Hello,my xtx front oil seals are start leaking,so its time for replacement.Now,i want to replace original oil with Motul 20w fork oil and add 35mm long spacers.I ride most of a time with my wife and front sunspension is way too soft,rear sunspension will stay original.Now,will be 20w oil overkill and will i ruin motorbike driving with this change?
Thx
