Just about winning a battle to get head bearings fitted on the 400 and am a bit baffled that it is so awkward.Went for the All Balls kit which seems to be the most common offering and I have read lots of threads about problems of reduced thread for adjuster nut so tried to proceed as carefully as possible.Spent ages again Googling on this before starting but there seems to be no definitive answer anywhere regarding the spacers etc.In the end I found that only the thin spacer on the lower bearing could be used otherwise the top thread is virtually non-existent.Even with this, it is only just enough and if the dust cover and washer are both fitted the amount of thread is very small.One thread on the US site showed flattening the raised teeth on the adjuster screw and omitting the spacer (and I think dust seal) to get a bit more thread.I'm going to play some more with this still but it just seems crazy that a common replacement part is so tricky and maybe dangerous as I guess there needs to be at least a reasonable thread for the adjuster screw to fix properly.Any thoughts?Cheers,Andy
