I had the same difficulty, not having open enders in those sizes and finding the shifters that would fit too big to manouvre easily.
That's why I used the preload adjustment method initially.
Dropping the Ohlins out the bottom makes it all very easy.
Just as a rough guide I used a small tape measure to check how much clearance there was between the top of the rear tyre and the inner guard, with the bike on the sidestand, before moving anything.
The reading was 222 mm visible, so with the length of the small tape being about 50 mm that makes the clearance 272 mm.
Of course, increasing the preload won't increase this reading if the shock is already fully extended, whereas reducing preload will drop this clearance.
Thanks for the advice!
