Hi, I just put a trailtech endurance on my 400ex and I don't think the speed is right. I put the wheel size as 1676mm. WHen I top out my EX it only goes to around 55mph. I know this thing goes faster then this. (stock 2007 gearing). Am I using the wrong wheel size? That is the size the instructions recommended. The tires are stock. Thanks so much.
