Just received the frame & swinging arm back from the powercoaters, have fitted new swinging arm bearings and now chosen a ZX6R shock upgrade ( as my brother has fitted an Ohlins to his race bike it was surplus to requirements).
The ZX6R shock has a smaller diameter top & bottom bush than the ZXR400, so to address this, I drilled the lower mounting holes in the shock out from 10mm to 12mm. For the top, I just used the ZX6r mount, which fits in the ZXR400 frame beautifully, but needs about 2mm taking off in order to fit. I did this with a saw.
The shock is now in, so I'll need to check where the top reservoir sits in comparison to the battery box - I suspect I'll need to modify the battery box and lose 3-4 cm, but the NC30 battery works well in my race bike, and is about 3-4 cm smaller, so I'm confident this will be a quick fix.
