So today I went out to our local trails to test the climbing ablity of my 700-4. Wasn't able to before since I've always have my wife and kids with me, today was solo. It climbed great even with Maxxis Zillas on it. I live in southern indiana so there's lots of old coal mines. Lots of squaw banks(steep ups and downs) . But on the last hill which was the biggest steepest most off camber hill. I got to the top front wheel on the air and it dies....... uh oh. Then wouldn't start until leveled out more. Anyone else had that?
