750K1 arm in an 1100K

[Toddy64]

Things have moved on a little since my last post when I reported the back end to be way too firm. 
I managed a short ride out and as expected it was a nightmare☠️

Having followed a lot of other info on this subject, I decided to contact DanM54 and get one of his adaptor plates ordered along with a K1 knuckle

Once arrived and bolted up the rear shock actually moves and with a little fine tuning I’m confident it will be fine, the dogbones even look nearer to the perpendicular too, (I think a longer shock would help further with this) the ones I’m using in the pics are 125mm and increase the ride height about 25mm, so I’m probably going for either an adjustable set or 130-135mm should put the height back to standard

The only remaining headache is the chain rubs against the edge of the vertical centre brace of the swingarm!! Now as I’m running the standard 1100k rear wheel, I took a lot of time spacing it correctly for wheel and sprocket alignment, and I’m aware the 750k1 sprocket is a further 10mm from wheel centre

So I was wondering if any of you can advise me as to the best way around the chain clearance issue, 520 chain and sprockets? space both sprockets out a few mm? grind the weld off the swingarm? (ideally I wish to keep the slingshot wheels) or fit a K1 wheel, I’m told you need to machine 5mm off the rear carrier and offset the front sprocket by 5mm to maintain alignment
