Hi , I am thinking about buying a Kazuma 150 MK2 for my 15 year old son. We only ride in the sand dunes and I am concerned after reading on this forum about the power problems, starting problems, carb manifold problems, transfer case, ect. I have experience with atv's but my son does not and I thought at first this would be a great atv to learn on at a reasonalbe cost. Now I am thinking I should only go with yamaha,honda ect. Any thoughts on this or any owners of one of these atv's that have taken out one of these atv's on sand would be great. I am not looking for an atv's to blast up the biggest dunes but it need to be reliable and able to go over small hills and go well on the beach. Thanks in advance for you reply.
