Thruxton 2015 Thruxton 900 Efi

hi all,i cleaned & re-lubricated the chain yesterday,i have arrow 2 into 2 fitted so i have NO option of fitting a main stand,i purchased a BIKE-TEK wheel spinner it is useable but as the bike is leaning a lot to the left, the rear wheels tend's to roll off the rollers.if there a specific paddock stand available, to enable me to clean & re-lube the chain, the other query i have,i'm on the look-out for a pair of small round bar-end mirror's that will fit the OEM handlebar's.i've noticed inside the bar-end's there's a nut welded on the inside, will this be a problem fitting after-market mirror's.thank's in advance.
