O.S. 21XZ-B V-Spec Off-Road Competition Buggy Engine [OSM12180] Sean Dickinson - Rating: Verified Owner Thursday, June 21, 2012 This is a great engine. Not the easiest to break in, but after break-in, it is easy to tune and very reliable. I use P4 plugs in Phoenix, AZ and as long as I have a smooth throttle, I easily get over 10 minutes run time in a buggy. Power is smooth and very predictable, not hard at all to control and definitely worth the less than 300 price tag. Overall pleased with my purchase. 1 of 1 customers found this review helpful.
