I decided not to change fork seals before the trip simply cos I dont have the tools and the mechanic I knew and (sort of) trusted is gone as is the Yamaha dealer in my town :/ I will take a set of seals with me though.

I want to change the oil by myself without breaking the suspension down to pieces. Simply take it off the bike, drain, flush, fill and put on again. I was wondering what is the best to clean it inside (without dismantling). I was thinking kerosene or petrol. Google says kerosene is better

Also, stock fork oil is 10w, I want to go with 15w...good idea?
