I have recently replaced the original paint and am debating whether to overhaul the original engine, or to replace the drivetrain with a modern more powerful and efficient setup. I am getting about equal parts for either remaining stock with matching numbers, or improving with modern equipment. This Brat does not get driven much anymore, but it still starts and runs reliably, and is without doubt the best snow car I have ever driven. On the down side, it is all it can do to comfortably drive 70 mph, which requires 4000 rpm of 5500 available. I would appreciate any input or opinions.
