Sounds like the clutch basket is worn you want to replace it really.

I would, before stripping the engine down, check the oil level. Otherwise take the engine out of the frame and strip it down.

.. Hi there, i have an XJR400 myself. You really don't need a puller to remove the clutch plates. It's recommended but you don't really need it.

To answer your question, It's not difficult to replace and the parts are costly (I ordered it in japan)..

Hope you got your answer,

The First thing you have to NOT DO, is try to start it if it has been sitting for any long duration of time, 6 months or more, second, you have to remove the gas tank, drain the contents, into a can you can see in, look for a dark brown colored corpusal, in the gas, if there is some, that is an indication, that your carbs need to come apart, unless you are a seasoned mechanic, you will have to remove the carb, take the bowl off, of course you will look for the brown couloured substance again, clean the bowl,remove the pin, holding the float in placebeing carfule to secure the needle valve in its proper place after cleaning it thouroughly, remove the jet, using a tiny bit, you reem the jet hole center, taking care not to bore it out, the you run the bit in the jet hole, cleaning any debri that may be there, use carb cleaner and keep spraying it in all in puts and out puts the carb may have, then if you put your mouth to the feul input to the carb, blow in it to be sure it is clear, if not youl have to use carb cleaner and air to clean it out, air and carb cleaner is the key to cleaning it properly, some carbs need to be taken apart and soaked in a carb cleaner, before reassembly, just keep blowing air in all the inputs and out puts, to be sure they are cleared, reassemble and GO

usually for an engine that big maybe 2 and a half turns on the pilot screw

Hi Paul: I'd be suspicious that valve/cam clearances will be questionable. As components warm up they expand, so clearances get less. This is one of the maintenance items that I personally leave to the shops with trained mechanics Here is a link that will give you a LOT of information. https://www.google.ca/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=Yamaha+XJR+400+Motorcycle+valve+clearannces Cheers.

Hi, add a new ground wire and ground it to the MOTOR very important. Just take any ground wire you have and ground it to the motor.. Once that is done check agian for spark. If still no spark. Make sure the cdi box is pluged in all the way and coil leads... There is only a few things that make it stop sparking.. Stator pick up coil ground wire cdi box then coil...
Check the leads and coils.. also cables from the coils to the ignition system..
