We were riding up to Lilloet at a relaxed pace, nothing crazy. As some of you may remember, there is a Petro Can on the left hand side near the area where the little village is. And if you have a really good memory you'll remember that there is a slight left turn immediately before the gas station. This was where I experienced the tankslapper. Not just any tankslapper. This was a SCARY SHIT 4-OSCILLATION TWIST-YOUR-FORKS kind of tankslapper. I really wouldn't be embarrassed if I shat my pants. It was especially terrifying since that particular section of the road narrows from the standard highway-width and there was a concrete barrier RIGHT THERE. I'm thinking maybe there was a bump on the road that I went over while leaned over. I dunno. I was just riding at a normal pace then bam the bike stood up and the handlebars started to turn left to right then back again at about 3/4 full lock very fast. This went on for 4 reps or so. There was nothing I could do as the movement was so strong; I just let go of the bars while exerting a bit of forward pressure on the left bar to keep it turning. I was lucky and didn't have to crash, but I was riding right on the line when I magically recovered. It went away as quick as it came.
ANYWAY, my question is... what sort of suspension setting can I adjust to minimise this sort of thing? I may be guilty of screwing up the settings as I played with them at the start of the season. I also feel mini-twitches when I ride over those reflective button things on the ground while leaned over.
