Please send your fork tubes & top nuts with "O" rings to us, for matching up ( to ensure a snug thread fit ) without sliders / boots ...degreased, so as not to destroy the packaging in transit, via a tracked and signed for delivery service ideally ... so hopefully no parts go missing. Plus a cartridge type damper rod lock nut if fitted ( send just the one lock nut ) to... 104 Walcott road, Billinghay, Lincoln LN4 4EN

Check you have adequate ride height, with the fork compression of a complete bike weight with rider & passenger... along with any extra load like camping gear etc.

 Use your top yoke as a devise to clamp & turn / tighten or remove.

2" Yamaha XS650 example below

Could work with just your original top nut supplied ( by machining a go & not go gauge around it ) instead of supplying the fork tubes. But.... but it would not be a guaranteed matched fit.
