Why Use Us Over Your Local Shop?
Old school methods of seat face cutting or grinding, and valve guide repairs will not work with these high RPM motors. Many shops and even auto machine shops try, but end up ruining the head. We fix a lot of failed attempts. It takes very precise and expensive equipment, plus new machining skills to keep these heads within specs (as close as tenths of a thousandths). Poor non-concentric machining, worn seats and valves result in very hard starting, excessive wear , broken valves, poor performance, and extremely hard to tune in. Most automotive machining centers, motorcycle dealerships and repair shops are not capable of this type if precision head work. It is the difference between working on a F1 race motor compared to a commercial automotive engine!
