KS KLR Rider,
There are a Total of 3 drains on the KLR air box.
One above the drive chain.
One in the Front LH corner of the 'Dirty Air' side of the box, under the filter.
And finally the 'Clean Air' drain. About an inch and a half ahead of the second dirty air drain.
The Clean Air drain is there to drain potential oil mist overflow from the crankcase and potential gasoline spillage/flooding from the carb.
Spray some carb cleaner thru the back-fire screen and prove it to yourself.
Drains #2 & 3 are both above the rear fender, aft of the shock spring.
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 84,000+ miles & counting
