ah, I completely forgot I had made lateral clearance on inside of swingarm last year when converting from street bike to use 17x4.5" wheel with Q3+ 150/60 tyre (free MotoAmerica Jr. Cup take-offs
). Grind enough for 5mm clearance on each side. I used 3mm clearance and spray-paint I applied has not been rubbed off after 20-days @ track. Here's old photo, i'll take close-up tomorrow
Currently using factory 14/45t 520 sprockets. Going to use 415 17-18t w/56-57-58t alloy sprockets next. Smaller chain-pitch gives finer adjustments of gear-ratios along with 1-kg weight savings off drivetrain.
