I have to admit, didn't do this today. But one of the best things I've done so far. Early 85 k100rs (euro.) left hand dimmer / flash switch was so hard to move off low beam I thought it would break everytime I moved it, so I rarely did. Found a post on cleaning so I did , no help, then I noticed the detent holes were different sizes. evidently the low beam hole is bigger so that when you flash, and let go the switch stops on low. Solution: I took an exacto knife and on the low beam detent hole basically chipped in a VERY SMALL lead in ramp on both sides. Just enough to give the detent pin a help out of the hole. Now I use the flash mode quite often , keeping my thumb on the switch while using it always stops where it is supposed to, I suppose if you just let it fly back maybe a problem might occur. Hope this can help someone,Great site, keep it going!!!!!!!
Remember bigger is not always better, this is a VERY SMALL chip!!
