Yamaha tend to fit DID - make will be stamped on the link plates. Scottoiler is a great piece of kit. Fit, set, forget. Never have to clean, lube or adjust that chain again.

the mod is actually to disconnect the vacuum pipe where it connects to the airbox, not the engine breather! The vacuum operates a flap in the airbox which will be disabled when the pipe is disconnected. you've over pressurised the crankcase and it's blown out the weakest point. it's not a big job to replace the valve cover gasket but you do need to have some mechanical knowledge.

go here and ask: http://trx850.motomaniac.net/forum/index.php most likely place to get help

is it an electric pump or a vaccum pump? if it's a vacuum pump then one of the vacuum hoses from the carbs will go to the pump, usually a smaller hose connection.

Is it possibly a euro bike that's had the clocks changed? Or a converter fitted? I would expect the speedo and tripmeter units to be changed together, not indiviually, pressing whichever button it might be. Does the bike have a digital odometer?

that is, as said, an 00/01 R1. Looks bog stock to me. what do you mean by a hole in the front of it?

cobblers. complete and utter.

seems to me his original post says it all

Wurth Dry for certain.

no don't do it.
