I've been watching your videos for awhile now and I love them. Great info and entertaining on top of it.
I've always had trouble with wheelies. I have zero trouble getting them well enough to get over logs now, but I cannot seem to keep it going for any length of distance. It's not the rear brake covering I have issue with either, it's just getting to that balance point and modulating the throttle and clutch to keep it going and standing up. I get so jealous when I see people do it like it's nothing. Even on my trials bike I can't seem to get back far enough to keep the weight on the back to keep it going. Must practice more. I can barely do sit down wheelies from a dead stop because I can barely touch the ground when sitting that far back on the seat. Stand up or slowly rolling is about my only option.
