^^Correct
The washer has to go between the spring and the o-ring
(to protect the o-ring from being chewed up by the spring end when adjustments are made)

Spring, washer, O ring

I'm also guessing you were over fueling with the 135 jets even with the free flowing K&N pods.

No I don't think so, if that was the case it would be fowling up all of the other 3 plugs as well...no K&N's now they are crap even though they were the correct ones for this bike, the polished velocity stacks on are spot one & work very well...ive just got to get this carb 4 sorted
