I recently built a 425 for my EX and it has a lot more power it wheelies in fourth gear easy. I was riding a third gear wheelie when I went back on the rear bar. I hit the brake once on the bar but I could not get it to come back down. I though afterwards that I could either try hitting the kill switch or start downshifting to compressions brake the front end back down. Any tricks you guys know. at high speeds that balance point is tricky. Maybe getting lift on windy days from those big fenders. thanks guys.
