I'm going to fit the airbox and carbs to the K6 project I'm building (having welded the airbox frame brackets back on that the previous owner ground off!). I remember having trouble juggling them onto my standard K2 but as it was back in 2014 ish, can't remember what was the best method and thought I would ask the experts to avoid mucho causing and swearing in this scorchio weather (sorry, went all Spanish there - must be the weather!)
