this was a xc race, first off i loved how my quad performed, especially the suspensoin...thanks again rocket ron's racing, but the problems i found were the the tie rods ends froze up, because of a lack of grease, and the ball joints were the same way, so lube them up. the clutch master cylinder is leaking, the rear brakes are sticking, and my rear wheel hub nuts were loose. but nothing really all that major, but just giving you guys a heads up. but as fas as passing people, absolutely no problems what so ever. this was my first time ever riding the quad, and i moved up a class, pulled the holeshot easily, and i won my class by 9 minutes, and it felt effortless. but i am overall extremey satisfied so far.
